Against Great Britain as a whole: Corby makes 1,019 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Corby is 10% above it.
How Corby compares
Corby is one of 16 Northamptonshire towns we track, and it ranks 13th of 16 for solar yield. The House of Commons Library settlement data classes it as a large town of 70,568 people. At 1,019 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.0 years on the 12p scenario: £912 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Corby'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 Corby as a large 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.

Generation is modelled from PVGIS satellite data for Corby's own coordinates (52.49238, -0.69101), 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.
NGED and your Corby connection
Corby is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its East Midlands licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to NGED 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: 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 Corby
A heat pump in Corby
In December, the darkest month here, 12 panels in Corby make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Corby comes down to the tariff and the flow temperature rather 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 Corby
Summer is where a car earns its place. In July, 12 panels in Corby make about 790 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 Corby: your questions answered
How much electricity do solar panels make in Corby?
About 6,480 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Corby: 1,019 kWh per kWp, or 2.79 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
What does a typical solar system cost in Corby?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Corby, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,480 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Corby, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Corby. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What happens to the solar I do not use in Corby?
Around £665 a year at 12p per kWh, for the roughly 5,544 kWh a 12-panel system in Corby exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Corby get in December?
December is the low point: about 240 kWh from a 12-panel system in Corby, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,110 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Corby 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 Corby |
|---|---|---|
| Corby | 1,019 | this town |
| Desborough | 1,023 | +4 kWh |
| Rothwell (North Northamptonshire) | 1,023 | +4 kWh |
| Kettering | 1,022 | +3 kWh |
| Burton Latimer | 1,021 | +2 kWh |
| Thrapston | 1,031 | +12 kWh |
| Market Harborough | 1,015 | −4 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
