Solar & battery installation in Stevenage
Britain's first new town has some of the most solar-ready housing in Hertfordshire — consistent post-war roofs, sensible pitches, minimal shading. Across SG1–SG2 we deliver custom design, MCS installation, the DNO application and every certificate.
We work right across Stevenage — from the Old Town High Street, Fairlands Valley Park and Knebworth's borders to the surrounding Hertfordshire neighbourhoods.

The company is TrustMark, NAPIT and RECC registered, a company owner attends every installation, and the full job — design, install, DNO grid application and certification — is handled in-house.
How much does solar panel installation cost in Stevenage?
Recent real ECONEXIS installs start from £4,990 for a solar-only system, or £6,690 for a 10-panel system with a 5 kWh battery — up to around £14,000 for a 20-panel system with a large battery. As a guide to sizing: The new-town terraces take standard mounting fast, and the Great Ashby and Poplars developments offer large modern roof planes for bigger arrays with high-capacity batteries, which shapes how many panels fit. Your fixed Stevenage quote is confirmed after a free custom design — usually within 24 hours.
Do you actually cover Stevenage and the SG1–SG2 postcodes?

Your free custom design usually comes back within 24 hours. After your survey and go-ahead, most Stevenage installations are booked within a few weeks and completed in one to two days on site.

In short: Permitted development covers almost every Stevenage install; the Old Town's High Street conservation area is the one place we double-check. We check the rules for your exact address during the free design and handle any paperwork needed — you won't have to deal with the council yourself.
Who handles the DNO application for my Stevenage install?
We do, completely. We prepare and submit the DNO application for your Stevenage property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
