How Rusthall and Langton Green compares
Small towns rarely get published solar figures, so here are the numbers for Rusthall and Langton Green. It is one of 44 Kent towns we track, and it ranks joint 28th of 44 for solar yield, a town of 7,872 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,051 kWh per kWp a year, 2.88 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £937 of year one benefit, £247 of it from your own generation and £690 from export at 12p.
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 Rusthall and Langton Green's own yield.
Planning applications here go through Tunbridge Wells; nationally, the House of Commons Library classes Rusthall and Langton Green as a small 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.

The network operator for Rusthall and Langton Green
On NESO's licence-area map, Rusthall and Langton Green 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.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Rusthall and Langton Green
A heat pump in Rusthall and Langton Green
In December, the darkest month here, 12 panels in Rusthall and Langton Green make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Rusthall and Langton Green comes down to the tariff and the flow temperature rather than the roof.
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 Rusthall and Langton Green
Summer is where a car earns its place. In July, 12 panels in Rusthall and Langton Green make about 830 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Common questions about solar in Rusthall and Langton Green
How much energy would 12 solar panels make in Rusthall and Langton Green?
Rusthall and Langton Green averages 2.88 peak sun hours a day, which PVGIS turns into 1,051 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,680 kWh, 68% of it between April and September.
What does a typical solar system cost in Rusthall and Langton Green?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Rusthall and Langton Green, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,680 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Rusthall and Langton Green, 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 happens to the solar I do not use in Rusthall and Langton Green?
Around £690 a year at 12p per kWh, for the roughly 5,748 kWh a 12-panel system in Rusthall and Langton Green exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Rusthall and Langton Green in the winter months?
December is the weakest month in Rusthall and Langton Green: about 240 kWh from 12 panels, against 830 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Rusthall and Langton Green 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 Rusthall and Langton Green |
|---|---|---|
| Rusthall and Langton Green | 1,051 | this town |
| Royal Tunbridge Wells | 1,054 | +3 kWh |
| Southborough | 1,051 | level |
| Tonbridge | 1,051 | level |
| Crowborough | 1,054 | +3 kWh |
| Paddock Wood | 1,071 | +20 kWh |
| Edenbridge | 1,050 | −1 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.
