How Castleford compares
Among the places we publish figures for, Castleford is one of 122 Yorkshire towns we track, and it ranks joint 40th of 122 for solar yield. It is a medium town in the House of Commons Library classification, with 47,678 residents, and its roofs see 2.64 peak sun hours a day across the year. That drives the standard 12 panel model to 6,118 kWh of generation, of which around 5,182 kWh is exported at 12p for £622 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
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 Castleford's own yield.
Planning applications here go through Wakefield; nationally, the House of Commons Library classes Castleford as a medium 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.

Northern Powergrid and your Castleford connection
Castleford is served by Northern Powergrid: the town's centre falls inside its Yorkshire 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 Northern Powergrid within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Above that, G99 means applying before the work is booked. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.

Beyond the panels: heating and car charging in Castleford
A heat pump in Castleford
In December, the darkest month here, 12 panels in Castleford make about 200 kWh. That is when a heat pump runs hardest, so its running cost in Castleford 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 Castleford
Castleford's May output, about 770 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).

Common questions about solar in Castleford
How much electricity do solar panels make in Castleford?
About 6,120 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Castleford: 962 kWh per kWp, or 2.64 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
Is solar more expensive in Castleford?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Castleford, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,120 kWh a year here, which is what drives payback.
Which DNO covers Castleford, and what does it need from me?
Northern Powergrid covers Castleford. A home system of up to 3.68kW per phase is notified to Northern Powergrid within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.
What could I earn from exporting in Castleford?
On the 12p export scenario, a 12-panel system in Castleford sends about 5,182 kWh a year to the grid, worth around £622. The export rates table compares what each supplier pays.
How much solar does Castleford get in December?
December is the low point: about 200 kWh from a 12-panel system in Castleford, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 1,010 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Castleford compares with its neighbours
How the towns nearest Castleford compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Castleford |
|---|---|---|
| Castleford | 962 | this town |
| Pontefract | 969 | +7 kWh |
| Normanton | 956 | −6 kWh |
| Featherstone | 965 | +3 kWh |
| Kippax | 953 | −9 kWh |
| Knottingley | 973 | +11 kWh |
| Garforth | 954 | −8 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.
