PV SOLAR PANELS
The benefits of solar electricity
- Cut your electricity bills.Sunlight is free, so once you’ve paid for the initial installation, your electricity costs will be reduced.
- Get paid for the electricity you generate.The UK government’s Feed-in Tariff scheme pays you for the electricity you generate, even if you use it.
- Sell electricity back to the grid.If your system is producing more electricity than you need, you can sell the surplus back to the grid through the Feed-in Tariff scheme.
- Cut your carbon footprint. Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical system including solar panels for home use could save nearly two tonnes of carbon per year.
How do Solar Panel (PV) Cells Work?
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 power of a PV cell is measured in kilowatts peak (kWp). That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof.
