Frequently asked questions
How much can retails save with solar?
It scales with roof size and how much electricity is used on-site by day. Large units commonly see a total benefit of low tens of thousands to six figures a year, split between the avoided electricity bill (capped at the building's own bill) and export income on the surplus, with payback ~4–5 years.
How many retail roofs does Sunseam track in England & Wales?
Sunseam ranks 23,015 retail-type commercial roofs, a combined rooftop-solar potential of about 6,934.2 MWp.
