Against Great Britain as a whole: Larkfield makes 1,059 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Larkfield is 14% above it.
How Larkfield compares
Among the places we publish figures for, Larkfield is one of 44 Kent towns we track, and it ranks joint 20th of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 26,840 residents, and its roofs see 2.90 peak sun hours a day across the year. That drives the standard 12 panel model to 6,735 kWh of generation, of which around 5,799 kWh is exported at 12p for £696 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Larkfield'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.
Tonbridge and Malling is the planning authority covering Larkfield, which the House of Commons Library classes 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.

Who runs the grid in Larkfield
UK Power Networks owns and runs the local electricity network in Larkfield, 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.
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 Larkfield
A heat pump in Larkfield
A heat pump does most of its work from November to February. Over those four months, 12 panels in Larkfield make about 1,140 kWh, against 3,180 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Larkfield
A 12-panel roof in Larkfield makes about 830 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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 Larkfield: your questions answered
What does a solar panel system produce in Larkfield?
Each kWp of panels in Larkfield makes 1,059 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,740 kWh, from about 250 kWh in December up to 830 kWh in July.
What would 12 solar panels cost in Larkfield?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Larkfield differs is output: about 6,740 kWh a year from that system.
Would a system in Larkfield need approval from the network operator?
Larkfield 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 would export pay on a system in Larkfield?
It is exported. With typical use and no battery, about 5,799 kWh of the 6,740 kWh a 12-panel system makes in Larkfield goes to the grid, around £696 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Larkfield in winter?
It works, but the year is lopsided. 68% of a Larkfield roof's output lands between April and September; the four months from November to February give about 1,140 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Larkfield compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Larkfield.
| Town | kWh per kWp a year | vs Larkfield |
|---|---|---|
| Larkfield | 1,059 | this town |
| Snodland | 1,051 | −8 kWh |
| Kings Hill | 1,059 | level |
| Maidstone | 1,056 | −3 kWh |
| Chatham | 1,043 | −16 kWh |
| Bearsted | 1,055 | −4 kWh |
| Rochester | 1,043 | −16 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
