A solar panel, also know as a PV panel or module, is a device that collect sunlight and converts it into electric current. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect. " Because most appliances don't use DC electricity, devices called inverters then convert it to. At the heart are photovoltaic (PV) cells that convert sunlight into electricity, supported by protective and structural layers that ensure it's delivered safely and reliably. Most panels include solar cells, tempered glass, encapsulant, a backsheet, a metal frame, an inverter, and a junction box. It does not matter whether you are interested in solar for your house or business, or just want to know how clean energy works; understanding the.
