Is My Roof Suitable for Solar Panels?
Eco Solar Panels UK made this check for the first question most people have about solar. Answer up to seven questions, one at a time, and it tells you whether panels are likely to pay on your roof and what to look into next.
How it works
What the check looks at
The check follows the order a surveyor would. First the things that can stop a job outright: a listed building, which needs planning permission, and a roof that needs replacing soon. Then the things that decide how much the panels make: direction and shade. Generation figures come from PVGIS v5.2 for Derby: about 979 kWh a year per kWp facing south and 773 kWh facing east or west.
It can't see your roof, so treat the result as a starting point. The solar panel calculator shows what a system would cost and save, and the planning guide covers conservation areas and listed homes.
