Solar panels, an inverter and a generation meter make up a solar PV system. These three main components together, will create electrical energy. As the electricity made by solar panels is totally FREE, try to use as much as you can to reduce energy bills. You will soon learn how to get the most out of your panels by watching your electricity meter when using things like washing machines and kettles during the day The solar panels will be fitted to your roof or a ground mount to create free electricity from sunlight. The electricity generated is fed through an inverter (usually installed in your loft) which coverts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can then be fed into a commercial electrical grid or used by a local off grid electrical networ
