Undoubtedly one of the most important activities in developed countries for reducing the consumption of impure energies is to develop technologies which accomplish renewable and unlimited energy sources. This affair will influence both economic and environment a lot. In other words by using renewable source of energy, termination of fossil fuel source and their harms to the environment will be prohibited. Until the renewable source of energy is being used, the photovoltaic systems will be one of the best ways to get energy from solar system. Actually this phenomenon is based on the theory that describes radiation energy as a particle. Photovoltaic system generates electric power by using solar cells to convert energy from the sun into DC electricity. By using the achieved electricity power and electrical and electronic equipments it is possible to provide electrical energy related to all loads of AC and DC.
