Against Great Britain as a whole: Wantage makes 1,031 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Wantage is 11% above it.
How Wantage compares
Small towns rarely get published solar figures, so here are the numbers for Wantage. It is one of 20 Berkshire towns we track, and it ranks 4th of 20 for solar yield, a town of 14,568 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,031 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £921 of year one benefit, £247 of it from your own generation and £674 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Wantage'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 Wantage sits with Vale of White Horse, 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 Wantage
The distribution network operator (DNO) for Wantage is Scottish and Southern Electricity Networks (SSEN), which runs the Southern 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 SSEN is notified within 28 days of switch-on rather than asked beforehand.
Above that, G99 means applying before the work is booked. 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 Wantage
A heat pump in Wantage
Heating demand peaks when solar is weakest. In Wantage, a 12-panel system makes about 240 kWh in December and 260 kWh in January, a fraction of its 800 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Wantage
Wantage's July output, about 800 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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 Wantage: your questions answered
How much electricity do solar panels make in Wantage?
About 6,560 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Wantage: 1,031 kWh per kWp, or 2.82 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
Is solar more expensive in Wantage?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Wantage, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,560 kWh a year here, which is what drives payback.
Which DNO covers Wantage, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Wantage. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Wantage?
On the 12p export scenario, a 12-panel system in Wantage sends about 5,620 kWh a year to the grid, worth around £674. The export rates table compares what each supplier pays.
How much solar does Wantage get in December?
December is the low point: about 240 kWh from a 12-panel system in Wantage, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,120 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Wantage 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 Wantage |
|---|---|---|
| Wantage | 1,031 | this town |
| Grove | 1,034 | +3 kWh |
| Didcot | 1,040 | +9 kWh |
| Faringdon | 1,030 | −1 kWh |
| Abingdon-on-Thames | 1,027 | −4 kWh |
| Wallingford | 1,017 | −14 kWh |
| Highworth | 1,018 | −13 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.
