How Richmond upon Thames compares
Richmond upon Thames is one of 23 Middlesex towns we track, and it ranks joint 15th of 23 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 194,326, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,024 kWh per kWp a year, 2.81 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 £669.
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 Richmond upon Thames' own yield.
Planning applications in Richmond upon Thames 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.

Generation is modelled from PVGIS satellite data for Richmond upon Thames' own coordinates (51.44602, -0.32393), 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.
Who runs the grid in Richmond upon Thames
UK Power Networks owns and runs the local electricity network in Richmond upon Thames, as part of its South East England licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: UK Power Networks is notified within 28 days of commissioning and nothing has to be approved first.
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.

Beyond the panels: heating and car charging in Richmond upon Thames
A heat pump in Richmond upon Thames
A heat pump does most of its work from November to February. Over those four months, 12 panels in Richmond upon Thames make about 1,110 kWh, against 3,080 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Richmond upon Thames
From April to September, 68% of a Richmond upon Thames 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.
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.

Solar in Richmond upon Thames: your questions answered
What does a solar panel system produce in Richmond upon Thames?
Each kWp of panels in Richmond upon Thames makes 1,024 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,510 kWh, from about 230 kWh in December up to 800 kWh in July.
How much are solar panels in Richmond upon Thames?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Richmond upon Thames before a battery. What Richmond upon Thames changes is the return, about 6,510 kWh a year from that system, and your design call prices your actual roof.
Would a system in Richmond upon Thames need approval from the network operator?
Richmond upon Thames is on UK Power Networks' network (South East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Richmond upon Thames?
With typical use and no battery, a 12-panel system in Richmond upon Thames exports about 5,576 kWh a year. At 12p per kWh that is roughly £669; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Richmond upon Thames in winter?
It works, but the year is lopsided. 68% of a Richmond upon Thames roof's output lands between April and September; the four months from November to February give about 1,110 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
