How Yeovil compares
Among the places we publish figures for, Yeovil is one of 21 Somerset towns we track, and it ranks 6th of 21 for solar yield. It is a medium town in the House of Commons Library classification, with 51,778 residents, and its roofs see 2.85 peak sun hours a day across the year. That drives the standard 12 panel model to 6,621 kWh of generation, of which around 5,684 kWh is exported at 12p for £682 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Yeovil's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Yeovil sits within Somerset, its local planning authority, and the House of Commons Library classes it as a medium 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 Yeovil network
Yeovil is served by Scottish and Southern Electricity Networks (SSEN): the town's centre falls inside its Southern England licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SSEN within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Heat pumps and EV charging in Yeovil
A heat pump in Yeovil
Solar and a heat pump pull in opposite directions through the year: Yeovil'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.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Yeovil
A 12-panel roof in Yeovil makes about 810 kWh in May. 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Solar in Yeovil: your questions answered
What could a roof in Yeovil generate?
PVGIS puts a roof in Yeovil at 1,041 kWh per kWp a year, 2.85 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,620 kWh a year, most of it between April and September.
How much are solar panels in Yeovil?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Yeovil before a battery. What Yeovil changes is the return, about 6,620 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Yeovil?
Usually not in advance. SSEN, the network operator for Yeovil, 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 can I earn from exporting solar in Yeovil?
With typical use and no battery, a 12-panel system in Yeovil exports about 5,684 kWh a year. At 12p per kWh that is roughly £682; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Yeovil?
Yes, at a lower level. PVGIS gives Yeovil 35.7 kWh per kWp in December and 39.7 in January, so a 12-panel system makes about 230 kWh and 250 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Yeovil compares with its neighbours
How the towns nearest Yeovil compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Yeovil |
|---|---|---|
| Yeovil | 1,041 | this town |
| Sherborne | 1,043 | +2 kWh |
| Street | 1,032 | −9 kWh |
| Glastonbury | 1,033 | −8 kWh |
| Chard | 1,050 | +9 kWh |
| Bridport | 1,105 | +64 kWh |
| Gillingham (Dorset) | 1,035 | −6 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
