How Solar Works?

Solar photo voltaic(PV) cells are made of semi-conductor materials such as silicon, which is currently the most commonly used material. When the silicon absorbs light, it releases electrons. PV cells all have one or more electric fields that force these freed electrons to flow in a certain direction. This stream of electrons is a current, and by placing metal contacts on the top and bottom of a PV cell, we can draw that current off for external applications.

When the sun is shining, the direct current (DC) electricity from the PV modules is converted to alternating current (AC) through an electronic inverter, and then fed directly into the site power distribution system where it supplies electric power. Power can be also be stored in batteries for use in the nights in the absence of sunlight.
