# Is My Roof Suitable for Solar Panels?

[Eco Solar Panels UK](https://ecosolarpanelsderby.co.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](https://re.jrc.ec.europa.eu/pvg_tools/en/) 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](https://ecosolarpanelsderby.co.uk/tools/solar-panel-calculator/) shows what a system would cost and save, and [the planning guide](https://ecosolarpanelsderby.co.uk/guide/solar-panels-planning-permission-derby/) covers conservation areas and listed homes.
