How does solar PV work?

           Solar PV systems convert light into electrical power using a thin layer of semi-conducting material, usually silicon, encased between a sheet of glass and a polymer resin. They range in size from a few square centimetres,for example on calculators and watches to systems of hundreds of square metres made from interconnected modules that form an array. When exposed to daylight electrons in the semi-conducting material become energised. These electrons are then able to flow through the material generating a direct current (DC). The DC is carried through wiring to an inverter which converts the current to 240V alternating current (AC)so it can be connected to your home’s main electricity supply.
