How Thrapston compares
Small towns rarely get published solar figures, so here are the numbers for Thrapston. It is one of 16 Northamptonshire towns we track, and it ranks joint 1st of 16 for solar yield, a town of 7,638 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,031 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £921 of year one benefit, £247 of it from your own generation and £674 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Thrapston'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.
Planning applications here go through North Northamptonshire; nationally, the House of Commons Library classes Thrapston 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.

NGED and your Thrapston connection
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Thrapston, as part of its East Midlands licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means NGED is notified within 28 days of switch-on rather than asked beforehand.
Larger systems go through G99 instead, applied for before installation. On timing: NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Thrapston
A heat pump in Thrapston
In December, the darkest month here, 12 panels in Thrapston make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Thrapston comes down to the tariff and the flow temperature rather 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 Thrapston
Summer is where a car earns its place. In July, 12 panels in Thrapston make about 800 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.
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 in Thrapston: your questions answered
How much energy would 12 solar panels make in Thrapston?
Thrapston averages 2.83 peak sun hours a day, which PVGIS turns into 1,031 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,560 kWh, 67% of it between April and September.
What does a typical solar system cost in Thrapston?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Thrapston, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,560 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Thrapston, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). 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. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Thrapston?
Around £674 a year at 12p per kWh, for the roughly 5,620 kWh a 12-panel system in Thrapston 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 Thrapston in the winter months?
December is the weakest month in Thrapston: about 240 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.
How Thrapston 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 Thrapston |
|---|---|---|
| Thrapston | 1,031 | this town |
| Raunds | 1,031 | level |
| Irthlingborough | 1,021 | −10 kWh |
| Higham Ferrers | 1,024 | −7 kWh |
| Burton Latimer | 1,021 | −10 kWh |
| Kettering | 1,022 | −9 kWh |
| Rushden | 1,026 | −5 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.
