How Crawley compares
Crawley is one of 33 Sussex towns we track, and it ranks 32nd of 33 for solar yield. The House of Commons Library settlement data classes it as a large town of 126,260 people. At 1,035 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.9 years on the 12p scenario: £924 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Crawley'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.
Crawley is its own local planning authority area, and its House of Commons Library settlement class is large 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 Crawley
The distribution network operator (DNO) for Crawley is UK Power Networks, which runs the South East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
Above that, G99 means applying before the work is booked. 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 Crawley
A heat pump in Crawley
Heating demand peaks when solar is weakest. In Crawley, a 12-panel system makes about 240 kWh in December and 250 kWh in January, a fraction of its 820 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Crawley
Crawley's July output, about 820 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar panel servicing and repair in Crawley
If a system in Crawley is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Crawley: your questions answered
How much energy would 12 solar panels make in Crawley?
Crawley averages 2.84 peak sun hours a day, which PVGIS turns into 1,035 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,580 kWh, 68% of it between April and September.
Is solar more expensive in Crawley?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Crawley, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,580 kWh a year here, which is what drives payback.
Who is the network operator in Crawley, 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 could I earn from exporting in Crawley?
On the 12p export scenario, a 12-panel system in Crawley sends about 5,646 kWh a year to the grid, worth around £678. The export rates table compares what each supplier pays.
How does solar perform in Crawley in the winter months?
December is the weakest month in Crawley: about 240 kWh from 12 panels, against 820 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Crawley 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 Crawley |
|---|---|---|
| Crawley | 1,035 | this town |
| Horley | 1,032 | −3 kWh |
| Horsham | 1,061 | +26 kWh |
| East Grinstead | 1,034 | −1 kWh |
| Redhill | 1,033 | −2 kWh |
| Reigate | 1,040 | +5 kWh |
| Haywards Heath | 1,088 | +53 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.
