Solar panels

In recent years,the use of solar panels has grown considerably, which is not surprising if we take into account the many advantages they offer.

We are a company that installs solar panels and here we will explain what solar panels are.The different types that exist and the most important aspects to consider when choosing a solar panel. Are you going to miss it?

What are solar panels?

Solar panels, also known as solar energy, can be defined as devices that harness the sun’s energy to generate electricity or heat.

One of the particularities of the solar panel is that it can be used in industrial complexes, as well as for personal use.

In fact, the production of solar panels for private homes has improved significantly, so that we can bet on this format in all types of homes, even if they are somewhat remote.

Solar panels: How do they produce electricity?

Many people wonder how it is possible for a solar panel to produce electricity.

The first thing to know is that these plates are composed of photovoltaic cells and that, in turn, these are made of semiconductor materialsand coated with a transparent glass that allows solar radiation to pass through.

In this way, when solar energy is absorbed, the photoelectric cells transform that energy into direct current.

Finally, by means of the inverter, this energy is transformed into alternating current that allows us to enjoy electricity, being a very simple process and that makes it one of the most recommendable alternatives that we have within our reach.

Let us remember that it is not only an environmentally friendly energy, but also more economical than conventional energy.

Important considerations when choosing a solar panel

If you are thinking of opting for solar panels, you should consider a series of aspects that will be key to choosing the type of solar panel that best suits your needs.

We start by talking about the different possibilities we have in terms of technology, as we can find panels with polycrystalline, monocrystalline or amorphous cells. Today, the most popular and recommended solution is monocrystalline cells.

The Solar panel power is one of the most important aspects to consider. The possibilities we have in terms of power are infinite, being advisable to consult with a specialist the option that best suits our needs.

It is worth mentioning the efficiency as another key detail when choosing a solar panel. It is estimated that the It is true that there are panels that offer a higher percentage of efficiency, although the price is higher and they have larger dimensions.

If you plan to purchase a solar panel, you should study the temperature coefficient offered by each model.

It is a detail that indicates the energy losses of the panel due to the temperature increase, being an essential aspect especially in those areas where the temperature is high.

Finally, we cannot conclude this list of aspects that should be considered before buying a solar panel without mentioning the warranty, with the particularity that solar panels include both the product warranty and the production warranty.

In the case of product warranty, it is necessary to opt for a panel that offers at least 15 years of warranty, while for production warranty it is important that the manufacturer offers a yield between 80% and 90%.

Solar panels: how are they manufactured?

The solar panels are composed of a group of solar cells which are connected to each other and together achieve the ideal voltage for them to work properly. Next, we will learn about the different components of a solar panel.

The anti-reflective glass cover is one of the most noticeable parts of a solar panel, with qualities that allow a sunlight transmission of at least 90%.

Moreover, Plexiglas laminates offer us the ideal stability against chemical and atmospheric agents.

The steel frame is another component that plays an important role in the manufacture of a solar panel, being essential that it is made of stainless steel to withstand the rain, while its function is to join all the parts of the panel.

The solar cells, which are placed in both columns and rows, are indispensable in the manufacturing process of a solar panel.

They are made of materials that stand out for their good electrical conductivity, being the most important one the span one of the most recommended materials.

In addition, the solar cells rest on the base plate and are held together by silicon, which is an ideal material for preventing water seepage.

Finally, it is worth mentioning the terminal box and the protection diodes, which ensure that the electric current has a unidirectional flow, like other components of a solar panel.

Although there are many components found in a solar panel, it is important to clarify that the manufacturing process is relatively simple and fast, although it is essential that it is carried out by qualified and experienced personnel in this sector.

Types of solar panels

It is now time to learn about the different types of solar panels currently in use:

Solar thermal panels

This is a very simple type of panel used to generate thermal energy by heating water.

The Thermal solar panels are composed of a transparent glass with a dark shade that allows solar radiation to pass through and also makes it possible to heat the heat transfer fluid.

In this way, heat is exchanged to the water. and then the heat transfer fluid returns to its normal temperature. Undoubtedly, this is a very common type of solar panel and it also offers a wide variety of possibilities.

Photovoltaic solar panels

Photovoltaic solar panels should be mentioned as another of the possibilities available to us.

They are those that take advantage of solar radiation to generate energy, which is obtained through cells made of silicon crystals found in this type of panels.

Among the main advantages offered by photovoltaic solar panels, it should be noted that its use is very versatile, since it is an ideal solution for homes, factories or industrial complexes.

Today, the photovoltaic solar panels have become the most in-demand option, as it is not only an environmentally friendly energy source, but also a very cost-effective and environmentally friendly one. is more economical compared to the rest of the alternatives available to us.

Are they maintained?

Solar panels require periodic maintenance, which includes, in essence, the inspection of the different components and the cleaning of the solar panels.

The main objective of the maintenance tasks is to check the condition of the different components that make up a photovoltaic panel, as well as to ensure maximum performance.

In any case, it is important to clarify that the tasks related to the maintenance of solar panels are very simple and do not present any difficulty.

It is probably for this reason that solar panels are having an increasing impact on today’s society and there is every indication that this trend will only grow in the near future.

Average price

One of the most common doubts among those who wish to install a solar panel is related to the cost of the installation.. Right?

Well, when establishing the price of a solar panel, it is necessary to consider a series of characteristics, especially if we take into account that a thermal solar panel is not the same as a photovoltaic solar panel.

As a general rule, thermal panels will have a significantly lower cost compared to photovoltaic panels, which is not surprising considering that the latter are made from silicon glass, a relatively expensive material that is difficult to obtain.

As a reference, we can establish that the price of photovoltaic solar panels ranges between 600 € and 800 € per square meterHowever, the price of other elements such as batteries, charge regulators or inverters must be added if it is an isolated installation.

On the other hand, if we talk about the price of solar thermal panels, we can highlight that the cost of the installation is about 3,000 € approximately.

In any case, in order to establish a more approximate budget, it is essential to take into account the characteristics of each installation.

In conclusion, we have made a complete review of solar panels, an ideal solution that offers a wide variety of alternatives adapted to the needs of each individual.
