How Okehampton compares
Small towns rarely get published solar figures, so here are the numbers for Okehampton. It is one of 23 Devon towns we track, and it ranks 23rd of 23 for solar yield, a town of 9,872 people in the House of Commons Library settlement data. PVGIS gives its roofs 976 kWh per kWp a year, 2.67 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £879 of year one benefit, £247 of it from your own generation and £632 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Okehampton'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.
Okehampton sits within West Devon, its local planning authority, and the House of Commons Library classes it 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.

Generation is modelled from PVGIS satellite data for Okehampton's own coordinates (50.74127, -3.99446), 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.
Connecting solar to the Okehampton network
Okehampton 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.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
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 Okehampton
A heat pump in Okehampton
Solar and a heat pump pull in opposite directions through the year: Okehampton's roofs make 1,000 kWh from November to February on a 12-panel system, and 2,950 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Okehampton
A 12-panel roof in Okehampton makes about 780 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.
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 Okehampton: your questions answered
What could a roof in Okehampton generate?
PVGIS puts a roof in Okehampton at 976 kWh per kWp a year, 2.67 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,210 kWh a year, most of it between April and September.
How much are solar panels in Okehampton?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Okehampton before a battery. What Okehampton changes is the return, about 6,210 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Okehampton?
Usually not in advance. NGED, the network operator for Okehampton, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much can I earn from exporting solar in Okehampton?
With typical use and no battery, a 12-panel system in Okehampton exports about 5,271 kWh a year. At 12p per kWh that is roughly £632; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Okehampton?
Yes, at a lower level. PVGIS gives Okehampton 30.4 kWh per kWp in December and 34.5 in January, so a 12-panel system makes about 190 kWh and 220 kWh in those months, against 780 kWh in May. Winter output mostly covers daytime use rather than exporting.
