How Solar PV (electric) Panels work

Advice
Solar Panels

How does solar PV work?

Solar Photovolteic (PV) systems – are a collection of solar panels that turn sunlight into electricity through the ‘solar cells’ they contain. These cells are made from thin layers of a ‘semiconductor’ material (traditionally silicon) between layers of glass.

Electricity leaves the panel as direct current (DC) and passes through an inverter that converts it to 240V alternating current (AC) that can be used in your home. When your solar panels are generating, the electricity will be used in any appliances that are switched on at the time, like the washing machine or TV.

Export – you may not use all of the electricity that the solar panels generate.  This excess electricity is sent back to the grid to be used elsewhere.  The energy firms can pay for this exported electricity and Cynon Taf will receive payment for the electricity exported. These will be used to maintain the solar panel and invest in the housing stock. It is important you use as much electricity from the solar panels as possible as this will have the biggest difference financially
