Solar panels – also known as photovoltaic (PV) panels – are made from silicon, a semiconductor material. Such a material has some electrons which are only weakly bound to their atoms. When light falls on the surface of the silicon, electrons break free and can become part of an electric current. . Solar panels have become much cheaper in recent years. They have also become much more efficient – they produce more electrical power from the. .
