Energy plays a vital role for the development of society and its demand is continuously increasing. Conventional sources of energy which are being used impose adverse effect on the environment. So renewable energy resources based on biomass energy, water energy, nuclear energy, geothermal energy, tidal energy, wind energy, solar energy etc are best alternatives. Among these, solar energy is available abundantly around us. The PV system converts sunlight into electrical power whenever light falls on PV cell.
