HOW DO SOLAR PANELS WORK?

Solar electricity systems capture the sun’s energy using photovoltaic cells. The cells don’t need direct sunlight to work – they can still generate electricity on a cloudy day – but generate more electricity in stronger sunshine. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.

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.

IS MY PROPERTY SUITABLE?

Solar panels are lightweight and highly adaptable. Ideally, you need a south, south-east or south west facing roof space that isn’t shaded. Even the smallest space can generate a worthwhile amount of electricity but we wouldn’t recommend installing panels on north-facing roofs.

DO I NEED PLANNING PERMISSION?

Generally, installations fall under permitted development rights so planning permission is not required but always check first.

HOW RELIABLE IS THE TECHNOLOGY?

Solar panels are robust and carry warranties of 5-10 years, depending on the manufacturer. They are also guaranteed to perform at no less than 80 per cent of their original performance outputs up for up to 25 years.

HOW EXPENSIVE ARE THEY TO MAINTAIN?

Solar PV panels have no moving parts and need little maintenance – you’ll just need to keep the panels relatively clean and make sure trees don’t begin to overshadow them. Panels are mounted at an angle and in most cases, rain water is sufficient to keep them clean and ensure optimal performance.
