How Croydon compares
Croydon is one of 47 Surrey towns we track, and it ranks joint 45th of 47 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 407,821, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,015 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons, and on the 12p scenario about £247 of the year one benefit comes from solar you use yourself, with export income adding £662.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Croydon'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 in Croydon go to its own council, and the House of Commons Library classes it as a core city.
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.

Connecting solar to the Croydon network
Croydon is served by UK Power Networks: the town's centre falls inside its South East England licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to UK Power Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
A bigger inverter or battery output needs a G99 application in advance. 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 Croydon
A heat pump in Croydon
Solar and a heat pump pull in opposite directions through the year: Croydon's roofs make 1,080 kWh from November to February on a 12-panel system, and 3,070 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 Croydon
From April to September, 68% of a Croydon roof's yearly output arrives, peaking at about 800 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.
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 Croydon: your questions answered
What could a roof in Croydon generate?
PVGIS puts a roof in Croydon at 1,015 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,460 kWh a year, most of it between April and September.
How much are solar panels in Croydon?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Croydon before a battery. What Croydon changes is the return, about 6,460 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Croydon?
Usually not in advance. UK Power Networks, the network operator for Croydon, 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 Croydon?
With typical use and no battery, a 12-panel system in Croydon exports about 5,519 kWh a year. At 12p per kWh that is roughly £662; 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 Croydon?
Yes, at a lower level. PVGIS gives Croydon 35.8 kWh per kWp in December and 37.1 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 800 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Croydon 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 Croydon |
|---|---|---|
| Croydon | 1,015 | this town |
| Warlingham | 1,017 | +2 kWh |
| Sutton | 1,015 | level |
| Caterham | 1,031 | +16 kWh |
| Banstead | 1,016 | +1 kWh |
| Merton | 1,022 | +7 kWh |
| Bromley | 1,023 | +8 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.
