How Thetford compares
Among the places we publish figures for, Thetford is one of 16 Norfolk towns we track, and it ranks 14th of 16 for solar yield. It is a medium town in the House of Commons Library classification, with 25,524 residents, and its roofs see 2.81 peak sun hours a day across the year. That drives the standard 12 panel model to 6,519 kWh of generation, of which around 5,582 kWh is exported at 12p for £670 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Thetford's own yield.
Thetford sits within Breckland, 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 Thetford network
Thetford is served by UK Power Networks: the town's centre falls inside its East 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 UK Power Networks 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. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Beyond the panels: heating and car charging in Thetford
A heat pump in Thetford
Solar and a heat pump pull in opposite directions through the year: Thetford's roofs make 1,110 kWh from November to February on a 12-panel system, and 3,070 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 Thetford
From April to September, 68% of a Thetford roof's yearly output arrives, peaking at about 790 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Thetford
What could a roof in Thetford generate?
PVGIS puts a roof in Thetford at 1,025 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,520 kWh a year, most of it between April and September.
What would 12 solar panels cost in Thetford?
£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 Thetford differs is output: about 6,520 kWh a year from that system.
Do I need permission from the DNO for solar in Thetford?
Usually not in advance. UK Power Networks, the network operator for Thetford, 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. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. "See our DNO explainer.
How much would export pay on a system in Thetford?
It is exported. With typical use and no battery, about 5,582 kWh of the 6,520 kWh a 12-panel system makes in Thetford goes to the grid, around £670 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 Thetford?
Yes, at a lower level. PVGIS gives Thetford 36.6 kWh per kWp in December and 38.4 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 790 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Thetford compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Thetford |
|---|---|---|
| Thetford | 1,025 | this town |
| Brandon (West Suffolk) | 1,003 | −22 kWh |
| Watton | 1,017 | −8 kWh |
| Mildenhall | 1,033 | +8 kWh |
| Bury St Edmunds | 1,042 | +17 kWh |
| Attleborough | 1,036 | +11 kWh |
| Diss | 1,045 | +20 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.

Solar panel grants and funding in 2026: what actually exists, and what is a sales pitch
No blanket grant exists, and the four supports that do exist are better than most of the adverts.

No panels means one job: buy cheap, use later. The tariff decides whether it pays.
