Against Great Britain as a whole: Crowborough makes 1,054 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Crowborough is 14% above it.
How Crowborough compares
Small towns rarely get published solar figures, so here are the numbers for Crowborough. It is one of 33 Sussex towns we track, and it ranks 31st of 33 for solar yield, a town of 22,977 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,054 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £939 of year one benefit, £247 of it from your own generation and £692 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Crowborough'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 Crowborough sits with Wealden, 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.

The network operator for Crowborough
Crowborough 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.
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 Crowborough
A heat pump in Crowborough
In December, the darkest month here, 12 panels in Crowborough make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Crowborough comes down to the tariff and the flow temperature rather than the roof.
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 Crowborough
Summer is where a car earns its place. In July, 12 panels in Crowborough make about 830 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.
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 Crowborough: your questions answered
How much energy would 12 solar panels make in Crowborough?
Crowborough averages 2.89 peak sun hours a day, which PVGIS turns into 1,054 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,700 kWh, 68% of it between April and September.
What does a typical solar system cost in Crowborough?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Crowborough, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,700 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Crowborough, 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 Crowborough?
Around £692 a year at 12p per kWh, for the roughly 5,767 kWh a 12-panel system in Crowborough 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 Crowborough in the winter months?
December is the weakest month in Crowborough: about 240 kWh from 12 panels, against 830 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Crowborough 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 Crowborough |
|---|---|---|
| Crowborough | 1,054 | this town |
| Rusthall and Langton Green | 1,051 | −3 kWh |
| Uckfield | 1,120 | +66 kWh |
| Heathfield | 1,110 | +56 kWh |
| Royal Tunbridge Wells | 1,054 | level |
| Southborough | 1,051 | −3 kWh |
| East Grinstead | 1,034 | −20 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.
