Solar panels for Stevenage homes
Solar panels in Stevenage make about 1,019 kWh for every kW fitted on a south facing roof, according to the EU's PVGIS model for the town's exact position. That means a typical 4.4kW system of ten panels produces around 4,484 kWh a year, a little more than the average across the 147 English towns we cover.
Output follows the seasons. In Stevenage the same 4.4kW system makes around 538 kWh in June and 158 kWh in December, and July is usually the strongest month. About 68% of the year's power arrives between April and September, which is why a battery matters more here in summer evenings than in the depths of winter.
Which roofs work best in Stevenage
We design around your roof, not a brochure. In Stevenage, moving the same ten panels from a south to an east and west roof drops yearly output to around 3,677 kWh. That is still well worth doing, and the morning and evening split often suits a household that is out during the day.
What you could save
At the current price cap of 26.32p per kWh and 12p for exported power, we estimate a Stevenage home saves about £681 a year with panels alone, or about £824 with a 5.8kWh battery that stores the afternoon surplus for the evening. On our fixed prices that is a simple payback of around 9.5 years for panels and 11.3 years with a battery, before any energy price rises or cheaper overnight battery charging.

Planning permission in Stevenage
Most homes in Stevenage do not need planning permission for roof panels. Under permitted development rules they can be fitted as long as they sit no more than 200mm proud of the roof and stay below the ridge. The exceptions are listed buildings and, in conservation areas, walls facing a road. The local planning authority is Stevenage Council; if your home is listed or in a conservation area we check with them before quoting.
Your local install team
Stevenage is covered by our East of England team, the same engineers who work in Luton, St Albans, Hemel Hempstead. You get a surveyor within about a week and the fitting team you meet on install day works for us, not an agency.
