Learn what are solar panels and how do they work is something fundamental if we really want to take advantage of what solar energy offers and move on to electrical self-consumption. Solar energy is one of the renewable energies that we can best take advantage of if we propose it and that, really, offers us many possibilities, being able to be independent in terms of electricity supply, have a self-sufficient house or premises and, incidentally, preventing pollution from increasing by leaps and bounds as before.
Do you want to sign up for electricity self-consumption and learn what solar panels are, how they work, where to buy them and much more? So, you have reached the place you were looking for, because in this Green Ecologist article we talk about all of it.
The solar energy is the one that comes from the sun's rays that reach us to the surface of the Earth. The Sun is a star and emits energy in the form of electromagnetic radiationTherefore, thanks to the distance at which we are, light and heat reach the planet.
The Sun is an energy source considered one of the inexhaustible natural resources, as well as renewable energy resources, which makes solar energy a sustainable and alternative energy. It is a type of energy with which the negative environmental impact is significantly reduced, buying it with dirty and highly polluting energies such as fossil fuels.
There are areas of the planet that can benefit from this type of energy more easily than others. For example, Spain is one of the sunniest areas there is and is one of the areas in which the highest rate of solar radiation is collected in Europe that is usable as energy, converting it into electricity and other possibilities. Specifically, the latest studies have estimated that Spain receives about 1,500 kilowatt hours throughout the year per square meter. Until recently, other countries have been at the fore with this technology and this country has been at the tail of the solar energy producers even having this amount of solar rays, but lately the outlook has improved, the prices of solar panels to obtain this energy have dropped and there are more facilities to buy, install and use them and take advantage of the electrical self-consumption. In fact, in the last year its growth in Spain has been spectacular and an important advance towards renewable energies is expected to obtain electricity and more benefits.
In the video below you can learn more about solar energy.
The photovoltaic effect is the partial transformation of the energy that comes from the light or light energy that is in electrical energy. To get this electricity from the Photovoltaic Solar Energy photovoltaic or solar cells are used.
Learn more about what solar energy is and what it is for in this other Green Ecologist article.
The solar panels are the structures that allow us capture the sun's energy to transform it into electricity and for a variety of uses. These solar panels are normally made of aluminum and are made up of a set of several cells or solar cells, which mainly contain silicon. Thanks to the photovoltaic effect, explained above, these solar panel cells are capable of capturing solar radiation and transforming it into electrical energy.
During this process, what happens is that the photovoltaic effect occurs when the radiation from the Sun falls on the surface of the solar cell or cell, more specifically on the different electrons of the atoms of the solar cell, and in this way each Electron can be released from its position in the different atoms and go on to create a current of electrons or electricity that goes through the electrical circuit, thus obtaining the new energy or usable electric current. So it is How do solar panels workWell, one is made up of a certain amount of solar cells and these, in turn, of a large number of atoms with electrons that capture and transmit this energy; so that the whole that is the panel can absorb and produce a large amount of energy.
Few solar panels are usually installed in a home, even just one, as it is normally enough for self-consumption and to have a sustainable, ecological and self-sufficient house. However, not only the electrical self-consumption at home is expanding, but also companies that seek it for their own consumption and those that have solar farms, orchards or solar gardens or solar fields for the production of electricity with a more sustainable process than those used up to now and its distribution to companies and individuals. In the latter case, it is about large areas full of large solar panels, something similar to wind farms.
There are three types of panels or solar panels:
In addition, within these there are more types of different solar panels according to other factors. Within the photovoltaic solar panels, which are those that capture light energy to transform it into electricity, we find monocrystalline panels (silicon), polycrystalline panels (silicon) and other types that are not composed of silicon. On the other hand, between thermal solar panels, which are the ones that capture the sun's energy to transform it into thermal or heat energy, there are low-temperature collectors, medium-temperature collectors and high-temperature collectors. Finally, the hybrid solar panels They are those that combine both types of plates in one to be able to produce both electricity and strain at the same time.
There are many advantages offered by solar panels and electricity self-consumption and, therefore, more and more people are joining the use of renewable, sustainable and clean energy for their home. As advantages we highlight:
However, like everything in life, we can also see the side of the disadvantages of solar panels:
According to the installation of solar panels on the roof of a house, a business or a companyWe want to indicate that a series of basic factors must be taken into account to ensure that it will work well and that the area chosen to place them is the most appropriate.
At Ecologist Verde we recommend that you go to professional technicians of the installation of solar panels or panels to ensure good results and guarantees. For this reason, we offer you information on where to buy solar panels and on companies that install these products. We recommend you consult:
