How Royal Wootton Bassett compares
Small towns rarely get published solar figures, so here are the numbers for Royal Wootton Bassett. It is one of 20 Wiltshire towns we track, and it ranks joint 14th of 20 for solar yield, a town of 13,146 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,018 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 £912 of year one benefit, £247 of it from your own generation and £665 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Royal Wootton Bassett'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.
Planning applications here go through Wiltshire; nationally, the House of Commons Library classes Royal Wootton Bassett as a 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 Royal Wootton Bassett connection
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in Royal Wootton Bassett, as part of its 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.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Royal Wootton Bassett
A heat pump in Royal Wootton Bassett
Heating demand peaks when solar is weakest. In Royal Wootton Bassett, a 12-panel system makes about 230 kWh in December and 240 kWh in January, a fraction of its 800 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 Royal Wootton Bassett
Summer is where a car earns its place. In July, 12 panels in Royal Wootton Bassett make about 800 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.

Royal Wootton Bassett solar questions
How much energy would 12 solar panels make in Royal Wootton Bassett?
Royal Wootton Bassett averages 2.79 peak sun hours a day, which PVGIS turns into 1,018 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,470 kWh, 68% of it between April and September.
What does a typical solar system cost in Royal Wootton Bassett?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Royal Wootton Bassett, 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.
Who is the network operator in Royal Wootton Bassett, and do I need a G99 application?
The operator is Scottish and Southern Electricity Networks (SSEN). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Royal Wootton Bassett?
Around £665 a year at 12p per kWh, for the roughly 5,538 kWh a 12-panel system in Royal Wootton Bassett exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Royal Wootton Bassett in the winter months?
December is the weakest month in Royal Wootton Bassett: about 230 kWh from 12 panels, against 800 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Royal Wootton Bassett 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 Royal Wootton Bassett |
|---|---|---|
| Royal Wootton Bassett | 1,018 | this town |
| Wroughton | 1,019 | +1 kWh |
| Swindon | 1,018 | level |
| Stratton St Margaret | 1,020 | +2 kWh |
| Calne | 1,013 | −5 kWh |
| Malmesbury | 1,018 | level |
| Highworth | 1,018 | level |
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.
