How Redhill compares
Among the places we publish figures for, Redhill is one of 47 Surrey towns we track, and it ranks 7th of 47 for solar yield. It is a medium town in the House of Commons Library classification, with 35,416 residents, and its roofs see 2.83 peak sun hours a day across the year. That drives the standard 12 panel model to 6,570 kWh of generation, of which around 5,633 kWh is exported at 12p for £676 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Redhill's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Redhill sits within Reigate and Banstead, 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.

Generation is modelled from PVGIS satellite data for Redhill's own coordinates (51.23455, -0.17057), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Connecting solar to the Redhill network
UK Power Networks owns and runs the local electricity network in Redhill, as part of its 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.
Anything bigger is a G99 case and is applied for 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.

Adding a heat pump or an EV charger in Redhill
A heat pump in Redhill
Solar and a heat pump pull in opposite directions through the year: Redhill's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,120 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Redhill
From April to September, 68% of a Redhill roof's yearly output arrives, peaking at about 820 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.
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.

Redhill solar questions
What could a roof in Redhill generate?
PVGIS puts a roof in Redhill at 1,033 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,570 kWh a year, most of it between April and September.
How much are solar panels in Redhill?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Redhill before a battery. What Redhill changes is the return, about 6,570 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Redhill?
Usually not in advance. UK Power Networks, the network operator for Redhill, 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 can I earn from exporting solar in Redhill?
With typical use and no battery, a 12-panel system in Redhill exports about 5,633 kWh a year. At 12p per kWh that is roughly £676; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Redhill?
Yes, at a lower level. PVGIS gives Redhill 34.9 kWh per kWp in December and 38.3 in January, so a 12-panel system makes about 220 kWh and 240 kWh in those months, against 820 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Redhill compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Redhill.
| Town | kWh per kWp a year | vs Redhill |
|---|---|---|
| Redhill | 1,033 | this town |
| Reigate | 1,040 | +7 kWh |
| South Merstham | 1,029 | −4 kWh |
| Horley | 1,032 | −1 kWh |
| Caterham | 1,031 | −2 kWh |
| Tadworth and Epsom Downs | 1,019 | −14 kWh |
| Banstead | 1,016 | −17 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.
