How Cranleigh compares
Small towns rarely get published solar figures, so here are the numbers for Cranleigh. It is one of 47 Surrey towns we track, and it ranks 1st of 47 for solar yield, a town of 11,292 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,050 kWh per kWp a year, 2.88 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £936 of year one benefit, £247 of it from your own generation and £689 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Cranleigh's own yield.
Any planning application in Cranleigh sits with Waverley, 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.

UK Power Networks and your Cranleigh connection
The distribution network operator (DNO) for Cranleigh 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.
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.

Beyond the panels: heating and car charging in Cranleigh
A heat pump in Cranleigh
Heating demand peaks when solar is weakest. In Cranleigh, a 12-panel system makes about 240 kWh in December and 260 kWh in January, a fraction of its 820 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Cranleigh
Summer is where a car earns its place. In July, 12 panels in Cranleigh make about 820 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).

Common questions about solar in Cranleigh
How much electricity do solar panels make in Cranleigh?
About 6,680 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Cranleigh: 1,050 kWh per kWp, or 2.88 peak sun hours a day on average. July is the strongest month, at about 820 kWh.
What does a typical solar system cost in Cranleigh?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Cranleigh, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,680 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Cranleigh, and what does it need from me?
UK Power Networks covers Cranleigh. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What happens to the solar I do not use in Cranleigh?
Around £689 a year at 12p per kWh, for the roughly 5,741 kWh a 12-panel system in Cranleigh exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Cranleigh get in December?
December is the low point: about 240 kWh from a 12-panel system in Cranleigh, on PVGIS data, rising to 820 kWh in July. From November to February the same system makes about 1,140 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Cranleigh compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Cranleigh.
| Town | kWh per kWp a year | vs Cranleigh |
|---|---|---|
| Cranleigh | 1,050 | this town |
| Godalming | 1,025 | −25 kWh |
| Farncombe | 1,034 | −16 kWh |
| Guildford | 1,028 | −22 kWh |
| Horsham | 1,061 | +11 kWh |
| Billingshurst | 1,079 | +29 kWh |
| Dorking | 1,036 | −14 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.
