How does solar work?
At its simplest, solar panels (also known as solar photovoltaics, or PV) convert sunlight into electricity.
Uswitch tip: You don't need scorching heat or direct sun for this to work. Modern panels are incredibly efficient at capturing diffused light, meaning they still generate power on typically overcast British days.
Capturing sunlight
Solar panels are made of cells containing semi-conducting materials. When light hits these cells, it creates an electrical field.
Conversion
The panels produce Direct Current (DC) electricity. Since your home runs on Alternating Current (AC), the power is sent to a small box called an inverter to be converted.
Powering your home
This electricity flows into your consumer unit (fuse box) to power your lights, appliances, and gadgets.
The grid connection
If you generate more power than you need, the excess flows back into the National Grid. If you need more than you’re generating (like at night), you simply pull electricity from the grid as normal.
