How Exmouth compares
Among the places we publish figures for, Exmouth is one of 23 Devon towns we track, and it ranks 9th of 23 for solar yield. It is a medium town in the House of Commons Library classification, with 36,204 residents, and its roofs see 2.91 peak sun hours a day across the year. That drives the standard 12 panel model to 6,754 kWh of generation, of which around 5,818 kWh is exported at 12p for £698 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Exmouth'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.
East Devon is the planning authority covering Exmouth, which the House of Commons Library classes 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.

Generation is modelled from PVGIS satellite data for Exmouth's own coordinates (50.62773, -3.39445), 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.
Who runs the grid in Exmouth
The distribution network operator (DNO) for Exmouth is National Grid Electricity Distribution (NGED), which runs the South West England 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.
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.

Heat pumps and EV charging in Exmouth
A heat pump in Exmouth
A heat pump does most of its work from November to February. Over those four months, 12 panels in Exmouth make about 1,140 kWh, against 3,200 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Exmouth
From April to September, 68% of a Exmouth roof's yearly output arrives, peaking at about 830 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar in Exmouth: your questions answered
What does a solar panel system produce in Exmouth?
Each kWp of panels in Exmouth makes 1,062 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,750 kWh, from about 240 kWh in December up to 830 kWh in May.
What would 12 solar panels cost in Exmouth?
£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 Exmouth differs is output: about 6,750 kWh a year from that system.
Would a system in Exmouth need approval from the network operator?
Exmouth 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 Exmouth?
It is exported. With typical use and no battery, about 5,818 kWh of the 6,750 kWh a 12-panel system makes in Exmouth goes to the grid, around £698 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 Exmouth in winter?
It works, but the year is lopsided. 68% of a Exmouth roof's output lands between April and September; the four months from November to February give about 1,140 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Exmouth compares with its neighbours
How the towns nearest Exmouth compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Exmouth |
|---|---|---|
| Exmouth | 1,062 | this town |
| Dawlish | 1,044 | −18 kWh |
| Teignmouth | 1,032 | −30 kWh |
| Sidmouth | 1,080 | +18 kWh |
| Exeter | 1,060 | −2 kWh |
| Kingsteignton | 1,063 | +1 kWh |
| Newton Abbot | 1,051 | −11 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.
