How West Molesey compares
Among the places we publish figures for, West Molesey is one of 47 Surrey towns we track, and it ranks joint 33rd of 47 for solar yield. It is a medium town in the House of Commons Library classification, with 46,837 residents, and its roofs see 2.79 peak sun hours a day across the year. That drives the standard 12 panel model to 6,481 kWh of generation, of which around 5,544 kWh is exported at 12p for £665 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on West Molesey'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.
West Molesey sits within Elmbridge, its local planning authority, and the House of Commons Library classes it as a medium 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 West Molesey network
West Molesey sits in UK Power Networks' South East England licence area, so UK Power Networks 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, UK Power Networks only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. 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 West Molesey
A heat pump in West Molesey
Solar and a heat pump pull in opposite directions through the year: West Molesey'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 West Molesey
From April to September, 68% of a West Molesey 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 West Molesey: your questions answered
What could a roof in West Molesey generate?
PVGIS puts a roof in West Molesey 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 West Molesey?
£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 West Molesey differs is output: about 6,480 kWh a year from that system.
Do I need permission from the DNO for solar in West Molesey?
Usually not in advance. UK Power Networks, the network operator for West Molesey, 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 West Molesey?
It is exported. With typical use and no battery, about 5,544 kWh of the 6,480 kWh a 12-panel system makes in West Molesey 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 West Molesey?
Yes, at a lower level. PVGIS gives West Molesey 35.5 kWh per kWp in December and 38.4 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 West Molesey 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 West Molesey |
|---|---|---|
| West Molesey | 1,019 | this town |
| Esher | 1,024 | +5 kWh |
| Kingston upon Thames | 1,018 | −1 kWh |
| Walton-on-Thames | 1,025 | +6 kWh |
| Hersham | 1,025 | +6 kWh |
| Sunbury-on-Thames | 1,024 | +5 kWh |
| Cobham | 1,025 | +6 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.

Do solar panels need direct sunlight? Not really, and here is why
No. Solar cells respond to light hitting them, not to a clear line of sight to the sun.
