How Desborough compares
Small towns rarely get published solar figures, so here are the numbers for Desborough. It is one of 16 Northamptonshire towns we track, and it ranks joint 6th of 16 for solar yield, a town of 11,866 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,023 kWh per kWp a year, 2.80 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £915 of year one benefit, £247 of it from your own generation and £668 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Desborough'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.
Desborough sits within North Northamptonshire, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Desborough network
The distribution network operator (DNO) for Desborough is National Grid Electricity Distribution (NGED), which runs the 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.
A bigger inverter or battery output needs a G99 application in advance. 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 Desborough
A heat pump in Desborough
Solar and a heat pump pull in opposite directions through the year: Desborough's roofs make 1,110 kWh from November to February on a 12-panel system, and 3,060 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Desborough
A 12-panel roof in Desborough makes about 790 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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.

Common questions about solar in Desborough
What could a roof in Desborough generate?
PVGIS puts a roof in Desborough at 1,023 kWh per kWp a year, 2.80 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,510 kWh a year, most of it between April and September.
What would 12 solar panels cost in Desborough?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Desborough differs is output: about 6,510 kWh a year from that system.
Do I need permission from the DNO for solar in Desborough?
Usually not in advance. NGED, the network operator for Desborough, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much would export pay on a system in Desborough?
It is exported. With typical use and no battery, about 5,570 kWh of the 6,510 kWh a 12-panel system makes in Desborough goes to the grid, around £668 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Desborough?
Yes, at a lower level. PVGIS gives Desborough 36.7 kWh per kWp in December and 38.4 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 790 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Desborough compares with its neighbours
How the towns nearest Desborough compare on the same PVGIS settings, closest first.

| Market Harborough | 1,015 | −8 kWh |

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
