Against Great Britain as a whole: Chertsey makes 1,025 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Chertsey is 11% above it.
How Chertsey compares
Small towns rarely get published solar figures, so here are the numbers for Chertsey. It is one of 47 Surrey towns we track, and it ranks joint 17th of 47 for solar yield, a town of 15,252 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,025 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £917 of year one benefit, £247 of it from your own generation and £670 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Chertsey'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 Runnymede; nationally, the House of Commons Library classes Chertsey 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.

The network operator for Chertsey
Chertsey 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.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Chertsey
A heat pump in Chertsey
In December, the darkest month here, 12 panels in Chertsey make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Chertsey comes down to the tariff and the flow temperature rather than the roof.
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 Chertsey
Summer is where a car earns its place. In July, 12 panels in Chertsey make about 810 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).

Chertsey solar questions
How much energy would 12 solar panels make in Chertsey?
Chertsey averages 2.81 peak sun hours a day, which PVGIS turns into 1,025 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,520 kWh, 68% of it between April and September.
What does a typical solar system cost in Chertsey?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Chertsey, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,520 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Chertsey, and do I need a G99 application?
The operator is UK Power Networks. 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. 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Chertsey?
Around £670 a year at 12p per kWh, for the roughly 5,582 kWh a 12-panel system in Chertsey 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 Chertsey in the winter months?
December is the weakest month in Chertsey: about 230 kWh from 12 panels, against 810 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Chertsey compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Chertsey.

| Addlestone | 1,024 | −1 kWh |
| Staines-upon-Thames | 1,024 | −1 kWh |
| Weybridge | 1,025 | level |
| West Byfleet, Sheerwater and New Haw | 1,026 | +1 kWh |
| Byfleet | 1,024 | −1 kWh |
| Egham | 1,024 | −1 kWh |
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.
