How Spennymoor compares
Small towns rarely get published solar figures, so here are the numbers for Spennymoor. It is one of 35 Durham towns we track, and it ranks joint 17th of 35 for solar yield, a town of 21,744 people in the House of Commons Library settlement data. PVGIS gives its roofs 945 kWh per kWp a year, 2.59 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £856 of year one benefit, £247 of it from your own generation and £609 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Spennymoor'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.
Spennymoor sits within County Durham, 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.

Generation is modelled from PVGIS satellite data for Spennymoor's own coordinates (54.70123, -1.59795), 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.
Connecting solar to the Spennymoor network
The distribution network operator (DNO) for Spennymoor is Northern Powergrid, which runs the North East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, Northern Powergrid only has to be told within 28 days after the system is commissioned.
Anything bigger is a G99 case and is applied for first. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.

Adding a heat pump or an EV charger in Spennymoor
A heat pump in Spennymoor
Solar and a heat pump pull in opposite directions through the year: Spennymoor's roofs make 950 kWh from November to February on a 12-panel system, and 2,910 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Spennymoor
From April to September, 69% of a Spennymoor roof's yearly output arrives, peaking at about 780 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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 Spennymoor
What could a roof in Spennymoor generate?
PVGIS puts a roof in Spennymoor at 945 kWh per kWp a year, 2.59 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,010 kWh a year, most of it between April and September.
What would 12 solar panels cost in Spennymoor?
£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 Spennymoor differs is output: about 6,010 kWh a year from that system.
Do I need permission from the DNO for solar in Spennymoor?
Usually not in advance. Northern Powergrid, the network operator for Spennymoor, 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. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection. "See our DNO explainer.
How much would export pay on a system in Spennymoor?
It is exported. With typical use and no battery, about 5,074 kWh of the 6,010 kWh a 12-panel system makes in Spennymoor goes to the grid, around £609 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 Spennymoor?
Yes, at a lower level. PVGIS gives Spennymoor 27.7 kWh per kWp in December and 31.8 in January, so a 12-panel system makes about 180 kWh and 200 kWh in those months, against 780 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Spennymoor compares with its neighbours
How the towns nearest Spennymoor compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Spennymoor |
|---|---|---|
| Spennymoor | 945 | this town |
| Ferryhill | 949 | +4 kWh |
| Brandon (County Durham) | 941 | −4 kWh |
| Bishop Auckland | 935 | −10 kWh |
| Shildon | 936 | −9 kWh |
| Durham | 942 | −3 kWh |
| Newton Aycliffe | 937 | −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.
