How Castle Donington compares
Small towns rarely get published solar figures, so here are the numbers for Castle Donington. It is one of 26 Leicestershire towns we track, and it ranks joint 9th of 26 for solar yield, a town of 8,194 people in the House of Commons Library settlement data. PVGIS gives its roofs 991 kWh per kWp a year, 2.71 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £891 of year one benefit, £247 of it from your own generation and £644 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Castle Donington'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 West Leicestershire; nationally, the House of Commons Library classes Castle Donington 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.

The network operator for Castle Donington
The distribution network operator (DNO) for Castle Donington 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.
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.

Heat pumps and EV charging in Castle Donington
A heat pump in Castle Donington
Heating demand peaks when solar is weakest. In Castle Donington, a 12-panel system makes about 220 kWh in December and 230 kWh in January, a fraction of its 780 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Castle Donington
Castle Donington's May output, about 780 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.

Solar panel servicing and repair in Castle Donington
If a system in Castle Donington is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Castle Donington: your questions answered
How much energy would 12 solar panels make in Castle Donington?
Castle Donington averages 2.71 peak sun hours a day, which PVGIS turns into 991 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,300 kWh, 68% of it between April and September.
Is solar more expensive in Castle Donington?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Castle Donington, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,300 kWh a year here, which is what drives payback.
Who is the network operator in Castle Donington, 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 Castle Donington?
On the 12p export scenario, a 12-panel system in Castle Donington sends about 5,366 kWh a year to the grid, worth around £644. The export rates table compares what each supplier pays.
How does solar perform in Castle Donington in the winter months?
December is the weakest month in Castle Donington: about 220 kWh from 12 panels, against 780 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Castle Donington 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 Castle Donington |
|---|---|---|
| Castle Donington | 991 | this town |
| Long Eaton | 986 | −5 kWh |
| Sandiacre | 981 | −10 kWh |
| Shepshed | 986 | −5 kWh |
| Stapleford | 980 | −11 kWh |
| Derby | 980 | −11 kWh |
| East Leake | 986 | −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.
