Photovoltaic solar panels are more commonly known as "solar panels" and are generally installed at roof level. Their main objective is to capture solar radiation to transform it into direct current electricity. This can even be converted into a 220V alternating current for use in buildings and a process of resale to an energy supplier. The best photovoltaic solar panels can be monocrystalline or polycrystalline. They are differentiated by the characteristics of the cells that form the photovoltaic surface. In the first case, the panel consists of a single block of molten silicon. On the other hand, polycrystalline panels are manufactured by assembling several cells.
