How Sidmouth compares
Small towns rarely get published solar figures, so here are the numbers for Sidmouth. It is one of 23 Devon towns we track, and it ranks 6th of 23 for solar yield, a town of 13,397 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,080 kWh per kWp a year, 2.96 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £959 of year one benefit, £247 of it from your own generation and £712 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Sidmouth'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 Sidmouth 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.

The network operator for Sidmouth
Sidmouth sits in National Grid Electricity Distribution's South West England licence area, so NGED is the network operator (DNO) any solar panels or battery here are registered with.
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.

Adding a heat pump or an EV charger in Sidmouth
A heat pump in Sidmouth
Heating demand peaks when solar is weakest. In Sidmouth, a 12-panel system makes about 230 kWh in December and 250 kWh in January, a fraction of its 850 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Sidmouth
Summer is where a car earns its place. In July, 12 panels in Sidmouth make about 850 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.

Common questions about solar in Sidmouth
How much energy would 12 solar panels make in Sidmouth?
Sidmouth averages 2.96 peak sun hours a day, which PVGIS turns into 1,080 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,870 kWh, 69% of it between April and September.
What does a typical solar system cost in Sidmouth?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Sidmouth, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,870 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Sidmouth, 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 Sidmouth?
Around £712 a year at 12p per kWh, for the roughly 5,932 kWh a 12-panel system in Sidmouth 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 Sidmouth in the winter months?
December is the weakest month in Sidmouth: about 230 kWh from 12 panels, against 850 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
