Frequently asked questions
How many commercial roofs suit solar in Cornwall?
Sunseam ranks 920 large commercial roofs in Cornwall, with a combined rooftop-solar potential of about 166.6 MWp.
Which buildings in Cornwall face MEES pressure?
Around 291 of the ranked buildings in Cornwall sit at EPC Band D–G. The minimum to let is Band E today; the government's long-term MEES target is EPC B for large non-domestic buildings (over 1,000 m²), expected around 2031, so the biggest, lowest-rated roofs have the clearest future-proofing reason to act.
