Solar panels for Kingston upon Thames homes
If you live in Kingston upon Thames, each kW of south facing solar panels will generate about 1,024 kWh a year, based on PVGIS modelling for the town. For the ten panel system most of our customers choose, that is 4,506 kWh, enough to cover a large share of a typical home's 2,500 kWh of yearly use.
Output follows the seasons. In Kingston upon Thames the same 4.4kW system makes around 547 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 Kingston upon Thames
Roof direction changes the numbers more than the town does. An east and west split roof in Kingston upon Thames would make about 3,695 kWh from the same ten panels, roughly 18% less than south, but it spreads generation across the morning and evening when most families are home. North facing roofs are rarely worth covering at normal pitches.
What you could save
At the current price cap of 26.32p per kWh and 12p for exported power, we estimate a Kingston upon Thames home saves about £684 a year with panels alone, or about £827 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.

Planning permission in Kingston upon Thames
Most homes in Kingston upon Thames 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 Kingston upon Thames Council; if your home is listed or in a conservation area we check with them before quoting.
