Photovoltaic solar energy directly transforms sunlight into electricity using a technology based on the photovoltaic effect. When the sun’s radiation falls on one of the faces of a photoelectric cell (which make up the panels), a difference in electrical potential is produced between both faces that causes the electrons to jump from one place to another, thus generating electric current.

There are three types of solar panels: photovoltaic, power generators for the needs of our homes; thermal, which are installed in houses with direct sunlight; and thermodynamic, which work despite the weather variation, that is, even at night, rainy or cloudy.

Although the photovoltaic effect was known since the 19th century in the early stages of photovoltaic technology, this type of energy was used to power satellites. It was in the 1950s, in the midst of the space race, when photovoltaic panels accelerated their development until they now became an alternative to the use of fossil fuels.

As benefits of these electric generators , it should be noted that the electrical energy generated by photovoltaic solar panels is inexhaustible and does not pollute, which is why it contributes to sustainable development and also they provide heavy power solutions, in addition to favoring the development of local employment. Likewise, it can be used in two different ways: it can be sold to the electricity grid or it can be consumed in isolated places where there is no conventional electricity grid. For this reason, it is a particularly suitable system for rural or isolated areas where the power line does not reach or its installation is difficult or expensive, or for geographical areas whose climate allows many hours of sunshine per year.
