What is solar photovoltaic (PV)?
Solar photovoltaic cells involve some of the most exciting new technology available. These cells take the suns direct rays, the most readily available renewable source, and turn them into energy. When a photon of light hits the silicon on your solar panel, electrical energy is released in the form of an electron. These electrons are then manipulated to result in an electrical charge. Its a much more efficient process than solar thermal energy, because converting heat energy to electricity is quite complex.
