How Do Solar Panels Work?

Solar panel electricity systems, also known as solar photovoltaic (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work—they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground. The benefits of solar electricity.
