Solar panels for Bromley homes
If you live in Bromley, each kW of south facing solar panels will generate about 1,028 kWh a year, based on PVGIS modelling for the town. For the ten panel system most of our customers choose, that is 4,523 kWh, enough to cover a large share of a typical home's 2,500 kWh of yearly use.
Output follows the seasons. In Bromley the same 4.4kW system makes around 547 kWh in June and 161 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 Bromley
We design around your roof, not a brochure. In Bromley, moving the same ten panels from a south to an east and west roof drops yearly output to around 3,709 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 Bromley home saves about £686 a year with panels alone, or about £829 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 11.2 years with a battery, before any energy price rises or cheaper overnight battery charging.

Solar panel prices in Bromley
Government MCS data for 2025/26 puts the average cost of a 4 to 10kW system in London at £1,759 per kW. Our 4.4kW package works out at £1,476 per kW, fully installed with scaffolding and 0% VAT, and the price on your quote is fixed once we have surveyed the roof.
Planning permission in Bromley
Most homes in Bromley 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 Bromley Council; if your home is listed or in a conservation area we check with them before quoting.
Your local install team
Bromley is covered by our London team, the same engineers who work in Croydon, Sutton, London. You get a surveyor within about a week and the fitting team you meet on install day works for us, not an agency.
