How Seaton compares
Small towns rarely get published solar figures, so here are the numbers for Seaton. It is one of 23 Devon towns we track, and it ranks 5th of 23 for solar yield, a town of 7,546 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,084 kWh per kWp a year, 2.97 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £962 of year one benefit, £247 of it from your own generation and £715 from export at 12p.
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 Seaton's own yield.
East Devon is the planning authority covering Seaton, which the House of Commons Library classes 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.

Who runs the grid in Seaton
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Seaton, as part of its South West England licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Beyond the panels: heating and car charging in Seaton
A heat pump in Seaton
A heat pump does most of its work from November to February. Over those four months, 12 panels in Seaton make about 1,120 kWh, against 3,300 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more 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 Seaton
A 12-panel roof in Seaton makes about 850 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.
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).

Solar in Seaton: your questions answered
What does a solar panel system produce in Seaton?
Each kWp of panels in Seaton makes 1,084 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,890 kWh, from about 220 kWh in December up to 850 kWh in July.
What would 12 solar panels cost in Seaton?
£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 differs is output: about 6,890 kWh a year from that system.
Would a system in Seaton need approval from the network operator?
Seaton is on National Grid Electricity Distribution's network (South West England licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Seaton?
It is exported. With typical use and no battery, about 5,958 kWh of the 6,890 kWh a 12-panel system makes in Seaton goes to the grid, around £715 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Seaton in winter?
It works, but the year is lopsided. 69% of a Seaton roof's output lands between April and September; the four months from November to February give about 1,120 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Seaton 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 |
|---|---|---|
| Seaton | 1,084 | this town |
| Sidmouth | 1,080 | −4 kWh |
| Honiton | 1,060 | −24 kWh |
| Chard | 1,050 | −34 kWh |
| Bridport | 1,105 | +21 kWh |
| Exmouth | 1,062 | −22 kWh |
| Cullompton | 1,026 | −58 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
