Photovoltaic (PV) devices generate electricity directly from sunlight using a process that naturally occurs in some materials. Within a certain class of crystals, electrons are freed when tiny packets of light from the sun — called photons — are absorbed. These electrons that are freed travel through a circuit as electricity.
Solar PV systems are groupings or “Arrays” of modules wired together along with an inverter and utility meter to produce electrical power.
Solar PV systems can be part of a total approach to reduce greenhouse gas emissions, protect our environment and reduce our dependence on foreign oil.
