Frequently asked questions

How much can offices 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 ~4–9 years.

How many office roofs does Sunseam track in England & Wales?

Sunseam ranks 33,152 office-type commercial roofs, a combined rooftop-solar potential of about 6,644.9 MWp.
