The Photovoltaic systems are devices which provide solar energy by using photovoltaic effect. It is also known as PV system or Solar power system. The PV system is made of a solar panel which absorbs the sunlight and converts it to energy, a solar inverter to change the DC current into AC current, mounting, cabling and other electrical components. It may be small, roof-top mounted, building integrated systems depending on their purpose and most of the systems are Grid connected. The performance of a PV system can be improved by integrating a solar tracking system with it. Since the use of Photovoltaic cells is increasing rapidly, the prices have reduced drastically. It is one the environmental friendly source of energy.
