Commercial solar for warehouses & distribution
Large, low-rise warehouse and distribution roofs are the strongest commercial-solar targets, big roofs, big daytime electricity bills.
Estimated £1,299,459,457 in combined potential annual savings across these roofs.
Frequently asked questions
How much can storages 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 ~6–9 years (faster the more electricity is used on-site by day).
How many storage roofs does Sunseam track in England & Wales?
Sunseam ranks 23,565 storage-type commercial roofs, a combined rooftop-solar potential of about 10,824.9 MWp.
Figures are estimates modelled using standard assumptions, indicative, not quotes.
Our capacity estimates are under revision. Where several adjoining units share one mapped roof outline, or where no outline could be matched and we size from floor area instead, an individual estimate can be too high or too low. We are rebuilding how roof size is measured and will restate the affected figures once that work is complete. Roof counts, energy ratings and ownership figures are unaffected.
