Simply put, Solar Power systems are like any other electrical power generating systems just the equipment used is different than that used for conventional electromechanical generating systems. However, the principles of operation and interfacing with other electrical systems remain the same, and are guided by a well-established body of electrical codes and standards. Primary component of a Solar Power system is PV panels. Although a PV array produces power when exposed to sunlight, a number of other components are required to properly conduct, control, convert, distribute, and store the energy produced by the array.

Depending on the functional and operational requirements of the system, the specific components required, and may include major components such as battery bank, system & battery charge controller, auxiliary energy sources, a DC-AC power inverter. Figure below show a basic diagram of a photovoltaic system and the relationship of individual components.
