Solar in this area

What solar could generate in this area.

We looked at the metered output of 14,879 real UK solar installations to see how much a roof could make. In the area this installer covers, we estimate the following:

≈933 kWh per kWp a year

For SA11 that is about the UK average: a 4 kWp system, about ten panels, would make roughly 3,700 kWh a year on a well-placed roof. Across the Swansea (SA) postcode area, the middle half of 302 metered systems made 695–841 kWh per kWp in 2024.

Check your roof's potential today with our roof check. This is an estimate: the size and suitability of your roof, the way it faces and other factors all play into what you could generate, so an in-person roof survey is always recommended.
