Solar panels capture the sun’s energy using photovoltaic (PV) cells. They don’t need direct sunlight to work (thankfully for us in the UK). Ideally you’ll have a roof that faces south (more or less) and isn’t shaded.
The PV cells convert sunlight into electricity, which you can use for your household appliances and lighting. You can also heat your hot water with the sun’s energy using solar thermal systems.
So what are the benefits? Solar energy is 100% renewable and doesn’t release any carbon dioxide or greenhouse gases.
Solar energy can also save you money. Sunlight is free, so your energy bills will be reduced.
What size of system do you need? You should first think about how much energy you use in your home, and how much of it you want to generate with renewables.
You can use our solar panel calculator to work out what size solar panel system is right for you.
