Its production is based on the physical phenomenon known as "photovoltaic effect", which basically consists on changing sunlight into electric energy by means of some semi-conductor devices called photovoltaic cells.

    These cells are made of pure silicon (one of the elements that abound and main component of sand) with the addition of impurities of certain chemical elements (boron and phosphorus) and are capable of generating a power of 2 to 4 Amperes, with a voltage of 0,46 to 0,48 Volts by using luminous radiation as its source.

    The cells are assembled by series on solar or modular panels in order to get a suitable voltage. Part of the radiation that comes into contact is lost by reflection (it bounces) and the other part by transmission (goes through the cell). The rest is able to send electrons from one coat to the other creating thus a power proportional to the radiation that comes into contact. The glareshield coat enhances the efficacy of the cell.
