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.
