How Seaton Delaval compares
Small towns rarely get published solar figures, so here are the numbers for Seaton Delaval. It is one of 18 Northumberland towns we track, and it ranks 8th of 18 for solar yield, a town of 8,106 people in the House of Commons Library settlement data. PVGIS gives its roofs 967 kWh per kWp a year, 2.65 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £873 of year one benefit, £247 of it from your own generation and £626 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Seaton Delaval'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.
Seaton Delaval sits within Northumberland, 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 Seaton Delaval network
Seaton Delaval is served by Northern Powergrid: the town's centre falls inside its North East England 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.
A bigger inverter or battery output needs a G99 application in advance. Northern Powergrid publishes a guaranteed standard of 45 working days to quote for a low voltage generation connection.

Heat pumps and EV charging in Seaton Delaval
A heat pump in Seaton Delaval
Solar and a heat pump pull in opposite directions through the year: Seaton Delaval's roofs make 990 kWh from November to February on a 12-panel system, and 2,960 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 Seaton Delaval
From April to September, 69% of a Seaton Delaval roof's yearly output arrives, peaking at about 790 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.
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).

Seaton Delaval solar questions
What could a roof in Seaton Delaval generate?
PVGIS puts a roof in Seaton Delaval at 967 kWh per kWp a year, 2.65 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,150 kWh a year, most of it between April and September.
What would 12 solar panels cost in Seaton Delaval?
£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 Seaton Delaval differs is output: about 6,150 kWh a year from that system.
Do I need permission from the DNO for solar in Seaton Delaval?
Usually not in advance. Northern Powergrid, the network operator for Seaton Delaval, 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 Seaton Delaval?
It is exported. With typical use and no battery, about 5,213 kWh of the 6,150 kWh a 12-panel system makes in Seaton Delaval goes to the grid, around £626 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 Seaton Delaval?
Yes, at a lower level. PVGIS gives Seaton Delaval 28.9 kWh per kWp in December and 33 in January, so a 12-panel system makes about 180 kWh and 210 kWh in those months, against 790 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Seaton Delaval 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 Seaton Delaval |
|---|---|---|
| Seaton Delaval | 967 | this town |
| Killingworth | 952 | −15 kWh |
| Whitley Bay | 973 | +6 kWh |
| Cramlington | 952 | −15 kWh |
| Blyth | 980 | +13 kWh |
| Longbenton | 952 | −15 kWh |
| Tynemouth | 973 | +6 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.

Do solar panels need direct sunlight? Not really, and here is why
No. Solar cells respond to light hitting them, not to a clear line of sight to the sun.
