Against Great Britain as a whole: Sherborne makes 1,043 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Sherborne is 13% above it.
How Sherborne compares
Small towns rarely get published solar figures, so here are the numbers for Sherborne. It is one of 15 Dorset towns we track, and it ranks 13th of 15 for solar yield, a town of 10,933 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,043 kWh per kWp a year, 2.86 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £931 of year one benefit, £247 of it from your own generation and £684 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Sherborne's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Sherborne sits within Dorset, its local planning authority, and the House of Commons Library classes it as a small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Connecting solar to the Sherborne network
On NESO's licence-area map, Sherborne is in Southern England, which Scottish and Southern Electricity Networks (SSEN) operates. That makes SSEN the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Adding a heat pump or an EV charger in Sherborne
A heat pump in Sherborne
Solar and a heat pump pull in opposite directions through the year: Sherborne's roofs make 1,130 kWh from November to February on a 12-panel system, and 3,130 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Sherborne
A 12-panel roof in Sherborne makes about 810 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Sherborne
What could a roof in Sherborne generate?
PVGIS puts a roof in Sherborne at 1,043 kWh per kWp a year, 2.86 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,630 kWh a year, most of it between April and September.
What would 12 solar panels cost in Sherborne?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Sherborne differs is output: about 6,630 kWh a year from that system.
Do I need permission from the DNO for solar in Sherborne?
Usually not in advance. SSEN, the network operator for Sherborne, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW. "See our DNO explainer.
How much would export pay on a system in Sherborne?
It is exported. With typical use and no battery, about 5,697 kWh of the 6,630 kWh a 12-panel system makes in Sherborne goes to the grid, around £684 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Sherborne?
Yes, at a lower level. PVGIS gives Sherborne 36.4 kWh per kWp in December and 39.6 in January, so a 12-panel system makes about 230 kWh and 250 kWh in those months, against 810 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Sherborne compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Sherborne.
| Town | kWh per kWp a year | vs Sherborne |
|---|---|---|
| Sherborne | 1,043 | this town |
| Yeovil | 1,041 | −2 kWh |
| Gillingham (Dorset) | 1,035 | −8 kWh |
| Shaftesbury | 1,036 | −7 kWh |
| Street | 1,032 | −11 kWh |
| Glastonbury | 1,033 | −10 kWh |
| Shepton Mallet | 1,015 | −28 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.

An east west split gives up about a fifth of the annual total, and can still be worth more than south.
