We cover 255 locations across 10 regions of United Kingdom. Electricity prices in our dataset range from £0.19 to £0.28 per kWh depending on region — a spread of 47%, which is why solar savings calculators are worth materially different amounts in different parts of the country. Roof area is measured in square metres here. Every calculator below is preloaded with that location’s electricity rate and measurement units, so the payback figure reflects local conditions rather than a national average.
