How Ashtead compares
Small towns rarely get published solar figures, so here are the numbers for Ashtead. It is one of 47 Surrey towns we track, and it ranks joint 33rd of 47 for solar yield, a town of 14,897 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,019 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 Ashtead'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.
Ashtead sits within Mole Valley, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Ashtead network
The distribution network operator (DNO) for Ashtead is UK Power Networks, which runs the South East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
Anything bigger is a G99 case and is applied for first. 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 Ashtead
A heat pump in Ashtead
Solar and a heat pump pull in opposite directions through the year: Ashtead's roofs make 1,090 kWh from November to February on a 12-panel system, and 3,070 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Ashtead
From April to September, 68% of a Ashtead roof's yearly output arrives, peaking at about 800 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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 Ashtead: your questions answered
What could a roof in Ashtead generate?
PVGIS puts a roof in Ashtead at 1,019 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,480 kWh a year, most of it between April and September.
What would 12 solar panels cost in Ashtead?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Ashtead differs is output: about 6,480 kWh a year from that system.
Do I need permission from the DNO for solar in Ashtead?
Usually not in advance. UK Power Networks, the network operator for Ashtead, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. 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. "See our DNO explainer.
How much would export pay on a system in Ashtead?
It is exported. With typical use and no battery, about 5,544 kWh of the 6,480 kWh a 12-panel system makes in Ashtead goes to the grid, around £665 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Ashtead?
Yes, at a lower level. PVGIS gives Ashtead 35.6 kWh per kWp in December and 38.5 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 800 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Ashtead compares with its neighbours
How the towns nearest Ashtead compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Ashtead |
|---|---|---|
| Ashtead | 1,019 | this town |
| Leatherhead | 1,030 | +11 kWh |
| Epsom | 1,018 | −1 kWh |
| Tadworth and Epsom Downs | 1,019 | level |
| Great Bookham and Fetcham | 1,024 | +5 kWh |
| Ewell | 1,017 | −2 kWh |
| Cobham | 1,025 | +6 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.
