Your roof,
earning its keep.
See how many panels your roof actually fits, how much you’d generate over a year, and whether a battery pays for itself — all read straight from satellite.

What we check
Real roof numbers, not a postcode guess.
We use the same imagery + irradiance models Google uses to size commercial solar projects — applied to your specific roof, your pitch, your shading.
Roof pitch, shading + orientation
South-facing vs east-west, chimney shading, tree losses — read from your actual roof, not the postcode average.
Real annual kWh
PVGIS modelling against your roof's azimuth and pitch — a number we'd defend to an MCS installer, not a marketing one.
Battery payback that pays back
We model your evening usage against generation — so you only buy the kWh of battery that actually earns its money.
What you'd actually save
Against your real tariff (or our UK-average if you don't have one). Self-consumption + export — separated, so the maths is honest.
How it works
Five minutes, your address is enough.
Your address
That's it. We pull your roof from satellite, your tariff from your latest bill (optional), and your usage pattern from a couple of quick questions.
We do the modelling
Google Solar buildingInsights + PVGIS yield + your tariff. All cross-checked against UK install norms.
A clear, quote-ready report
kWp, annual kWh, battery size, payback. Shareable straight with any MCS installer for a real quote.
