How is Solar Energy Stored?

Solar energy has proven to be an effective solution for the use of renewable energies, becoming an option that is increasingly adaptable to various energy storage systems. But when we talk about these systems, we don’t just mean solar panels. We also refer to solar batteries.

In October 2014, a group of biochemists from the University of Ohio would have solved the loss of electrical energy caused by electrons traveling from a solar cell to a battery, allowing them to create a system capable of storing 100 percent of solar energy in a battery, a system known as a solar battery.


They are a system for retaining and distributing solar-generated electrical energy. They contain at least one pair of electrochemical cells, each with a negative and a positive electrode, designed to convert so-called chemical type energy – from solar radiation – into electrical energy.

These batteries work in tandem with solar panels, also known as solar modules, which are responsible for capturing photovoltaic solar energy and converting it to electrical energy. When solar panels collect more energy than they can provide at the same time, the excess is stored in solar batteries.

As a result, the batteries can be used as backup energy when the solar panels do not receive solar radiation – either due to cloud cover or at night – and thus do not generate electricity. Furthermore, solar batteries will provide more electrical energy, allowing for the use of more electrical equipment.


Solar batteries come in a wide range of sizes and shapes, with the main differences being the technology used in their production and, on the other hand, the type of cycle. They are distinguished by the following characteristics:

A. Batteries based on their cycle life

  • Low Cycle Batteries: When it comes to capturing energy, these batteries have been specifically designed for low-demanding routines. That is, they are ideal for supplying small amounts of energy for short periods of time. They do not tolerate high percentage discharges, specifically those greater than 80%, because they significantly reduce their useful life.
  • Deep cycle batteries: Unlike the previous type, deep cycle batteries have a high resistance to discharges of up to 80%. As a result, they are a cost-effective option that is in high demand.

B. In accordance with its technology

  • Liquid batteries: While they are not the most resistant to low temperatures, they are inexpensive and have an acceptable quality margin. Liquids are classified into two types: sealed and open. The sealed ones have valves that allow them to exchange liquids, whereas the open ones have a movable cover that allows them to do so.
  • AGM batteries: From the start, this model stands out for its high resistance, and as a result, its useful life is among the longest among its peers. It also has a deep cycle, so it can withstand high discharges. They contain glass fibers that absorb acid, and the majority of these models include a regulated valve. Because of these features, it is the most expensive model.
  • Lead-acid batteries: This model has the best quality-price ratio. In this regard, they offer a favorable yield of up to 80% – 95%, respectively. However, preventive maintenance is essential in order to extend their life. They must, in particular, be charged 100 percent after each cycle to prevent them from shutting down due to self-discharge.


It is critical to understand some aspects of battery quality and performance, as they will be critical in identifying the best solar batteries based on the needs identified:

A. Capacity to carry a load

It is the number of amps (A) that a battery can store as part of its power reserve. It is necessary to comprehend this aspect in order to select a solar battery with sufficient reserve to cover the required electrical energy backup.

B. Self-discharge proclivity

Many batteries discharge if they are not used frequently, and solar batteries are no exception. Higher quality models are less likely to have this issue; however, it is critical to evaluate this feature prior to purchase.

C. The load’s energy balance

The energy required to charge a battery is not exactly equal to its total reserve. Some batteries reserve less energy than is invested in their charge, resulting in a negative energy balance. Charging efficiency, as a factor to be evaluated at this point, should be as close to 100% as possible.

Is it possible to generate solar energy in the winter?

Is it possible to generate solar energy in the winter

Is it possible to generate solar energy in the winter?

Solar energy is sustained by solar radiation, which is why it stands out for its high autonomy capacity as an energy source for various home or industrial technologies. However, it is believed that the winter season will significantly limit their autonomy. In that case, is it worthwhile to use solar panels for the home?

Summer and spring are most likely the best times to obtain and use solar energy. The arrival of the cold season, on the other hand, has the potential to completely change the picture. Is it possible to obtain solar energy during the winter? We will now address this critical question by emphasizing a few key points.


Yes, solar panels can be used throughout the year. In reality, the real issue is its ability to function in cold temperatures. The correct question is, will solar panels produce the same amount of energy in the winter?

No. The generation of energy obtained from the radiation captured by solar panels has decreased noticeably. However, it should be noted that this drop is not due to a lack of heat – a result of low temperatures – but rather to a lack of sunlight specifically.

Capturing the electromagnetic waves of solar radiation yields energy. Radiation levels fall when the sky is cloudy. This phenomenon will cause a change in energy production whether you have solar panels for your home or solar panels for a pumping system.


With these considerations, it has not ceased to be a profitable option. Solar panels for homes, for example, can adapt to winter conditions and, despite not matching the same levels of energy production, can provide good value.

Remember that it is not about high temperatures, but rather about the reception of solar radiation, which, in conjunction with an adjustment set in the mechanism of the solar panels for home – and of any other type – will allow us to keep it in working order.


It entails assessing a number of techniques that will effectively optimize the work of solar panels for the home. These recommendations, however, can be applied to another type of solar energy installation. The following applications can improve the performance of a solar panel system in this regard:

A. Choose a strategic location.

The first step in obtaining good performance from home solar panels is to choose the best location in terms of how they are exposed to the sun’s rays. Most of the time, its orientation is determined by the seasons of summer and autumn, so the arrival of winter is detrimental.

The plates’ orientation relative to the sun must be as vertical as possible in order to capture the greatest amount of photovoltaic energy. This should be planned by considering all seasons of the year, not just autumn and summer, as is more common among users.

B. Use snow-resistant plates.

In the event of snowfall, the plates can withstand a certain amount and continue to function. This can be enhanced further if they are placed on an incline, allowing snow to slide off the plates.

It is always advisable to monitor the slabs on a daily basis, manually moving the snow that remains on its surface if necessary. However, by taking the previously mentioned precautions, the snow will not become a hindrance to its proper operation.

C. Maintenance as a preventative measure

The wind can also be a detriment to residential solar panels. It is possible that if it attacks the installation from the dorsal end, its stability, and thus its operation, will be jeopardized.

As a result, it is critical to perform preventive maintenance work, where it is possible to ensure that its position has been maintained since installation and that the plate orientation remains constant.


Solar panels for homes can withstand cold temperatures and provide energy via solar radiation. The key is to optimize these teams so that they can maintain their operability in the face of the characteristics of all seasons of the year, not just autumn and summer.

By accomplishing this, there will be no reason to negatively impact obtaining energy from the sun’s rays. As a result, whether they are solar panels for homes or industrial facilities, our solar modules will continue to supply energy to the appropriate equipment.

How should the solar panels be oriented?

How should the solar panels be oriented

How should the solar panels be oriented?

Solar panels are an intriguing alternative energy source. Its use is becoming more common, which raises hundreds of questions about its purchase. One of these inquires whether it is worthwhile to purchase low-cost solar panels in Ireland for a system that will operate for long periods of time and in open areas exposed to various weather conditions.

To answer this question, it is necessary to explain several points, the main goal of which is to guide the owner in optimizing the performance of their plates. The first point will be to understand how the solar panels should be oriented, which will allow you to finally understand whether or not the performance of your solar system will be affected by the purchase of cheap solar panels.


Assume there is a percentage range that explains how solar energy is obtained. The higher it is, the more energy is captured; the lower it is, the less energy is obtained through radiation. The percentage of energy obtained by the solar panels is determined by their orientation.

A poor orientation will degrade the performance of the plates, even resulting in losses. As a result, whether we are talking about cheap solar panels or the most expensive range, the inclination plays a critical role in the use of a solar energy system.

However, not everything is oriented. Because there is a significant difference between orientation and inclination, these two factors must be considered when installing either cheap homemade or industrial solar panels.

The inclination refers to the relative angle between the solar panels and the sun, which has a significant impact on energy generation. In short, both the orientation and the inclination of the plates must be adjusted. In this explanation, we will focus specifically on the orientation-.


Typically, homeowners do not consider the possibility of shadows affecting solar panels. As a result, facilities are found near trees or buildings that, at some point during the day, reduce the amount of radiation reaching the solar panels.

Even low-cost solar panels have diodes that allow you to control the effects of shadows. However, there is a discernible effect on the performance of the plates, specifically on the amount of energy they obtain. It is critical to choose a location where the plates will not be affected by shadows.


In short, the orientation should point towards the extreme south, where the most radiation can be captured. In fact, where is it? Changing the orientation of the plates will also improve the results as they approach the south.

Because the energy harvesting values are unlikely to be absolute, solar energy capture will never be perfect. This is because the location is not a variable that can be controlled impartially at the convenience of the solar energy system, at least in most cases.

The greater the south orientation, the better the performance of the plates, especially since the peak of solar radiation coincides with this extreme at noon, providing a significant use during this hourly block. In this regard, the recommendation is to point it as far south as possible.


From the most expensive plates to the cheapest solar panels, they can all provide the best results if the owner is able to properly control their location, orientation, and inclination. In this sense, it will entail correctly and constantly evaluating whether or not these variables favor the plates.

Because climatic conditions are changing, it is necessary to monitor the plates to avoid any damage, especially during the winter season, when snow can remain attached to the plates. Given this, a good incline could rule out this possibility; in fact, a good incline will cause the snow to move on its own.

If the owner does not address the cheap solar panel installation conditions (orientation, location, and inclination), he will be unable to enjoy favorable results, assuming a significant loss in this energy source. However, this is not the end of the story, as poor weather conditions may end up damaging the solar cells on the plate.

The health of cheap solar panels has come to rely on the terms of their contract, which is yet another factor to consider when evaluating this point. This will allow for an intelligent installation based on parameters that favor your energy levels from the start.

Why is installing solar panels cheaper and more profitable than 10 years ago in Ireland?

Why is installing solar panels cheaper and more profitable than 10 years ago

Why is installing solar panels cheaper and more profitable than 10 years ago in Ireland?

Renewable energy has been widely characterized as one of the market’s most expensive options. Solar panel, in particular, has higher equipment and installation costs than traditional energy. However, cheap solar panels are now available. What makes this possible?

Many people have noticed a significant decrease in the cost of solar energy, which has resulted in an increase in the number of owners who put their trust in these systems. This is due to a number of factors that, when combined, have resulted in a more affordable system for users.

Next, we’ll look at what these factors are so we can understand why it’s now possible to find cheap solar panels to install in our homes.


Before delving into the factors, it is important to note that cheap solar panels have registered an 80 percent surplus in cost reduction, resulting in a significant difference in the prices of solar kits. Those 290 euros MWh would now be reduced to 33 euros, making solar energy one of the most cost-effective options.

1. Solar system costs:

Renewable energy systems based on solar energy have historically been characterized, among other things, as being incredibly expensive to build. When compared to the construction of thermal power plants, the construction of a solar plant typically requires a difference of 220 percent in terms of investment.

In theory, this is explained by the operating costs of renewable systems. Well, whether we’re talking about cheap solar panels or wind systems, we know that the operating costs of renewable systems are lower to a large extent because they don’t require a fuel system to function.

Solar panels do not require the same level of maintenance as thermal plants and, as a result, do not represent a significant long-term cost, because they can operate autonomously by generating their own energy (fuel).

2. Benefits scheme:

The advantages of renewable energy systems are undeniable. As a result, the Spanish government has largely funded the purchase of low-cost solar panels. This is done to encourage the use of this technology, which greatly benefits environmental protection and the use of renewable energy.

Owners can obtain these systems for only 25% of the required cost, while still enjoying external coverage of up to 75% depending on certain conditions (depending on each autonomous government). As a result, the price is more affordable in this regard.

3. Strong self-consumption:

Self-consumption of low-cost solar panels was not the most significant ten years ago in terms of profitability. In fact, the first solar systems could only be used as a supplement in different power plants. However, this has changed significantly, altering the role they play in the owners’ homes.

Currently, low-cost solar panels can manage more than half of the energy required in a home. In this regard, they have become significantly profitable in terms of energy savings, and thus a purchase of significant benefits to deal with the electricity bill.

4. Advanced Photovoltaic technology:

In terms of production, photovoltaic equipment has seen a significant improvement. Specifically, in the materials used and their increasingly compact, but efficient, designs. A balance that would result in a lower cost in terms of accessibility.

In practice, each solar panel would be able to work twice as long as its price was adjusted, resulting in a highly profitable offer for the owner, quickly positioning cheap solar panels.

5. Household-specific systems:

While there are large-scale solar systems designed for the home, homeowners can also enjoy solar kits as a compact but profitable offering. It is a collection of tools that will allow you to install and enjoy solar energy equipment in the comfort of your own home.

This system is simple enough for the owner to install and inexpensive enough to buy. A solution to the use and acquisition of this technology, presenting the buyer with a practically essential offer.


Renewable energy has made significant progress in two key areas: price and performance. As a result, its profitability skyrocketed, making it one of the first and fastest-growing options today.

Solar energy in 2021

Solar energy set a new record in Ireland on July 7, 2021. According to the data gathered, nearly 67000 solar panels have been installed in Ireland. In other words, this figure accounts for 30% of total electricity demand.

Ireland is entering a new era in which it will prioritize critical factors such as profitability, leadership, and consolidation.

These more ecological alternatives to energy consumption already existed; however, as a result of the current situation with the pandemic, many people are increasingly participating in the reduction of carbon footprints, with the goal of compensating for CO2 levels and leading a more responsible life and consumption.

The most affordable renewable energy you must need:

Ireland has entered the solar panel manufacturing industry. Because of the current state of the planet, the government has implemented new policies to change the way people consume in this country and thus contribute to the reduction of the carbon footprint.

Photovoltaic solar energy is currently the most affordable renewable energy source. This could become the country’s primary source of energy. With rising electricity prices, the use of photovoltaic energy is increasing in single-family homes and buildings.

Furthermore, we can rely on a variety of aids and subsidies to provide citizens with greater convenience when installing this type of energy in their homes. The conditions differ depending on the municipality in which you live.

According to the data, a 27 percent year-on-year increase is expected in 2021. Despite the increase in long-term module prices, 185 GW of new solar energy is expected to be installed globally. as well as increased transportation costs.

Various factors to consider when purchasing a solar panel:

In addition to the installation of solar panels or self-consumption kits, the presence of devices that support the proper operation of photovoltaic energy and thus good energy savings in the home must be considered.

  • The storage battery is required to store all of the energy generated by solar panels.
  • Photovoltaic regulators are in charge of constantly monitoring the battery charge status in order to ensure optimal filling. It also extends its useful life in this way.
  • It is critical to double-check the contracted power in case it needs to be changed. It is critical to consider the power required to complete this installation and, as a result, to have adequate power based on the home’s consumption.
  • If you need a lot of energy, invest in a lithium battery. That is to say, these types of batteries are essential in homes or buildings where a high level of energy autonomy is required, even at night or on days with low radiation.
