How Bexley compares
Bexley is one of 44 Kent towns we track, and it ranks 38th of 44 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 255,710, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,042 kWh per kWp a year, 2.85 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 £683.
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 Bexley's own yield.
Bexley is its own local planning authority area, and its House of Commons Library settlement class is 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.

Generation is modelled from PVGIS satellite data for Bexley's own coordinates (51.45984, 0.13727), 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.
UK Power Networks and your Bexley connection
Bexley is served by UK Power Networks: the town's centre falls inside its London 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.
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.

Beyond the panels: heating and car charging in Bexley
A heat pump in Bexley
Heating demand peaks when solar is weakest. In Bexley, 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.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Bexley
Bexley'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.
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).

Solar panel servicing and repair in Bexley
If a system in Bexley is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Bexley: your questions answered
How much energy would 12 solar panels make in Bexley?
Bexley averages 2.85 peak sun hours a day, which PVGIS turns into 1,042 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,630 kWh, 68% of it between April and September.
Is solar more expensive in Bexley?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Bexley, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,630 kWh a year here, which is what drives payback.
Who is the network operator in Bexley, 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 Bexley?
On the 12p export scenario, a 12-panel system in Bexley sends about 5,690 kWh a year to the grid, worth around £683. The export rates table compares what each supplier pays.
How does solar perform in Bexley in the winter months?
December is the weakest month in Bexley: 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 Bexley compares with its neighbours
How the towns nearest Bexley compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Bexley |
|---|---|---|
| Bexley | 1,042 | this town |
| Greenwich | 1,036 | −6 kWh |
| Dartford | 1,039 | −3 kWh |
| Swanley | 1,033 | −9 kWh |
| Aveley | 1,049 | +7 kWh |
| Barking and Dagenham | 1,040 | −2 kWh |
| Chafford Hundred, West Thurrock and Purfleet-on-Thames | 1,052 | +10 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.
