How Teignmouth compares
Small towns rarely get published solar figures, so here are the numbers for Teignmouth. It is one of 23 Devon towns we track, and it ranks 16th of 23 for solar yield, a town of 15,387 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,032 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £922 of year one benefit, £247 of it from your own generation and £675 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 Teignmouth's own yield.
Teignbridge is the planning authority covering Teignmouth, 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 Teignmouth
Teignmouth is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its South West 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 NGED within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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 Teignmouth
A heat pump in Teignmouth
A heat pump does most of its work from November to February. Over those four months, 12 panels in Teignmouth make about 1,070 kWh, against 3,140 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 Teignmouth
A 12-panel roof in Teignmouth makes about 820 kWh in May. 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).

Common questions about solar in Teignmouth
What does a solar panel system produce in Teignmouth?
Each kWp of panels in Teignmouth makes 1,032 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,560 kWh, from about 220 kWh in December up to 820 kWh in May.
How much are solar panels in Teignmouth?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Teignmouth before a battery. What Teignmouth changes is the return, about 6,560 kWh a year from that system, and your design call prices your actual roof.
Would a system in Teignmouth need approval from the network operator?
Teignmouth 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 can I earn from exporting solar in Teignmouth?
With typical use and no battery, a 12-panel system in Teignmouth exports about 5,627 kWh a year. At 12p per kWh that is roughly £675; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Teignmouth in winter?
It works, but the year is lopsided. 69% of a Teignmouth roof's output lands between April and September; the four months from November to February give about 1,070 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Teignmouth 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 Teignmouth |
|---|---|---|
| Teignmouth | 1,032 | this town |
| Dawlish | 1,044 | +12 kWh |
| Kingsteignton | 1,063 | +31 kWh |
| Newton Abbot | 1,051 | +19 kWh |
| Torquay | 1,058 | +26 kWh |
| Exmouth | 1,062 | +30 kWh |
| Paignton | 1,085 | +53 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.
