Against Great Britain as a whole: Wallingford makes 1,017 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Wallingford is 10% above it.
How Wallingford compares
Small towns rarely get published solar figures, so here are the numbers for Wallingford. It is one of 20 Berkshire towns we track, and it ranks joint 15th of 20 for solar yield, a town of 8,735 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 Wallingford'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 Wallingford sits with South Oxfordshire, 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.

SSEN and your Wallingford connection
Wallingford sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
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 Wallingford
A heat pump in Wallingford
In December, the darkest month here, 12 panels in Wallingford make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Wallingford comes down to the tariff and the flow temperature rather than the roof.
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 Wallingford
Wallingford's July output, about 790 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.

Wallingford solar questions
How much electricity do solar panels make in Wallingford?
About 6,470 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Wallingford: 1,017 kWh per kWp, or 2.79 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
Is solar more expensive in Wallingford?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Wallingford, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,470 kWh a year here, which is what drives payback.
Which DNO covers Wallingford, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Wallingford. 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 Wallingford?
On the 12p export scenario, a 12-panel system in Wallingford sends about 5,531 kWh a year to the grid, worth around £664. The export rates table compares what each supplier pays.
How much solar does Wallingford get in December?
December is the low point: about 220 kWh from a 12-panel system in Wallingford, 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.

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.
