Solar panels for Lowestoft homes
A 4.4kW solar system in Lowestoft should produce roughly 4,646 kWh a year. That figure comes from PVGIS, the European Commission's solar model, run for Lowestoft itself rather than a national average, at 1,056 kWh per kW of panels on a south facing 35 degree roof.
Output follows the seasons. In Lowestoft the same 4.4kW system makes around 570 kWh in June and 151 kWh in December, and May is usually the strongest month. About 69% 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 Lowestoft
Roof direction changes the numbers more than the town does. An east and west split roof in Lowestoft would make about 3,810 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 Lowestoft home saves about £701 a year with panels alone, or about £844 with a 5.8kWh battery that stores the afternoon surplus for the evening. On our fixed prices that is a simple payback of around 9.3 years for panels and 11.0 years with a battery, before any energy price rises or cheaper overnight battery charging.

Planning permission in Lowestoft
Most homes in Lowestoft 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 East Suffolk Council; if your home is listed or in a conservation area we check with them before quoting.
