How Kettering compares
Kettering is one of 16 Northamptonshire towns we track, and it ranks joint 8th of 16 for solar yield. The House of Commons Library settlement data classes it as a large town of 66,644 people. At 1,022 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.0 years on the 12p scenario: £914 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Kettering's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Planning applications here go through North Northamptonshire; nationally, the House of Commons Library classes Kettering 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 Kettering's own coordinates (52.39594, -0.71595), 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.
The network operator for Kettering
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Kettering, 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.
Above that, G99 means applying before the work is booked. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Kettering
A heat pump in Kettering
In December, the darkest month here, 12 panels in Kettering make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Kettering 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 Kettering
Kettering's July output, about 790 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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.

Kettering solar questions
How much electricity do solar panels make in Kettering?
About 6,500 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Kettering: 1,022 kWh per kWp, or 2.80 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
Is solar more expensive in Kettering?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Kettering, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,500 kWh a year here, which is what drives payback.
Which DNO covers Kettering, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Kettering. 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 could I earn from exporting in Kettering?
On the 12p export scenario, a 12-panel system in Kettering sends about 5,563 kWh a year to the grid, worth around £668. The export rates table compares what each supplier pays.
How much solar does Kettering get in December?
December is the low point: about 240 kWh from a 12-panel system in Kettering, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,130 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Kettering 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 Kettering |
|---|---|---|
| Kettering | 1,022 | this town |
| Burton Latimer | 1,021 | −1 kWh |
| Rothwell (North Northamptonshire) | 1,023 | +1 kWh |
| Desborough | 1,023 | +1 kWh |
| Wellingborough | 1,022 | level |
| Irthlingborough | 1,021 | −1 kWh |
| Corby | 1,019 | −3 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.
