Solar Photovoltaic (PV) Systems convert light from the sun into electricity. Solar cells produce direct current (DC) electricity from light, which can be used to power DC equipment or to recharge a battery.
The basic photovoltaic cell produces only a small amount of power. Cells can be interconnected to form modules, which can, in turn, be connected to arrays to create yet more energy. Because of this modularity, photovoltaic systems can be designed to meet any electrical requirement, no matter how large or how small.
