Understand UK solar before you speak to a salesperson.
Estimate the numbers, compare quotes and learn what changes by region—without handing your details to five companies first.
What could solar look like for your home?
Change every assumption. This is a planning estimate, not an installer quote or funding decision.
Regional generation factors are deliberately conservative planning assumptions. Your roof, shading, panel layout and local weather can change the result. The import benchmark is the Ofgem Great Britain average for 1 July–30 September 2026; Northern Ireland tariffs differ.
Model the economics
Adjust system cost, electricity price, export tariff and household demand instead of accepting one sales figure.
Check the quote
Compare system size, equipment, warranties, scaffolding, network paperwork and realistic generation.
Choose your next step
Keep researching, ask for a manual quote review, or opt in to a suitable installer introduction.
One calculator, regional context
Solar output, support schemes, export arrangements and installer checks are not identical everywhere. Start with the region that applies to your property.
