Solar panels for Weymouth homes
Solar panels in Weymouth make about 1,145 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 5,038 kWh a year, a little more than the average across the 147 English towns we cover.
Output follows the seasons. In Weymouth the same 4.4kW system makes around 611 kWh in June and 171 kWh in December, and July 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 Weymouth
We design around your roof, not a brochure. In Weymouth, moving the same ten panels from a south to an east and west roof drops yearly output to around 4,131 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 Weymouth home saves about £748 a year with panels alone, or about £891 with a 5.8kWh battery that stores the afternoon surplus for the evening. On our fixed prices that is a simple payback of around 8.7 years for panels and 10.4 years with a battery, before any energy price rises or cheaper overnight battery charging.
| System in Weymouth | Makes a year | Est. saving | Fixed price | Payback |
|---|---|---|---|---|
| 4.4kW solar | 5,038 kWh | £748 | £6,495 | 8.7 years |
| 4.4kW solar + 5.8kWh battery | 5,038 kWh | £891 | £9,295 | 10.4 years |
| 6.2kW solar + 10kWh battery | 7,099 kWh | £1,138 | £12,495 | 11.0 years |
Solar panel prices in Weymouth
Government MCS data for 2025/26 puts the average cost of a 4 to 10kW system in South West at £1,631 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 Weymouth
Most homes in Weymouth 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 Dorset Council; if your home is listed or in a conservation area we check with them before quoting.
Your local install team
Weymouth is covered by our South West team, the same engineers who work in Poole, Yeovil, Bournemouth. You get a surveyor within about a week and the fitting team you meet on install day works for us, not an agency.
