Against Great Britain as a whole: Watton makes 1,017 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Watton is 10% above it.
How Watton compares
Small towns rarely get published solar figures, so here are the numbers for Watton. It is one of 16 Norfolk towns we track, and it ranks 15th of 16 for solar yield, a town of 11,961 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,017 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £911 of year one benefit, £247 of it from your own generation and £664 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Watton'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.
Any planning application in Watton sits with Breckland, and its official House of Commons Library settlement class is 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.

The network operator for Watton
UK Power Networks owns and runs the local electricity network in Watton, as part of its East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
Larger systems go through G99 instead, applied for before installation. On timing: 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.

Heat pumps and EV charging in Watton
A heat pump in Watton
Heating demand peaks when solar is weakest. In Watton, a 12-panel system makes about 230 kWh in December and 240 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Watton
Summer is where a car earns its place. In July, 12 panels in Watton make about 790 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Solar in Watton: your questions answered
How much electricity do solar panels make in Watton?
About 6,470 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Watton: 1,017 kWh per kWp, or 2.79 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
What does a typical solar system cost in Watton?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Watton, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,470 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Watton, and what does it need from me?
UK Power Networks covers Watton. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What happens to the solar I do not use in Watton?
Around £664 a year at 12p per kWh, for the roughly 5,531 kWh a 12-panel system in Watton exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Watton get in December?
December is the low point: about 230 kWh from a 12-panel system in Watton, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,090 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Watton 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 Watton |
|---|---|---|
| Watton | 1,017 | this town |
| Swaffham | 1,016 | −1 kWh |
| Attleborough | 1,036 | +19 kWh |
| Dereham | 1,028 | +11 kWh |
| Thetford | 1,025 | +8 kWh |
| Wymondham | 1,036 | +19 kWh |
| Brandon (West Suffolk) | 1,003 | −14 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.
