Solar panel electricity systems, also known as solar photovoltaics (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.
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.
- If your system is producing more electricity than you need, you can sell the surplus.
- Cut your carbon footprint. Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save nearly two tonnes of carbon per year.
