How Tiverton compares
Small towns rarely get published solar figures, so here are the numbers for Tiverton. It is one of 23 Devon towns we track, and it ranks 21st of 23 for solar yield, a town of 19,853 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,017 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £911 of year one benefit, £247 of it from your own generation and £664 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Tiverton'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.
Planning applications here go through Mid Devon; nationally, the House of Commons Library classes Tiverton 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.

NGED and your Tiverton connection
The distribution network operator (DNO) for Tiverton is National Grid Electricity Distribution (NGED), which runs the South West England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, NGED only has to be told within 28 days after the system is commissioned.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Tiverton
A heat pump in Tiverton
In December, the darkest month here, 12 panels in Tiverton make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Tiverton comes down to the tariff and the flow temperature rather 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 Tiverton
Summer is where a car earns its place. In May, 12 panels in Tiverton make about 790 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Solar in Tiverton: your questions answered
How much electricity do solar panels make in Tiverton?
About 6,470 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Tiverton: 1,017 kWh per kWp, or 2.79 peak sun hours a day on average. May is the strongest month, at about 790 kWh.
What does a typical solar system cost in Tiverton?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Tiverton, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,470 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Tiverton, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Tiverton. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What happens to the solar I do not use in Tiverton?
Around £664 a year at 12p per kWh, for the roughly 5,531 kWh a 12-panel system in Tiverton exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Tiverton get in December?
December is the low point: about 220 kWh from a 12-panel system in Tiverton, on PVGIS data, rising to 790 kWh in May. From November to February the same system makes about 1,110 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Tiverton 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 Tiverton |
|---|---|---|
| Tiverton | 1,017 | this town |
| Cullompton | 1,026 | +9 kWh |
| Crediton | 1,020 | +3 kWh |
| Wellington | 1,008 | −9 kWh |
| Exeter | 1,060 | +43 kWh |
| Honiton | 1,060 | +43 kWh |
| Taunton | 1,026 | +9 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.
