How Honiton compares
Small towns rarely get published solar figures, so here are the numbers for Honiton. It is one of 23 Devon towns we track, and it ranks joint 10th of 23 for solar yield, a town of 12,964 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,060 kWh per kWp a year, 2.90 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £944 of year one benefit, £247 of it from your own generation and £697 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Honiton's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Any planning application in Honiton sits with East Devon, and its official House of Commons Library settlement class is 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 Honiton connection
On NESO's licence-area map, Honiton is in South West England, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
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.

Adding a heat pump or an EV charger in Honiton
A heat pump in Honiton
In December, the darkest month here, 12 panels in Honiton make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Honiton comes down to the tariff and the flow temperature rather than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Honiton
Summer is where a car earns its place. In July, 12 panels in Honiton make about 820 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.

Honiton solar questions
How much energy would 12 solar panels make in Honiton?
Honiton averages 2.90 peak sun hours a day, which PVGIS turns into 1,060 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,740 kWh, 68% of it between April and September.
What does a typical solar system cost in Honiton?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Honiton, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,740 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Honiton, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Honiton?
Around £697 a year at 12p per kWh, for the roughly 5,805 kWh a 12-panel system in Honiton exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Honiton in the winter months?
December is the weakest month in Honiton: about 240 kWh from 12 panels, against 820 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Honiton 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 Honiton |
|---|---|---|
| Honiton | 1,060 | this town |
| Sidmouth | 1,080 | +20 kWh |
| Seaton | 1,084 | +24 kWh |
| Cullompton | 1,026 | −34 kWh |
| Chard | 1,050 | −10 kWh |
| Wellington | 1,008 | −52 kWh |
| Exmouth | 1,062 | +2 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.
