How Brackley compares
Small towns rarely get published solar figures, so here are the numbers for Brackley. It is one of 16 Northamptonshire towns we track, and it ranks 15th of 16 for solar yield, a town of 16,882 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,016 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £910 of year one benefit, £247 of it from your own generation and £663 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 Brackley's own yield.
Any planning application in Brackley sits with West Northamptonshire, and its official House of Commons Library settlement class is 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 Brackley
The distribution network operator (DNO) for Brackley is National Grid Electricity Distribution (NGED), which runs the East Midlands licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, NGED only has to be told within 28 days after the system is commissioned.
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.

Beyond the panels: heating and car charging in Brackley
A heat pump in Brackley
Heating demand peaks when solar is weakest. In Brackley, a 12-panel system makes about 230 kWh in December and 250 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Brackley
Brackley'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.
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 panel servicing and repair in Brackley
If a system in Brackley is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Brackley: your questions answered
How much energy would 12 solar panels make in Brackley?
Brackley averages 2.78 peak sun hours a day, which PVGIS turns into 1,016 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,460 kWh, 68% of it between April and September.
Is solar more expensive in Brackley?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Brackley, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,460 kWh a year here, which is what drives payback.
Who is the network operator in Brackley, 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 could I earn from exporting in Brackley?
On the 12p export scenario, a 12-panel system in Brackley sends about 5,525 kWh a year to the grid, worth around £663. The export rates table compares what each supplier pays.
How does solar perform in Brackley in the winter months?
December is the weakest month in Brackley: about 230 kWh from 12 panels, against 790 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Brackley 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 Brackley |
|---|---|---|
| Brackley | 1,016 | this town |
| Buckingham | 1,014 | −2 kWh |
| Banbury | 1,013 | −3 kWh |
| Bicester | 1,020 | +4 kWh |
| Towcester | 1,022 | +6 kWh |
| Kidlington | 1,014 | −2 kWh |
| Daventry | 1,012 | −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.

Why your inverter is smaller than your panel array, and why that is correct
More panel capacity than inverter capacity is a deliberate design choice.
