How Ascot and Sunningdale compares
Small towns rarely get published solar figures, so here are the numbers for Ascot and Sunningdale. It is one of 20 Berkshire towns we track, and it ranks 10th of 20 for solar yield, a town of 15,823 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,023 kWh per kWp a year, 2.80 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £915 of year one benefit, £247 of it from your own generation and £668 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Ascot and Sunningdale'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 Ascot and Sunningdale sits with Windsor and Maidenhead, 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 Ascot and Sunningdale connection
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in Ascot and Sunningdale, as part of its Southern England licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: SSEN is notified within 28 days of commissioning and nothing has to be approved first.
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 Ascot and Sunningdale
A heat pump in Ascot and Sunningdale
Heating demand peaks when solar is weakest. In Ascot and Sunningdale, a 12-panel system makes about 230 kWh in December and 250 kWh in January, a fraction of its 800 kWh in July, which is why a heat pump here is costed on its tariff first.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Ascot and Sunningdale
Summer is where a car earns its place. In July, 12 panels in Ascot and Sunningdale 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Ascot and Sunningdale solar questions
How much electricity do solar panels make in Ascot and Sunningdale?
About 6,510 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Ascot and Sunningdale: 1,023 kWh per kWp, or 2.80 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
What does a typical solar system cost in Ascot and Sunningdale?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Ascot and Sunningdale, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,510 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Ascot and Sunningdale, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Ascot and Sunningdale. 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 happens to the solar I do not use in Ascot and Sunningdale?
Around £668 a year at 12p per kWh, for the roughly 5,570 kWh a 12-panel system in Ascot and Sunningdale 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 Ascot and Sunningdale get in December?
December is the low point: about 230 kWh from a 12-panel system in Ascot and Sunningdale, 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 Ascot and Sunningdale 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 Ascot and Sunningdale |
|---|---|---|
| Ascot and Sunningdale | 1,023 | this town |
| North Ascot | 1,020 | −3 kWh |
| West End and Chobham | 1,025 | +2 kWh |
| Bracknell | 1,008 | −15 kWh |
| Egham | 1,024 | +1 kWh |
| Old Windsor and Wraysbury | 1,024 | +1 kWh |
| Windsor | 1,021 | −2 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.
