Work out what your roof could deliver
This calculator uses the area's real solar production, between 1,350 and 1,500 kilowatt hours a year per installed kilowatt according to PVGIS, the European Commission's reference tool. No sign-up and no details left behind: the numbers are worked out in your browser.
The result is a serious estimate, not a study: the real study is done with your roof and your consumption in front of us. If the numbers add up for you, that is the next step.

Three questions and we give you an honest range, with every assumption in plain sight. No phone number or email needed to see the result.
If it is not on the list, type it anyway. Across this area, sunshine per kWp barely changes from one town to the next.
