How Kingston upon Thames compares
Kingston upon Thames is one of 47 Surrey towns we track, and it ranks joint 38th of 47 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 171,018, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,018 kWh per kWp a year, 2.79 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 £665.
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 Kingston upon Thames' own yield.
Kingston upon Thames 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.

The network operator for Kingston upon Thames
On NESO's licence-area map, Kingston upon Thames is in South East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
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 Kingston upon Thames
A heat pump in Kingston upon Thames
Heating demand peaks when solar is weakest. In Kingston upon Thames, a 12-panel system makes about 230 kWh in December and 240 kWh in January, a fraction of its 800 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 Kingston upon Thames
Kingston upon Thames' July output, about 800 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.
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.

Common questions about solar in Kingston upon Thames
How much energy would 12 solar panels make in Kingston upon Thames?
Kingston upon Thames averages 2.79 peak sun hours a day, which PVGIS turns into 1,018 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,470 kWh, 68% of it between April and September.
Is solar more expensive in Kingston upon Thames?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Kingston upon Thames, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,470 kWh a year here, which is what drives payback.
Who is the network operator in Kingston upon Thames, 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 Kingston upon Thames?
On the 12p export scenario, a 12-panel system in Kingston upon Thames sends about 5,538 kWh a year to the grid, worth around £665. The export rates table compares what each supplier pays.
How does solar perform in Kingston upon Thames in the winter months?
December is the weakest month in Kingston upon Thames: about 230 kWh from 12 panels, against 800 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
