The use of solar energy is an increasingly popular alternative method of producing electrical energy.  Not only are resources infinite but the process of producing electricity is clean meaning that no contaminated gases are released into the atmosphere causing a deterioration of quality.  Furthermore, solar energy can be used in any part of the world that receives sufficient sunlight, in fact, the majority of countries all over the world.  Their increasing popularity is not only due to these advantages of producing clean energy but also due to its versatility, affordable price and sense of social responsibility that it bestows upon the purchaser. 
Solar cells are used to produce electricity through the direct transformation of solar radiation by means of the photovoltaic effect, therefore are the basis of any installation using solar energy to produce electricity.
