Solar panels with photovoltaic technology: A step-by-step guide

Photovoltaic solar panels are becoming more and more prevalent in our daily lives. The energy transition encourages the use of alternative energy sources that help reduce carbon emissions.

Photovoltaic solar panels also have a wide range of applications, both at home and in industry.

In this post, we’ll cover all you need to know about solar panels, with a particular emphasis on self-consumption modules.

What are solar panels and how do they work?

Solar panels may appear to be difficult to operate.

But is it really?

Solar panels are nothing more than photovoltaic cells with the sole purpose of converting solar energy into electrical energy.

The process is as follows: photovoltaic cells catch photons from the sun and convert them to electrons owing to the semiconductor material they are comprised of, silicon.

Because the current generated by the solar panels is continuous, it must be converted to alternating current using a solar inverter, as alternating current accounts for the majority of the energy utilized on a daily basis.

What are the components of a solar panel?

Solar panels are made up of the following components in addition to photovoltaic cells:

  • The electrical link that connects cells.
  • EVA – ethylene vinyl acetate – is commonly used as an encapsulant. Around the solar panels, this produces a sealing layer. It is crucial because it safeguards the photovoltaic cells.
  • The solar cells are protected by tempered glass or glass, which is used in conjunction with the encapsulant.
  • On the back of the solar panels, there is a PVC sticker.
  • Fixing hole in an aluminum frame.

A photovoltaic system includes the framework where the modules are installed, the wiring, the inverter that converts direct current into alternating power, and, if necessary, solar panel batteries. as well as energy meters

What is the process of making solar panels?

A solar panel is made through a lengthy procedure that is carried out by professionals.

First and foremost, 98 percent pure silicon must be produced from bits of quartz stones extracted from a mineral vein. This product is 98 percent pure.

The purity of silicon is critical for solar panels to work well. Chemical processes such as washing and pickling are used to purify it.

Crystal development begins once the silicon is melted. Monomolecular layers are formed around a seed of crystallization or an initial crystallite.

The crystallization seed forms into a crystalline form, a monocrystal, or a polycrystal, depending on its size.

This technique is carried out at a temperature of over 1500 °C. We will obtain an ingot shape by treating the silicon in this manner.

The electrical conductors are added when the ingot is sliced into thin sheets.

Surface imperfections and cut flaws may occur after the wafers have been cut. The next step is to ensure that these flaws are corrected.

Finally, some metal strips embedded in the surface are connected to electrical contacts, which absorb and transmit electrical energy.

Types of photovoltaic solar panels

We discussed monocrystalline and polycrystalline cells in the preceding section. These factors have an impact on the type of solar panel used.

Photovoltaic solar panels are divided into three categories:

  • Monocrystalline
  • polycrystalline
  • amorphous

Monocrystalline photovoltaic solar panels are the finest grade of the three varieties of photovoltaic solar panels. These are made up of cells that are made up of a single silicon crystal, resulting in higher efficiency.

The amorphous ones, on the other hand, are the least recommended because the technology they use is outdated and the plates’ performance is poor.

We’ll go through the features of the two most common technologies, monocrystalline and polycrystalline.

Solar panels with monocrystalline crystals

Monocrystalline solar panels are ones in which the cells are made up of a single high-purity silicon crystal and solidified at a uniform temperature, allowing electrons to travel more quickly, resulting in higher efficiency and performance. Liberty.

Solar panels with polycrystalline crystals

Polycrystalline solar panels, on the other hand, are identified by their bluish tone and are made up of variously aligned crystals. Although its manufacturing process is less expensive, the composition of the product has a detrimental impact on its efficiency and performance.

What is the distinction between monocrystalline and polycrystalline materials?

Monocrystalline modules offer a higher efficiency (about 10% higher) and perform better with both direct and diffuse irradiation, giving them a distinct advantage on overcast days.

Although there is a noticeable difference at low temperatures, where monocrystalline panels perform far better than polycrystalline panels, their behavior at high temperatures is relatively similar.

Monocrystalline technology should always be chosen at the residential level because space is restricted and we can install more power with the same number of panels, and because monocrystalline cells are completely black and blend in better with the roofs. . Some well-known solar panel manufacturers

Solar panel producers may be found all around the world. Here are a few examples:

SunPower

SunPower modules are known for their dependability and longevity.

The manufacturer offers two product lines:

  • Maxeon
  • Performance

The Maxeon 3 – 400.

These modules have the following characteristics:

  • Minimum guaranteed power of 98.0 percent in the first year
  • 0.25 percent maximum annual deterioration
  • Minimum guaranteed power of 92.0 percent in the 25th year.

The P3-380-BLK model, on the other hand, is “all black,” that is, it has a black background and a black frame, and it can be more attractive.

These solar panels have the following characteristics:

  •  In the first year, a minimum of 98 percent power is assured.
  • The maximum yearly deterioration is 0.45%.
  •  In the year, the minimum assured electricity was 87.2 percent.

SunPower also offers one of the most comprehensive solar panel warranties available, covering all of its modules:

  • The product comes with a 25-year warranty.
  • Power is covered by a 25-year warranty.

J.A. Solar

The Chinese company JA Solar is another maker of solar panels.

It has grown at a breakneck pace, with its PERC technology patent standing out. This entails putting a coating on the bottom of the solar cells that reflects light. The photons that pass through the panel can be utilized in this fashion, resulting in increased efficiency.

JA Solar has a large selection of photovoltaic modules.

The JAM60S20 model, a monocrystalline module with 60 cells (120, including the fact that they are divided into two halves – Half-Cell technology) with a 380W output, is our recommendation. It includes PERC and Half-Cell technologies, allowing for better solar production optimization.

A 12-year product guarantee and a 25-year production warranty are provided by JA Solar.

FuturaSun

FuturaSun is another well-known brand that we like to suggest.

Solar panels, both monocrystalline and polycrystalline, of various powers, are available from the company.

We can use the following models in our residential solar installations:

  • SILK PRO-FU 380M
  • SILK PRO-FU 375M
  • SILK PRO-FU 370M

The product is covered by a 15-year warranty, and the performance of the photovoltaic modules is covered by a 25-year warranty.

The installation of the modules

Now that you know what solar panels are and how they work, what they’re made of and how they’re made, the different sorts, and the most well-known brands around the world, it’s time to talk about solar panel installation.

The first and most significant point to make is that solar panel installation should only be done by certified installers.

Clover Energy has a large network of installers all throughout the United States. We are able to provide a quick, high-quality, and close-by service in this manner.

Straight to the point!

The following are the steps for installing photovoltaic panels:

  • Assemble the support framework for the installation.
  • The framework and panels are being fixed.
  • Connect the power inverter to the outlet.

However, mounting the modules is only a minor part of the whole procedure of installing a self-consumption system in a home.

The following steps must be followed in order to have a working and legal solar installation:

  • The certified installer should provide you with a technical report.
  • Obtain all essential permissions, which we will go over later.
  • Installation of the system.
  • The same should be legalized.

Requirements that must be met by the cover

However, in order to install the modules, a number of prerequisites must be completed.

We’re mostly discussing two types of requirements for photovoltaic panel installation:

  • They have something to do with the roof on which they will be installed.
  • Requirements pertaining to the legal aspects of the installation procedure.

The cover that will be used to install the modules must be in good working order. If there is any damage, it is advised that it be repaired before the installation.

Deterioration of the cover during installation is possible if it is in bad condition. Furthermore, repairing it after installation would necessitate disassembling and reassembling the system, raising the expense of repeated repairs.

The slope and orientation of the roof are very important, as we will see because they impact the performance and profitability of the photovoltaic system. For the same reason, it’s crucial to keep any shadows on the modules to a minimum.

Legalization and permits

These aren’t the sole prerequisites for installing solar panels.

For the installation of solar panels, you’ll also need to get a number of licenses. We’re talking about permits both before and after the work to legalize it: design of the installation, access and connection permits, building license and taxes, prior administrative and construction authorization, environmental and utility authorization, and prior administrative and construction authorization. certificate of completion of work for the general public

Following completion of the work, the following procedures must be followed: initial and periodic inspections, registration of the self-consumption installation with Industry, access contract for the self-consumption installation, energy supply contract for auxiliary services, surplus compensation contract, and representation contract.

Procedures such as the surplus compensation contract are not required if the installation is isolated.

In addition, to be able to authorize the installation, you must have certified installers.

Clover Energy manages the necessary permissions and collaborates with a large network of approved installers to provide complete solar installations to our clients.

A photovoltaic system is made up of several components

When we talk about installing a solar panel system, we’re not only talking about the modules themselves; we’re also talking about other factors.

A solar panel system consists of the following components:

  • Photovoltaic modules are solar panels that convert sunlight into electricity.
  • The photovoltaic module structure.
  • The investor.
  • The wiring.
  • Lithium-ion batteries (optional if you decide to disconnect from the power grid).

Prices

Let’s talk about the costs…

When it comes to making the decision to go self-sufficient, one factor that cannot be overlooked is the cost.

A monocrystalline solar module based on PERC technology, such as the ones we use, can cost up to 200 euros. It also varies according to the manufacturer.

However, when it comes to photovoltaic installations, our costs cover all essential components and labor.

The cost of our solar installations is determined by the province in which they are installed.

Why?

We are able to do this because we have a large network of installers who specialize in cost models.

Furthermore, our installer comparison system distributes projects to the best installer in the area, resulting in nationwide competitive pricing due to work efficiency. In no way does this jeopardize the quality of the installation; on the contrary, it enhances it.

Solar panels for self-consumption vary in price based on the quantity of modules required and the Constructions, Installations, and Works Tax, which is typically around 2-3 percent of the installation’s value.

We’ll take Dublin as an example because we have very competitive pricing models there.

The following are some examples of solar panel installation prices:

DimensionPrice€/Wp
5 modules€3,4001.89
10 modules€4,9001.34
15 modules€6,4001.08

The integration of batteries is not included in this pricing. These raise the system’s final cost, but they also increase the amount of self-consumed energy, resulting in larger electricity bill savings.

Maintenance

Solar panels have the advantage of requiring little upkeep.

And what exactly does that imply?

Maintenance of solar panels entails:

  • The modules are being cleaned.
  • Defective parts are replaced.

Cleaning the plates is simple and does not necessitate the use of specialized equipment. It is more important than everything else to keep the cells’ surfaces clean so that they can absorb the maximum amount of solar light. Cleaning with the hose is typically sufficient.

If the dirt will not come off with mere water, you can use a mild scourer that will not scratch the plates’ surface.

If damaged parts are still covered by the manufacturer’s warranty, they will be replaced free of charge.

Guarantees and insurance

Aside from maintenance, insurance is another option to safeguard a solar panel system.

When it comes to solar panel insurance, it’s crucial to understand that the situation differs depending on whether we’re talking about self-consumption or businesses that specialize in photovoltaic energy generation.

Dedicated insurance can help energy businesses protect their systems. Theft and pillage are frequently covered, as are fires, explosions, and lightning, as well as damage to facilities and electrical appliances, as well as loss of profits, and mechanical breakdown.

In the case of self-consumption systems, house insurance is required to cover the plates.

However, you should check with your insurance company to see if the system is classified as a container or content.

If it’s classified as a container, all you have to do now is tell the firm that it’s been installed. When it comes to content, on the other hand, insurance for the home’s contents is required.

Module makers, on the other hand, provide warranties on damaged modules.

The guarantees provided by the manufacturers are listed below:

  • JA Solar provides product guarantees of 12 years and performance warranties of 25 years.
  • SunPower offers a 25-year warranty on both its products and their performance.
  • FuturaSun provides a 15-year product warranty and a 25-year performance warranty.
  • LONGiSolar, like JA Solar, provides a 12-year product warranty and a 25-year performance warranty.
  • Trina offers 12- and 25-year guarantees, just like LONGiSolar and JA Solar.

This means that if the modules or their performance fails before these requirements are satisfied, the manufacturer’s technical service is obligated to correct the problem.

Tilt and orientation

As previously indicated, the direction and inclination of the solar panels are also crucial considerations. The photovoltaic production will be harmed if the orientation and inclination are not correct.

The south is the best position because it provides more hours of direct sunshine every day. Because they can’t be orientated to the south, they can be evaluated for a west or east orientation, adjusting the inclination.

Orienting the solar panels towards the north is not suggested under any circumstances since the amount of sun that strikes the surface of the modules will be reduced.

It is dependent on the region of the country in terms of its predisposition. If we take the average, we can say that Ireland has a 45º inclination. However, inclinations of 55º can be found in the north of the country, while 35º can be found in the south.

Because the sun’s rays fall perpendicularly on the planet, the closer the installation is to the equator, the fewer degrees of tilt will be required.

How to calculate the size of a solar panel installation

The correct dimensioning of a system, as well as its orientation and inclination, have a significant impact on its profitability.

We’ll go over how to size a solar panel system, but first, we’ll go over how big photovoltaic modules are.

The modules’ dimensions

The number of cells that make up a solar panel determines the size of the panel. In this regard, 60 cells, arranged in six rows of ten cells, are the most popular in residential use. The size of these solar panels is 164cm x 99cm.

However, larger variants are available, like the 455W Trina modules, which measure 2.12m × 1m and include 72 cells.

Those for industrial usage, on the other hand, have 72 photovoltaic cells and measure 2 meters by 1 meter.

How do you figure out how many solar panels you’ll need?

To figure out how many solar panels you’ll need, multiply your home’s electricity consumption by the solar panels’ power output.

If we run the calculation for a monthly bill of €100 and solar panels with a high output capacity, we get the following results:

One module can generate up to 500 watts. An average of 5,000W is generated by a monthly billing of around €100. As a result, if your monthly bill is roughly €100, the best size of your installation is most likely 10 photovoltaic modules.

This is still a very speculative guess. It is vital to examine your bill and size according to your real consumption for a good installation. If the installation becomes isolated, more plates will be required to create more energy, which will be stored in the solar batteries to provide a continuous supply.

Is it necessary to install more plates than are required?

The fundamental concept is to save using a photovoltaic self-consumption system, regardless of whether you are connected to the network or not. In the case of isolated installations, the solar panels must produce the same amount of electricity as the house consumes.

However, we must keep in mind that in a typical single-family home, energy usage is low for much of the day and that the solar panels will be producing energy that will be stored in the batteries at all times, even when the house is vacant.

If, on the other hand, the installation is connected to the network, it will not be compensated if the amount of excess energy produced exceeds the amount of network energy consumed in price, resulting in a loss of production that is injected into the electricity company’s grid without any compensation.

Because the initial cost was higher and the excess is less remunerated than self-consumption, amortizing the investment will take longer if the photovoltaic system is enormous and not all of the energy fed into the network is reimbursed.

Performance and power

Power and performance are two other essential factors that distinguish one solar module from another. The following factors influence the power and performance of photovoltaic solar panels:

  • The cells’ kind.
  • The total number of cells in the module.
  • Solar radiation and the climate in the area where the system is installed are two factors to consider.

Although all of these factors influence the performance of a solar panel, photovoltaic cells are the most important in terms of electrical power.

Between 0.5 and 0.6 volts can be generated by a photovoltaic cell. To calculate the panel’s power, simply multiply the number of cells by the power of each one.

If each cell produces 0.6 volts on average, a 60-cell solar panel will produce 36 volts of electricity.

How to choose the right solar panels for your home

When choosing solar panels for your home, there are several factors to consider, not the least of which is their size.

We discuss the following topics:

  • The type of solar panels and the quality of those panels
  • The house’s total energy consumption
  • The dimensions of the modules

Monocrystalline solar panels, as previously said, provide the best performance. These plates are recommended to ensure the highest generation of electrical energy and, as a result, a faster return on investment.

When it comes to size, solar panels with 60 cells are recommended for single-family home installations.

Finally, you must know the amount of food consumed in order to determine the number of plates required. As we’ve seen, a module can provide up to 500 watts. Depending on the amount of usage, one or more modules will be required.

The savings and the profitability generated

The price of the system, the amount of aid that may be acquired, and the amount of energy produced all influence the profitability of solar panels. The potential for electricity generation in a country like Ireland, which has between 1100 and 1600 hours of sunshine per year, is enormous.

In addition, the central government and several municipal governments around the territory are supporting photovoltaic self-consumption by providing financial assistance in the form of personal income tax reductions.

Even without these benefits, solar panels are profitable due to the fact that the energy is self-consumed. Companies or households that choose self-consumption may get a 50 percent reduction in their electricity price.

Self-consumption of energy during the day provides savings.

Compensation can also be earned for surpluses discharged into the network, although as previously said, this is not a company, but rather a tool to help amortize the investment.

In a nutshell, the annual profitability of a self-consumption system ranges from 10% to 15%.

The uses of Solar panels and applications

There are numerous benefits to installing solar panels on a home.

Modules are a highly adaptable energy source. Solar panels can be used for a variety of purposes, ranging from home lighting to public transportation.

Solar panels are primarily used for the following purposes:

  • Appliances for the home
  • Heating
  • Water that is extremely hot
  • Air-conditioning
  • Aquatic center
  • thermostats
  • Luminescence (public or private)
  • Caravans or electric automobiles
  • Planes
  • Boats
  • Irrigation
  • Devices for recharging mobile phones or other related devices
  • Textile manufacturing
  • elevators

The advantages of photovoltaic solar panels

Whether we’re talking about solar farms, industrial panels used in huge buildings, warehouses, factories, or solar self-consumption, the benefits of solar panels are numerous.

One of the most significant advantages of all methods of solar power generation is that they contribute to environmental protection. Solar panels generate energy that is completely clean. Climate change, today’s turning points, and the ecological transition that the times demand and governments want to encourage, all welcome this sort of energy to take a greater role in the energy mix.

Furthermore, it must be remembered that solar energy is a renewable resource, as the sun will never run out, at least not in the next million years.

Furthermore, we must not overlook the cost savings that these technologies provide. Solar panels will ensure a low electricity cost, taking into account the present energy market and its volatility.

Solar panels are an entire universe in and of themselves. They are a terrific alternative to old energy consumption because of all the applications they can be put to and all the benefits they can provide on a personal and global level.

Furthermore, they are getting more profitable by the day, as technological advancements boost their power-producing capability and the government encourages a shift to clean and renewable energy. Each of us is the catalyst for change.

Batteries for solar panels a cost-effective way to reduce your utility bill

Solar batteries, while not required, are an important part of any photovoltaic system. Because they store the energy produced by solar panels, these reduce electricity expenses. Instead of being fed into the electrical network, the energy can be self-consumed, resulting in lower network energy use.

Are batteries the answer to getting off the grid and becoming self-sufficient in terms of energy?

No!

And we’ll explain why that is, as well as what the best solutions are for incorporating a battery into a self-consumption system.

What are solar batteries or accumulators, and how do they work?

These solar batteries are an important component of a self-consumption system that allows solar energy to be consumed after it has been generated.

They are, like any other energy accumulator, devices that store the solar energy generated by a photovoltaic system.

These batteries are charged during solar production hours and store that energy for use when the sun is not shining or when it is more convenient to consume one’s own energy rather than relying on the electrical grid. The solar inverter, the brain of the installation, or a charge regulator connects the photovoltaic modules to the batteries for solar panels. We’ll go into the interoperability of these two devices later.

Types of solar batteries

Depending on the technology utilized by battery makers for solar panels, there are different types of solar accumulators.

 

Because not all solar installations require the same type of energy accumulator, it is helpful to understand all of the distinctions in order to make the best battery option.

The batteries are classified into the following categories based on the technology used to make them:

Open Lead Acid Batteries: Open lead-acid batteries are a low-tech alternative. The battery has a lifespan of 300 charge cycles, which implies it will last less than a year if charged and discharged once a day. They are designed for low-power use, such as motorhomes, and can be discharged up to 60%, whereas batteries made with more modern technologies may be discharged completely. Maintenance is required for these batteries.

AGM batteries: like open acid batteries have a short life cycle of 500 charge and discharge cycles, which is higher than the previous ones. They’re also utilized for caravans, and they may discharge up to 60% of their load. They have the advantage of not requiring maintenance over open acid ones.

Gel batteries: on the other hand, can be utilized in homes if they have a very low power consumption. With 1,200 cycles of use, these have a longer functional life. They also download up to 60% of the time.

Stationary solar batteries: Stationary solar batteries have superior technology and can handle up to 3,000 charge and discharge cycles. You can also download up to 80% of the content. These are beneficial for huge residences or homes that are not connected to the electrical grid.

lithium batteries: Finally, lithium batteries, which are highly popular, provide up to 6,000 charge and discharge cycles, which is nearly 100 percent. They’re made for households that have a lot of energy consumption or are secluded from the rest of the world. Another benefit is their lighter weight.

How do you go about selecting the best solar batteries for your home?

The size of the photovoltaic installation and the energy usage of the home influence the battery selection for a self-consumption solar panel system.

Assume we have a home with a yearly energy demand of 6000 kWh and a solar panel installation of 10 380W panels.

It is recommended that a battery with a capacity of 5 kW be installed (5 kWh of energy). A battery with 10 kW of power (10 kWh of energy) is recommended for a 14 380W panel installation.

In order to charge batteries and self-consumption at the same time, it is usual practice to oversize the system in terms of battery charging power.

When it comes to pricing, certain batteries are more expensive than others. A battery with a capacity of 5 kW costs roughly €3,000, while the greatest power can cost up to €5,000. As a general guideline, we seek a battery that allows us to store as much energy as we will require till the next day. This does not indicate that we will always have energy in the battery, but it does assist in balancing investment and profitability when determining the capacity of a photovoltaic system.

The benefits of solar batteries and the money saved

Because batteries raise the cost of a solar system, its profitability is lower than in systems without them.

A system with integrated batteries, on the other hand, can save you money on your electricity bill. For individuals trying to save the most money on their electricity bill, the battery is the ideal solution.

If we consider an average system with less than 4 kWp installed and a 5 kWh battery, we can self-consume up to 85% of the energy produced, resulting in less energy being discharged into the electricity grid.

Because the kWh acquired from the electrical grid is far more expensive than the kWh sold, which is roughly €0.06, this can reduce the electricity bill by up to 80%.

Furthermore, the battery is especially beneficial between 7:00 p.m. and 10:00 p.m. in the context of electricity tariffs with three-time slots.

Photovoltaic production is minimal between these hours, especially during the winter months when it gets dark early. Due to poor sun irradiation, it is low even in the summer months.

Furthermore, between 6:00 p.m. and 10:00 p.m., the price of kWh skyrockets, making rush hour the most expensive time of the day. Using the battery during these hours will save you more money than if you use it at night.

What does it mean to be disconnected from the network?

Installations with batteries that are still connected to the energy grid are among our examples.

Why? They bring the largest profit margins.

Many people link battery to use with energy independence; nevertheless, the investment required to achieve it would be significantly larger than in the case of connected installations.

Furthermore, there is always the possibility of running out of power. If it rains for days on end, photovoltaic production is reduced, resulting in a significantly faster discharge of the batteries. That is why, even with batteries, we do not recommend unplugging from the electrical grid. It could be the simplest way to transport yourself back to the Middle Ages.

But, how much is an installation with solar batteries that can be removed from the grid going to cost?

Consider the size of an installation that might function for two days of constant rain.

This will require 30 380W solar modules with a total installed power of 11.4 kWh and a 20 kWh battery.

The estimated cost of an installation of these sizes is €28,000, with the battery accounting for €15,000 of that.

This is a subjective situation; this may be a client who is dimensioned to work without the system producing electricity for two days during a rainstorm. However, it does not ensure self-sufficiency.

To withstand a week of rain, a system would need batteries with a total capacity of 140 kWh and enough modules to charge it in one day. It will be determined by the intended use, electrical requirements, and the amount of expenditure that may be assumed, among other factors.

A generator is another option to ensure supplies in the event of a power outage. These machines, however, run on gasoline, and their use is harmful to the environment.

As a result, we do not advise disconnecting from the network.

Disconnecting has only one benefit: it can save you money if you have a power outage. Despite the presence of batteries, the electrical supply to associated installations will be switched off for safety reasons.

A backup system is one way to ensure that a power outage does not harm your home.

What exactly is this? It entails installing a new circuit separate from the electrical network that is activated to feed the home in the case of a power outage.

It’s possible that the entire house will need to be rewired.

The supply is not interrupted in the event of isolated installations.

Manufacturers of well-known solar batteries

Compatibility with inverters is an important consideration when buying a battery. That is why we chose to work with a variety of brands in order to have batteries that are compatible with all of the inverter models we use in our facilities.

In order to incorporate batteries into a photovoltaic system, hybrid inverters are required. The battery models from these manufacturers are listed below, along with their capacities and inverter compatibilities.

Below we present the battery models of these manufacturers, the powers of each one, and the compatibilities with the inverters:

Even though it is not a hybrid, the SMA Sunny Boy Storage is not an inverter, but rather a device that allows the SMA Sunny Boy inverter to be connected to a solar storage tank.

The return on investment for a solar panel and battery combination

We ran a simulation to assess how long it would take to recoup the cost of a solar panel system with batteries. In this instance, it is assumed that the residence is still connected to the network, despite the presence of batteries.

We took into account the following factors when calculating how long it takes to amortize:

  • The 3.4 kWp installation with a 5 kWh battery is estimated to cost €7,925.
  • The home’s annual consumption is 5,975 kWh.
  • €0.19 per kWh is the average price.
  • A 2% rate of inflation.

Although the house can save all of the energy expenditures each year, this profitability comes with a higher risk than keeping connected to the network; if the house goes without electricity for several days, the house will be without power.

This is an exorbitant danger for most households, thus even with batteries, every home on the network should remain linked.

How to get from self-consumption to self-consumption with integrated batteries:

  • You can pay cash for your system.
  • Financing can be obtained by applying for a loan from your bank.
  • You can pay a monthly charge to rent your solar panel installation.

Final thoughts on solar batteries

There are benefits and drawbacks to using batteries with solar panels. The biggest benefit is that you are no longer connected to the electricity grid. Many residences aspire to be self-sufficient in terms of energy, and others are located in remote places where connecting to the network can be difficult. However, in the nineteenth century, this represents a significant risk if days pass without the sun, leaving the house without light.

A system with batteries, on the other hand, is more expensive than one without, and it must be remembered that solar modules have a longer usable life than batteries. In addition, some of them require upkeep.

How Are Solar Panels Made

Do you have any idea how a solar panel is constructed? Solar panels, as is well known, are one of the possibilities for reducing energy use. The gadget that uses the energy of the sun to generate heat or electricity. There are two sorts of panels to choose from. The first are sun collectors, which generate hot water. These are typically designed for home usage and operate on solar thermal energy.

The photovoltaic panels are another option. Those that produce electricity from solar radiation that strikes the panel’s photovoltaic cells. So, how do you go about making a solar panel? We’ll go through this in more detail later.

What type of material is used to manufacture solar panels?

material is used to manufacture solar panels

Silicon is the most common and widely used material in the production of solar panels. Cutting crystalline silicon into small discs is a step in the manufacturing process for solar panels. A thin layer of glass is another component that is used and placed in solar panels. This serves as a safeguard for the silicon panels.

A substrate is attached to the solar panels after the bond between the glass and the silicon panels has been completed. This is accomplished by using a thermally conductive cement, which prevents the panels from overheating.

Solar panels are also made up of two intercalated materials known as semiconductors. Materials are composed of millions of atoms, each of which generates a negative and positive charge. Silicon, as previously stated, is the material used to create these positively and negatively charged stimuli.

This is available in three different configurations: monocrystalline, polycrystalline, and amorphous silicon. The monocrystalline silicon base is the most efficient of the three options. It is, however, the most costly option.

Types of solar panels:

  • Solar panels with monocrystalline cells: Ideal for cramped quarters. Having higher efficiency under normal conditions.Monocrystalline cell solar panels
  • Solar panels with polycrystalline cells: In high temperatures, these panels are more advantageous because they produce more energy.Polycrystalline cell solar panel
  • Panels made of thin plate: Due to the scarcity of silicon, methods of lowering materials and production costs began to emerge. Making panels out of thin copper, indium, and selenium plates. A thin layer of cadmium and tellurium is also present. Large solar parks can now be built thanks to advanced technological processes and these materials.Thin plate solar panels
  • Panels made of flexible cells: These less rigid cells make it possible to incorporate solar energy into other items such as clothing, backpacks, and umbrellas, among others. This allows portable electronics to be charged while out walking, for example.Flexible cell panels
  • Panels that are transparent: These are made of thin semitransparent layers that allow them to be included without detracting from the aesthetics of the structures. Getting rid of tinted windows. It is important to note that solar panels are not only used to generate electricity in these cases. However, it is also used to cool buildings.Transparent panels

These are some of the different types of solar panels available today. Which ones are produced in greater or lesser quantities depends on the country. Depending on the budget and materials available.

Duration of solar panels:

Although solar panels are an excellent way to reduce our electricity bill. They are also a significant investment, so it is critical to understand whether the energy transition will provide a good return on investment. The majority of people always have two questions.

How long do solar panels last? Solar panels have a lifespan of more than 25 years. Solar panels, however, will always be exposed to the elements, whether they are installed on the roof of a house, business, or other structure. The sun’s rays, wind, and climatic changes are gradually deteriorating the panel.

It is important to note, however, that its efficiency typically decreases by 10% at the end of such a long period of time. They continue to work, however. Solar panels can even be expected to last for 40 or 50 years.

Once the solar panels are in place! How frequently do they need to be maintained? Maintenance is not required unless there is a problem. Any change in the electrical system to which the panel is connected causes this.

Cleaning is only required when dirt or garbage accumulates. Which will be determined by the location and location of the panels. And, if there are trees near the solar installation, the branches that can block the sunlight must be removed.

Solar panels have a number of advantages that make them one of the most solid energy-future alternatives. As a result, its use is becoming increasingly popular around the world.

How Do Solar Panels Work At Night

According to new research from scientists at the University of California, solar panels will be able to generate electricity 24 hours a day, even at night.

Solar panels are one of the most common methods of generating renewable energy from solar energy. To date, their only issue is that they are unable to generate electricity at night.

There is an old joke about three scientists discussing their respective countries’ space projects to travel to space. To avoid exposing myself, I won’t say where each one comes from. The first two are about traveling to planets in our solar system, each one further away. The third, on the other hand, is unchecked and ensures that his country will travel to the sun. Incredulous, the two scientists question him on how he intends to travel to the sun, a ball of incandescent fire. The scientist responds, “Of course, they’ll travel at night.”

When it comes to obtaining electrical energy from sunlight, the main disadvantage is that there is no light at night, so the photovoltaic cells do not function for a number of hours. The same thing happens to the propellers in wind power plants when there is no wind.

But it appears that scientists have not ignored this problem and have thought long and hard about how to use solar panels even at night, an idea that may appear as absurd as the joke I told at the start but which, all things considered, would be the ideal solution for the first-order solar energy power source.

Researchers at the University of California, however, believe that it is possible to design solar panels that operate at night by capturing invisible infrared light from the Earth. These panels could generate approximately 25% of the electricity produced by a solar panel during the day.

Light and heat: Thermoradiation to The Rescue

Photovoltaic technology today is dependent on sunlight that reaches the earth during daylight hours. However, that light goes out at night, and the solar panels stop producing electricity.

What if, on the other hand, we used our planet as a heat source and the night sky as a heat sink? This is where thermoradiation comes in, a specialty that, in theory, could use the night hours to generate electrical energy from the heat generated by those same solar panels during the day.

Thus, thermoradiating photovoltaic technology could use heat instead of sunlight to generate energy both day and night. Obviously, the concept is the work of Tristan Deppe and Jeremy Munday, not mine. The second is a professor at the University of California, Davis’ Department of Electrical and Computer Engineering. Meanwhile, Munday graduate student Tristan Deppe.

According to both theories, adapted solar panels would yield roughly 50 watts per square meter at night under ideal conditions, which is about a quarter of what solar panels currently output during the day.

In January, Deppe and Munday’s proposal was published in the specialized journal ACS Photonics under the title Nighttime Photovoltaic Cells, Electrical Power Generation by Optically Coupling with Deep Space, which translates to “Night photovoltaic cells, Electrical Energy Generation by Optically Coupling with Deep Space.”

A hot object emits heat in the form of infrared light, according to its maker. Of course, because a solar cell is cooler than the sun, it absorbs the light it receives. Because space is very cold at night, a hot object oriented on the sky would radiate heat, a principle that has been used to cool buildings and things and might also be used to create electricity.

Munday is working on small scale prototypes of these novel solar cells at the moment. The goal is to increase the efficiency of these panels so that they can produce more energy in less time and with a smaller installed area. The future will reveal whether thermoradiating photovoltaics can be used and are effective in this application.

How Efficient Are Solar Panels?

How Efficient Are Solar Panels?

How Efficient Are Solar Panels?

How Efficient Are Solar Panels?

The energy transition is a global reality, and the use of solar panels for photovoltaic self-consumption or to generate electricity for grid sale, all from solar energy, will be critical in this transition.

Assume you are considering installing a photovoltaic self-consumption installation with solar panels for light to save money on your home or business. In fact, taking advantage of that space that we do not use (the roof) to generate electricity with solar energy and save on the electricity bill is one of the most significant benefits of solar energy.

However, you have realized that you do not have a lot of free space on your house’s roof, or you want to install the highest possible power to optimize the energy generation of the surface of your roof, or you simply want them to be high-quality solar panels to avoid future problems.

In those cases, you must seek out the most efficient solar panels on the market in order to make the most of the available space on your roof, house, or ship. As a result, you must always be aware of which solar panels are the most efficient.

Efficiency of Solar Panel:

You should be aware that, of all the different types of solar panels available, those with the highest efficiency and performance are those that use monocrystalline technology or are based on it.

That is, you will be able to install more power on your roof in the same amount of space as if you had used less efficient solar panels. Finally, it is necessary to determine how many Watts per square meter these solar panels have.

The more watts per square meter, the higher the efficiency.

Furthermore, it is usually fulfilled that the solar panels with the highest efficiency are also the highest quality available. At the moment, the LG Neon solar panels and the SunPower MAX3, MAX2, and P19 would be the clear winners. But we’ll find out later.

Today, it is very common, if not desirable, to find ourselves in the midst of projects, tenders, and offers. They refer to solar panels with an efficiency of 16-17 percent as high-efficiency panels, which is incorrect.

A solar panel’s efficiency of 16-17 percent is standard; this does not imply that it is neither good nor bad; it is simply standard. But it is not, without a doubt, efficient.

Solar panels with a high efficiency of 19% can be considered.

It is also true that many articles about the efficiency of solar panels can be found on the internet nowadays, but after reviewing many of them, we have to say that the majority of them are incorrect.

Some are out of date, and many others are simply false in order to gain a commercial advantage.

Because of the outdated articles, you must understand that solar cells are progressively improving their efficiency year after year, so solar panels of efficiency X will most likely improve in 1 or 2 years. As a result, the best solar panel lists should be updated at least once a year.

The fake items, on the other hand, fall off under their own weight. You’ll recognize them because they usually talk about Chinese brands, show prices, and don’t provide any documentation proving that the efficiency is real and superior to other panels. It’s pure commercial misinformation with no rigor.

Simple trick: If you want to know how to distinguish between efficient and inefficient solar panels, look at both the power and the square meters of the solar panel. Watts per panel / surface = efficiency. The greater the number, the more efficient it is.

So, in this article, we’ll show you the top ten most efficient solar panels currently available on the market.

Solar Panel Technologies and Efficiency:

As you may be aware, there are two main technologies in the photovoltaic industry: Monocrystalline and Polycrystalline. Good, however within Monocrystalline, there are a variety of technologies, some common, such as PERC panels and PERT and some unique, like as Panasonic’s HIT and SunPower’s IBC (Maxeon).

To view a REAL graph of technologies and their efficiency, we’ve included a report from EnergyTrend from 2020 that illustrates precisely that a comparison of the different types of technology and their efficiencies:

Graph with solar cell efficiencies and panel powers
Graph displaying the efficiency of solar cells and the power of solar panels based on the technology used.

To explain the comparative efficiency graph a little further:

  • Panel power is shown on the left Y axis. That is, depending on their technology, how much power each of the solar panels can produce.
  • The types of technology are depicted on the X-axis (bottom). They are P-Multi (Polycrystalline), P-Mono (Monocrystalline), and N-Mono, in that order (High purity Monocrystalline).
  • The cell efficiency in each case is shown on the Y axis on the right. Keep in mind that cell efficiency, not panel efficiency, is important (always a little less).
  • The green bars represent the standard power of that technology as well as its efficiency. For example, the standard for the P-Mono PERC (PERC Technology) is 300W with a cell (not panel) efficiency of 21.4 percent.

As you can see, the most efficient solar panels are those that incorporate HIT and IBC monocrystalline technologies, both of which use type N silicon. That is, Panasonic and SunPower are fundamentally different.

Panels that use Mono PERC technology with P-type silicon would be a step forward.

Finally, the least efficient solar panels are those that employ Multi (Polycrystalline) technology, which also employs P-type silicon.

As a subheading, mention that panels made with type N silicon are of much higher quality than the rest, because this type of silicon is the purest available in the photovoltaic industry. Type P silicon, on the other hand, is a type of silicon with some impurities, and as a result, among other factors, it never achieves the efficiencies of a type N silicon solar panel.

When it comes to panel efficiency, this is the reality of the photovoltaic industry.

The following are the 10 most efficient solar panels available on the photovoltaic market:

Once the issue of the efficiencies of each technology has been resolved, we present a list of solar panels with the highest efficiency in the current photovoltaic sector.

They are as follows:

This is an updated version for August 2021 that includes the highest efficiency solar panels available in the current photovoltaic market.

All of them are verifiable and verifiable, simply search on each manufacturer’s website for the technical sheet of each of these panels and see where they indicate the efficiency of each of these models. Then it is up to each individual to decide whether the cost of solar panels compensates for the difference in efficiency when compared to less efficient alternatives. We argue that if it compensates because the performance over the next 25 to 30 years will be higher, and then there are cases where there is limited space and it is necessary to maximize the installed power that there is no choice but to use these “super panels.”

We did not discuss bifacial solar panels in this article for one reason:

Because it is a newly implanted panel, there is no real data on how much more it produces on its back side. In fact, knowing is completely unpredictable.

The aforementioned current bifacial panels, on the other hand, have a number of issues with shadows cast on the back of the cell by panel components such as the junction box, cables, and even the panel frames, which can cause hot spots in the long run.

But first, let’s take a closer look at the market’s two efficiency leaders, the LG solar panels and the SunPower ones.

So far, the article for today, which will be updated as new features emerge.

Because no one is perfect, if you know of any other models of solar panels available in ireland that are more efficient than those shown, please contact us and we will analyze them to add them to the list.

How Many Solar Panels Do I Need?

How Many Solar Panels Do I Need

The number of solar panels required for your home will be determined by how much and how you consume. The table below shows an indicative table based on consumption level (low, medium or high).

Number of solar panels according to consumption:

Number of panelsConsumption
2 – 4Up to 2,000 kWh
5 – 72,000 – 5,000 kWh
From 7More than 5,000 kWh

How many solar panels do I need based on the cost of my invoice?

Similarly, we can estimate the number of solar panels required for our photovoltaic installation based on the cost of our monthly electricity bill. It is important to remember that the price of the bill is determined by the amount of electricity consumed, but the rate that we have contracted also has a significant impact. To give you an idea of what you’ll need, based on average spending, you’ll need:

Number of Panels

Cost of My Invoice

3 – 4Up to € 50
5 – 9Between € 50 and € 100
9-10More than € 100

A photovoltaic self-consumption installation in a single-family home, for example, will require an average of three 320W solar panels for every 2,000 kWh of annual consumption. To properly select the number of plates required in our home, we must consider the characteristics of the panel as well as the characteristics of the home.

What are the factors that influence the size of solar panels?

The characteristics of each module determine the amount of energy produced by solar panels. The following are the most important considerations:

1. Capacity

The ability of the solar panels indicates how much electricity the modules can generate from solar energy. The power produced by the plates is calculated as follows:

Theoretical power * Panel count * HSP * percent

2. Performance and quality

The quality of the solar panels used in our installation will affect not only the cost of the solar self-consumption system, but also its performance and durability, and thus the payback period. As a result, it is critical to assess the type of solar panels we will use and select a manufacturer with extensive experience and a good reputation in the photovoltaic market.

Microinverters in high-end panels enable energy production to be optimized when there are shadows.

3. Orientation and proclivity

The optimal inclination of the solar panels will differ depending on the month and province. For example, in January, the ideal angle for a self-contained facility in Córdoba is 62o, and in June, it is 4o. Changing the inclination of the solar panels every month is costly; therefore, it is best to use an optimal global inclination, which in the case of Córdoba is 34o.

On the other hand, the orientation of the solar panels is critical to optimizing the installation’s performance. To maximize electricity generation, photovoltaic modules must be well oriented to the south.

What if my installation is not oriented southward?

You should not be concerned if your photovoltaic installation deviates from the south by 30 – 40o. Solar panel systems facing southeast or southwest experience losses of only 1-4 percent.

4. Solar panel type

There are numerous types of photovoltaic solar panels available on the market. We distinguish three types of materials based on their technology: monocrystalline, polycrystalline, and amorphous. The installation’s performance will be affected by the model chosen:

  1. The yield of monocrystalline panels ranges between 18 and 23 percent.
  2. Polycrystalline panels have a yield of 14 to 17 percent.
  3. Amorphous panel yield: 8 to 12 percent

Although amorphous photovoltaic panels are less expensive than crystalline ones, they require a greater number of modules and more space to generate the same amount of electricity.

5. Situation geographically

Each province in Ireland receives a different amount of solar radiation, which has a direct impact on the amount of electricity that solar modules can generate. Locations with more hours of sunlight per year will require fewer panels than less sunny locations.

Using housing factors to calculate the number of solar panels

The type of home and its characteristics must be considered when calculating the number of solar panels required for our self-consumption system. The most important aspects are as follows:

1. Roof measurements

The solar panels have a surface area of about 1.5 – 2 m2. As a result, we must ensure that we have enough surface area on our roof to complete the installation. If we have a limited amount of space, it is best to look for higher power panels that allow us to produce the same amount of electricity in the smallest amount of space.

Solar panel dimensions and performance depending on its power:

PowerSizePerformance
200 – 250 W1.5 m 214 – 15.5%
250 – 300 W1.7 m 215.5 – 17%
300 – 350 W1.8 m 217 – 18%
350 – 400 W2 m 218 – 20%

2. Electricity usage

The size of the installation will be determined by the amount of electrical energy consumed per month. You can check your electricity bill to find out how much electricity you use. It will show you the electricity costs for the most recent period (1 or 2 months) as well as the total for the year.

The amount of energy consumed in a given time period is expressed in kWh.

3. Working hours at home

The amount of energy that we can consume will be determined by the hourly distribution of our electricity consumption. The maximum performance of the self-consumption system is obtained when electricity is consumed while the solar panels are in use, i.e. during daylight hours.

Who should be in charge of dimensioning my solar installation?

The sizing of a self-consumption system should be performed by a qualified technician who has the necessary knowledge to evaluate the number of solar panels that the house requires based on the energy needs and the house’s characteristics. It is preferable to be aware of the factors that influence; however, an extensive study must be conducted to ensure that the project can be completed without incident.

How do I request that a solar study be conducted in my home?

1. If you are considering switching to self-consumption, the first step is to request an indicative budget. To do so, you must provide a number of details in order for us to offer you a home and consumption-specific alternative. A utility bill is the most appropriate piece of information for making the most competitive offer possible.

2. Within 24 – 48 business hours, you will receive a proposal outlining your solar installation, how much it would cost, and how much you could save. If you find it appealing, you can request that a solar study be performed in your home in order to communicate the final price and learn more about your solar installation. This is what it is:

  • The number of solar panels needed
  • Where will the photovoltaic modules be placed? (in series, parallel or mixed)
  • The installation’s orientation and angle of inclination
  • Estimated self-consumed energy production Estimated surplus generation
  • Estimated amount of grid energy consumed
  • Estimated annual savings and payback period

How to install solar panels on roofs

There is a bit of hype right now about renewable energies, which are generated by the planet and nature itself, and they are a terrific alternative to traditional energies. They are unlimited, pure, and environmentally favorable energies.

Renewable energy sources include hydraulic, wind, solar, geothermal, tidal, biomass, and biogas.

Solar energy is without a doubt the most “cheap” for the user, since there is now a wide choice of equipment and solar panels at low rates that can cover any requirement, whatever it may be, thanks to the availability of full kits that are also expandable.

Because these solar panel kits are primarily aimed at single-family houses, they are frequently referred to as “self-consumption kits.”

But, before we go into this type of solar panel kit, let’s look at the major benefits of solar energy.

The Benefits of Solar Energy

  • It is a renewable and limitless source of energy.
  • It is considered a clean energy because of its low emissions and environmental sensitivity.
  • When compared to other sources of renewable energy, it is less expensive to install.
  • The cost of maintenance is very minimal because it is rarely required.
  • These facilities are extremely dependable and long-lasting. In fact, solar panels have a usable life of roughly 35 years assuming adequate maintenance is performed, which we have already stated is low.
  • It has global coverage, which means that the sun can reach every location on the planet, including the most remote and difficult-to-reach areas.
  • This form of energy is absolutely silently produced.

Solar panel installation

Solar panel system installation by expert companies is entirely usual. So we won’t get into it.

However, due to the continual advancement of technology and the manufacturing businesses’ insatiable search for individualized solutions for each potential customer, it is now possible for the user to “self-install” their solar panel system. This is a fantastic novelty.

The pre-wired kit solar panel systems, the clear instructions that come with them, and the manufacturer’s professional help to clear up any uncertainties during installation allow a DIY enthusiast to carry out the installation with complete confidence.

Kit and fixing system selection

Depending on where the solar panels will be mounted, one of two fastening systems will be used. We can select one of the following options:

  • Fixing on the ground.
  • On facades.
  • Fixing on flat roofs.
  • On sloping roofs.

The attaching and anchoring systems will also be determined by the surface, which can be concrete, tile, sheet metal, or another material.

Glass type selection

Solar panels are made of silicon cells, although there are monocrystalline and polycrystalline panels available. What are the distinctions between the two?

We could summarize the distinctions in four ways, greatly simplifying and in broad strokes:

Monocrystalline silicon is created using a slower heating process than polycrystalline, also known as multicrystalline silicon.

As a result, the energy cost of manufacturing is higher than in the later situation.

Monocrystalline silicon has a little higher efficiency than polycrystalline silicon.

The primary visual distinction between the two is that the first is black or dark gray, whilst the second is navy blue.

So, which one should I go with? Is monocrystalline preferable?

DO NOT DO IT. They have diverse characteristics, and each performs a certain function.

Installation with monocrystalline solar panels is advised for cold climates with frequent storms or fog, because this form of solar panel absorbs radiation better while enduring overheating poorly.

Polycrystalline solar panels, on the other hand, are suggested for installation in hot climates since they absorb heat more quickly and support overheating to a higher extent.

Microinverters or Inverters?

They are the facility’s beating heart. They transform the energy generated by the solar panels into alternating current, which is then directly consumed.

Despite their higher cost, Microinverters are without a doubt the best option. And there are various explanations for this:

They improve safety by lowering the chance of an electric arc while using alternating current.

With one-click fixation and connection, installation is simple and error-free.

Microinverters enable you to grow your solar panel installation at any time and without limit.

They offer the option of having the installation regularly monitored.

They maximize efficiency by functioning independently of one another. In other words, if a microinverter fails, the rest of the installation’s microinverters continue to function normally.

Finally, microinverters can generate up to 15% more energy than regular inverters.

Installation process for solar panels on roofs:

  1. The fittings, like the solar panel kit, comprise all of the components required for setup and functioning.
  2. They are square metal tubes that, when combined, produce a 15-degree slope to the solar panel.
  3. We can select between the standard kit or the wind protection kit. They are identical, with the exception of the latter having a metal plate that stops the wind from moving the solar panel from behind.
  4. This steel structure is installed by fastening it to the roof or by adding the necessary counterweights.
  5. You must ensure that the installation is securely fastened in some way.
  6. If the latter is crucial, so is the location and orientation of the solar panels for best performance and energy output.
  7. In terms of microinverter installation, each pair of solar panels has a microinverter installed beneath them.

As previously said, its installation is as simple as a single click.

7 reasons to put solar panels on your roof:

Solar is the most widely used renewable energy source for distributed generation around the world.

Aside from being the most common, photovoltaic systems have various advantages that make them the ideal alternative.

  1. Durability: A solar panel has a normal lifespan of at least 25 years even when exposed to the elements on the roof. The efficiency loss in the conversion of light into energy is minor, and the major manufacturers guarantee 80 percent generation by the end of this period. A module with a life expectancy of up to 25 years will yield at least 80% of the energy it produced in the start. The photovoltaic inverter, the other critical component of the system, has a minimum usable life of 15 years. It can be extended a little farther with proper maintenance.
  2. Minimal maintenance: Despite the fact that the system operates 24 hours a day, photovoltaic systems require very little maintenance. The most important one is cleaning the plates, which you can do yourself. However, this is only if they are extremely dirty, as they feature a non-stick layer that inhibits dirt collection. In the case of dust, precipitation removes it. Cleaning excess debris or bird droppings is simple, requiring simply a jet of water and a soft bristle broom. We’ll have to maintain the electrical system as well, but considerably less regularly. Once a year is sufficient to ensure that the system generation is optimized.
  3. Weatherproofing: These systems are built with the appropriate physical protection in mind. Photovoltaic panels are strong enough to survive the impact of huge hail balls. Everything is being done to ensure that they continue to function throughout their extended lives.
  4. An increase in the value of the property: Another significant benefit for people who install residential solar energy is the increased value of their home. A home that generates its own electricity should be more valuable than one that does not. As a result, if you decide to rent or sell your home after installing a solar system, you will be able to get a greater price for it.
  5. Electricity cost: Having a solar system in your home means that your electricity bill is not inflated. You will be shielded against price rises if you install a photovoltaic system.
  6. There is a quick return on investment: Installing a solar energy system is a significant financial investment. And the payback period for solar energy investment is highly appealing. Although the cost of your installation and the cost of electricity in your area will vary, I can tell you that you will recoup your investment before the useful life of your roof tiles expires, allowing you to enjoy a few years of free electricity.
  7. Electricity bill reduction: And, of course, this return on investment is only feasible because of the most significant benefit of these systems: savings of up to 95 percent on the electricity bill. A photovoltaic system that is connected to the grid (On-Grid) can be constructed to generate all of the electricity used in a home. As a result, you no longer have to pay for the energy you consumed from the network and will just have to pay the minimal fee.

There are several valid reasons to enhance your heating system with solar thermal energy. Throughout this piece, I will reveal the mysteries of solar panel heating and all of its benefits.

Many heating systems that are more than 25 years old are still in use. Owners are sometimes ignorant of the financial and energy waste that their outdated facility represents. This, of course, results in money and energy losses, but it also has an impact on the climate through wasteful CO2 emissions and adds to global warming.

Conserve energy and lower your utility bill

End users can save up to 35% on energy by immediately upgrading these extremely efficient condensing boiler systems in conjunction with solar technology.

Conserve resources: The use of free solar energy as a supplement to heating and domestic hot water is uncommon. It is critical to consider the combination of heating and solar energy while upgrading a system. It will be free as long as we do not use it in tandem or surpass 10kwh.

Significant cost savings: Solar energy is a significant source of savings for the generation of sanitary hot water. Solar panels in conjunction with a hot water tank, particularly during the summer months, are a highly appealing alternative to running the boiler.

During transitional seasons, when the sun is heating the boiler, the boiler can often be left off. A solar installation can meet up to 60% of a home’s hot water requirements.

Hot water for heating with solar energy

Solar systems are excellent for producing heating and hot water. With the availability of solar energy, your investment will pay for itself after only a few years of use.

The system you must put together is a closed circuit system in which water is heated and passed via thermal emitting radiators.

The bivalent solar hot water tank is the focal point of this system. When there is enough sunlight, the solar fluid heats the water in the hot water cylinder via an exchange surface. If the temperature in the water sampling falls, for example, during a bath or shower, the boiler activates a second circuit to offer additional warmth.

Solar power plant for the generation of hot water for the heating circuit

The heat transfer medium can also be used to heat water in addition to producing hot water.

A solar water heater makes use of the available solar energy. Solar energy is a long-lasting source that helps to achieve energy independence. The production and usage of a solar water heater produces relatively little waste and greenhouse gas emissions. As a result, solar thermal energy is a clean and ecologically favorable energy source, allowing for the creation of an environmentally friendly solar water heater.

The amount of hot water that a solar water heater can produce is determined by the quality of the solar panels and the surface area of the solar collectors. The size of the hot water tank is determined by the needs of the household.

These two aspects are determined by your requirements and the available area:

Ecological heating:

If there is one factor that is considered today when building a heating system within a home, it is the fact that it is both economically and environmentally sustainable.

As a result, today we will discuss two heating systems that we believe are the most environmentally friendly at the moment.

On the one hand, we will discuss solar heating, which is based on the installation of solar panels, and on the other hand, we will discuss biomass heating, which is nothing more than an air conditioning system that uses biomass as fuel.

Aspects of solar heating to consider:

Although I go into further detail in the article on heating using solar panels, certain remarks are useful.

When we talk about a heating system based on solar panels, we’re talking about a system that is self-sufficient in terms of both economics and energy.

And it is that, if we run out of economic capacity to obtain fuel, we will always have at our disposal a fuel that is currently infinite, and that is none other than the Sun.

Furthermore, it must be stated that it is a completely pure and sustainable energy. Solar energy is, unsurprisingly, one of the most cutting-edge and avant-garde renewable energies on the market. However, in keeping with reality, it should be noted that its installation is not inexpensive. A barrier that we can overcome if we take advantage of the numerous subsidies available in several places in Ireland.

What should we consider when it comes to biomass?

We can, however, have a system that employs biomass as a source of combustion. This type of biomass boiler is based on and distinguished by the use of a particularly environmentally friendly and inexpensive fuel. We will not be able to use the almond shell, the olive pit, some small ones, and some small tubillones called pellets in vain. A fuel that we will be able to obtain in nature itself and that has been in full swing for some years already.

In exchange, like with solar energy heating, we will have boilers that are not precisely inexpensive. However, an intriguing trend has been discovered, which is the increase in the acquisition of this sort of device. An increase in purchases that will have no effect other than to cut costs and allow these systems to be obtained for relatively little money over time.

DIY Solar Panels: Build Your Own At Home

DIY Solar Panels

Getting our gas or electricity cost reduced while contributing to less greenhouse gas emissions into the atmosphere is doable and as simple as sipping a soft drink or several, because we will need a few aluminum cans to make our homemade solar panel.

After gathering all of the cans, the first step is to hold them at the base and then glue them all together with a high-temperature-resistant silicone. We must not forget that when the cans are exposed to the sun, hot air will circulate inside them.

We install many columns of perforated cans in a wooden box, but always leave a chamber at the beginning and end of each column so that the air inlet and outlet are not hindered. We will paint all of the cans black (which will also help it get hotter) and the wooden frame white, and we will insulate the heater by covering the entire front of the DIY solar panel with plexiglass (polycarbonate / acrylic).

We will already have our homemade solar panel in which we will introduce cold air through one of the chambers and when leaving the other, after passing through the hot cans, it will return to us with a temperature that will allow us to easily maintain the 20 or 21oC centigrade in the stay of our department.

Another creative option to make our own solar panel is to use plastic bottles, which we will paint black once they are clean and dried. We can almost finish it if we fill them three-quarters full of water, compress them so that the water contacts the cap, and place them in a cardboard box with the bottom and interior sides coated with aluminum foil. It will be sufficient to position the box towards the south with an inclination of around 45 percent with respect to the ground, and we will have hot water for your enjoyment within 2 to 5 hours.

If, on the other hand, we want a more professional-looking handmade solar panel, we can acquire it, albeit we will need to be more adept DIY enthusiasts. The solar cells will be the primary component of these panels, since we will require approximately 36 of these cells to generate approximately 12 volts, adding them as if they were batteries (alternating positive and negative poles).

Using epoxy glue, wire, and a soldering iron, we will assemble all of the cells on a wooden or acrylic panel and protect them with plexiglass, similar to that used to preserve cans. We’ll be almost finished with our handmade solar panel, all that remains is to connect the cells to a battery with a regulator in between to prevent overcharging. The final stage in using electricity in our gadgets will be to transfer the power through an inverter, which will convert the 12 volts of direct current to the 120 volts of alternating current used in a typical house.

Professional or DIY Solar Installation?

When you decide to install solar energy in your home, you must determine whether to hire a professional or do it yourself. But should you pay for professional installation or go the DIY route and install the system yourself? Consider the benefits and drawbacks of both DIY and professional solar installation before making a decision.

Many individuals are unaware that they can build their own solar panel system. This installation approach is not without its difficulties, but it also has some significant advantages.

What are the benefits of doing it yourself?

Lower costs: Solar kits are less expensive than employing a solar energy firm, and you will no longer have to pay for a professional to install your system. Professionally installed solar panels can cost $ 7 to $ 9 per watt, which means a 5 kilowatt (kW) system might cost $ 35,000 to $ 45,000 before incentives.

Because you won’t have to pay installation fees if you install your own system, you can keep your prices as low as $ 3 per watt. Those reductions could reduce the overall cost of a 5 kW system to $ 15,000 or less, depending on the make and quality of the panel.

Simple access: Because solar power has become a popular energy source for households, you can buy a solar home kit online from a wholesaler like Amazon.

If you hire a professional installer, you may have to wait several weeks for the equipment to arrive and plan an installation date. When you install the matrix yourself, you can do so whenever you wish.

What are the disadvantages of DIY solar installation?

Setup is complicated: While there are many solar panel installation tutorials available online, you will still need to be skilled with building and electrical work to effectively install a home solar array.

In addition to sizing your system and acquiring equipment, you will need to properly connect the panels and inverter, and then wire the inverter to a battery or meter. There is a risk of fire or electric shock if you are not comfortable working with electricity.

Scope is limited: Most solar kits are intended for off-grid use, and utility companies sometimes refuse to enable homeowners to connect a solar array to the grid without the proper permits and professional clearance.

Going off the grid can be difficult for the average homeowner who still wants to use their utility company’s electricity. If you are not linked to the grid, you must guarantee that your solar panels are always providing enough electricity to fulfill your demands.

DIY solar installation is a wonderful alternative for those who wish to power a location outside of their home, such as a barn, shed, or motorhome, because these facilities are already off-grid and do not require as much electricity as a home.

DIY solar installation may also be the ideal alternative for people who currently live off-grid and are confident in their ability to figure out the process on their own.

What are the benefits of doing it by a professional?

More knowledge: For years, some of the larger solar firms have been installing solar house systems. You can feel more confident if you use a professional firm because many jurisdictions require installers to be licensed and meet predetermined standards to install solar panels.

Furthermore, because most established firms have dealt with hundreds of customers, they can assist you in determining how much solar power your home requires and how much solar power you can obtain prior to installation.

Premium materials and assurances: While professional installation is more expensive than a DIY kit, in most cases you pay for superior quality – a significant issue given that decent solar panel systems can endure for decades.

Solar installers can frequently purchase equipment from merchants that they do not sell to the general public, giving them access to higher-quality panels and supplies that a Home Depot kit cannot provide.

Some solar companies even have their own panel technology that vastly outperforms industry norms. Furthermore, most competent installers offer warranties on their work, so any future repairs may be covered.

Professional installation has some significant advantages, but it also has some disadvantages.

What are the disadvantages of doing it by a professional?

More paperwork and red tape: Before a professional installs your system, you will be required to complete a significant amount of documentation. Before work can begin, all necessary permissions and applications must be completed and properly filed.

While the company will assist you with this process, it may delay the timetable, resulting in a longer period for the system to be operational.

In addition, if you are denied a permit or your utility company has tight laws about solar panels, your installation options may be limited.

Higher upfront expenses: As previously stated, the costs of professional solar installation often outweigh the costs of DIY home solar kits.

Many professional solar firms want upfront payment, so you’ll either need cash or apply for a solar loan. Many people cannot afford to pay between $ 35,000 and $ 45,000 in cash, and some may not want to apply for, or deal with, the additional interest on a loan.

While professional solar installation is more expensive, it makes more sense for the typical homeowner who does their research online. You won’t have to worry about repairing the damage yourself with quality materials and warranties, and you’ll feel more confident knowing that your system is properly built and approved by your utility company.

You can better pick which installation method is ideal for your case now that you’ve read the advantages and downsides of each. Next, look into the firm or brand of system that best meets your budget and power requirements.

3 reasons to install your DIY solar kit right away (instead of later)

If you follow industry news, it may appear that the delay is justified. After all, interesting new solar technology developments are always making headlines. Should you postpone your home PV installation now that more efficient PV components are on the horizon?

However, when many essential facts are considered, it is easy to see why waiting may not be the best option.

New solar technology will be available soon: Scientists all over the world are always attempting to enhance photovoltaic components, and their findings could eventually lead to the development of more efficient solar panels.

The issue is that new house PV technologies take years to develop and millions of dollars to commercialize. Many seemingly interesting innovations never make it out of the lab.

So, while new PV technologies may sound appealing, waiting for them to work is not a viable option.

Right now, a DIY solar kit can effectively save your home: Today’s DIY solar panel kits include top-of-the-line photovoltaic components that are backed by industry-standard warranties.

This technology has been tried and tested and proven to function. If you go solar now, your PV array will give you decades of free electricity with little to no maintenance.

Because new technologies are not tested over time, they may not function as planned. Although laboratory results are promising, no one knows how photovoltaic components will perform in a few years.

Do you want to be a guinea pig when you invest in your energy independence? Install a DIY solar panel kit today and you won’t have to worry about the long-term viability and efficacy of your house PV installation.

Install a DIY Solar Kit and your savings will begin immediately: Let us now discuss money. Solar panels and photovoltaic home equipment prices are unlikely to fall considerably in the coming years. Manufacturing has already been optimized, thus costs cannot be reduced further.

Furthermore, today’s financial advantages for installing a home PV system can reduce your investment expenses by thousands of dollars. The federal solar tax credit only provides a 30% refund, however various state and local rebates, tax credits, and gifts significantly improve your savings.

However, these lucrative advantages can vanish at any time. The federal solar tax credit will expire in 2021, but it could be sooner. Many state and local PV incentives are already on their way out.

Install a DIY solar panel kit today, and you won’t lose out on any of these opportunities to reduce the cost of your PV investment. Furthermore, you will experience immediate savings because your monthly utility expenses will be significantly cut or possibly eliminated.

How do solar panels work

The operation of solar panels is not as difficult as it may appear. In this essay, we will explain how the plates function and which are the best for self-consumption.

Solar energy generation in Ireland has expanded in recent years, both in major solar parks and in tiny self-consumption facilities. For a variety of reasons, more and more homeowners are opting for photovoltaic panel installations. From the cost savings on the electricity bill to the environmental responsibility that it includes, it is a win-win situation.

If you are thinking about making the switch to renewable energy, it is important to understand how the facilities work.

How do photovoltaic solar panels work?

The operation of solar panels is primarily dependent on the photovoltaic solar cell, which directly converts solar energy into electrical energy via photoelectric energy. Photovoltaic generation is the ability of some materials (for example, silicon) to generate electrical current when exposed to sun radiation. It happens when sunlight’s energy (photons) “releases” electrons, resulting in a flow of electrical energy.

A solar panel or module is made up of a series of photovoltaic cells, which are layers of silicon “doped” with phosphorus and boron that generate an electrical charge as a result of solar radiation and are commonly serialized in a module (or panel) so that the voltage is set to a usable DC (direct current) system.

By connecting to an inverter, this energy will be converted into AC (alternating current), allowing the solar panels to supply the energy you use during the day.

It should be emphasized that the voltage produced by solar cells is always relatively regular and linear; nevertheless, the current produced is dependent on the intensity of the light. As a result, the performance of a solar panel is heavily dependent on how intense the light received is, which varies based on the time of day and year.

How do you calculate the power of a solar panel?

To understand how solar panels function, you must first grasp how the power of a module is computed. When it comes to measuring or estimating the performance of the panels, watts peak (Wp) is the unit of measurement used in solar modules. This metric is used as a standard for measuring the performance of solar panels and making comparisons between them. Because the amount of sunlight shining on the panels varies according to the time of day and year, the current generated fluctuates significantly, making measurement difficult. As a solution to this problem, peak watts (Wp) are measured, which indicate the performance delivered by the panels under conventional solar radiation and temperature conditions.

This means that when sizing a photovoltaic installation, it is critical to consider how many peak watts (Wp) must be installed in order to achieve the highest potential self-consumption capacity.

When assessing the size and performance of an installation at Clover Energy Systems, we consider all of these criteria, including your geographical location as well as the direction and angle of the roof. By inputting your address and then assessing your consumption and expectations, we can determine the size of the installation that best meets your needs.

Characteristics and taxonomy

Much has changed in the solar business since Einstein discovered the photoelectric phenomenon in 1905, and Bell’s laboratories produced the first silicon panel in 1954.

Solar modules are now made from more modern materials and are significantly more efficient. In this approach, it has multiplied its performance sufficiently to establish itself as a profitable energy alternative. Having said that, the entire process that occurs inside solar cells when the sun shines remains essentially subject to the same effect described by Einstein in 1905.

When comparing silicon-based solar panels, there are primarily three types to consider: amorphous, polycrystalline, and monocrystalline. These silicon panels perform the same purpose in a photovoltaic system, catching the sun’s energy and converting it to electricity. However, when it comes to evaluating how each of these solar panels works and how well they function, there are certain differences between these two technologies, which are primarily centered on the manufacturing process and the type of silicon cell contained in the solar plate.

Solar panels made of amorphous materials

Amorphous panels, which are becoming less popular, are distinguished by the lack of a defined structure and a significant loss of efficiency during the initial months of operation.

Solar panels made of polycrystalline crystals

Polycrystalline solar panels are differentiated by their blueness due to their composition of variously orientated crystals. This manufacturing process has the advantage of being less expensive, but it also produces a less efficient product.

Solar panels with a single crystal

Monocrystalline modules are often thought to be of higher grade. The cells that make up the panel are composed of a single, high-purity silicon crystal that has been cemented at a homogenous temperature. This increases the efficiency and performance of the panel by allowing electrons to move more freely. While the manufacturing process is slightly more expensive, the modules are more efficient and perform better. They are generally thought to be of higher quality.

Which solar panels are the best?

Monocrystalline solar panels are the most commonly recommended. Amorphous plates are becoming outdated due to their rapid loss of efficiency. Polycrystalline panels, on the other hand, offer only a modest price benefit due to the previously described less expensive manufacturing procedure.

The key benefits of monocrystalline solar panels

  • The main advantage is a higher degree of efficiency (around 5% more), they perform better in surroundings with less light exposure, foggy days, or simply in locations where there is less daylight.
  • On the other hand, it has a slightly higher performance, which means that monocrystalline solar panels deliver more electricity for the same installed area.
  • They tolerate heat better, at high temperatures, panels lose efficiency; monocrystalline panels tolerate heat better, which is a benefit in the face of high summer temperatures.
  • Finally, the modules are black and so aesthetically fit better with the roofs.

Qualities and Components

In addition to silicon cells, solar panels contain a glass frame that provides protection and durability for proper operation.

The panel contains an insulation layer and a security foil inside the glass to guard against heat dissipation and humidity inside the module. Proper insulation is critical because it protects the panel from temperature variations, which diminish efficiency and performance.

Some current solar panels use a technique known as PERC. It is an anti-reflective coating that improves the module’s performance in low-light conditions (cloudy days, morning, and dusk), allowing the silicon cells to obtain maximum sunlight exposure and giving you extra self-consumption hours.

Furthermore, by acting as a reflecting layer, they keep the module from overheating and hence improve its performance by keeping the panel’s temperature coefficient steady. Because all solar modules in the photovoltaic sector go through the same production process, we at Clover Energy Systems understand the importance of installing modules with high-quality components. As a result, we only work with TIER 1 certified brands that use monocrystalline modules and PERC technology.
