Against Great Britain as a whole: Tavistock makes 987 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Tavistock is 7% above it.
How Tavistock compares
Small towns rarely get published solar figures, so here are the numbers for Tavistock. It is one of 23 Devon towns we track, and it ranks 22nd of 23 for solar yield, a town of 13,598 people in the House of Commons Library settlement data. PVGIS gives its roofs 987 kWh per kWp a year, 2.71 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £888 of year one benefit, £247 of it from your own generation and £641 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Tavistock'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.
Tavistock 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.

Connecting solar to the Tavistock network
On NESO's licence-area map, Tavistock is in South West England, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
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.

Heat pumps and EV charging in Tavistock
A heat pump in Tavistock
Solar and a heat pump pull in opposite directions through the year: Tavistock's roofs make 1,070 kWh from November to February on a 12-panel system, and 2,930 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Tavistock
A 12-panel roof in Tavistock makes about 770 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 Tavistock: your questions answered
What could a roof in Tavistock generate?
PVGIS puts a roof in Tavistock at 987 kWh per kWp a year, 2.71 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,280 kWh a year, most of it between April and September.
How much are solar panels in Tavistock?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Tavistock before a battery. What Tavistock changes is the return, about 6,280 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Tavistock?
Usually not in advance. NGED, the network operator for Tavistock, 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 Tavistock?
With typical use and no battery, a 12-panel system in Tavistock exports about 5,341 kWh a year. At 12p per kWh that is roughly £641; 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 Tavistock?
Yes, at a lower level. PVGIS gives Tavistock 32.1 kWh per kWp in December and 37.4 in January, so a 12-panel system makes about 200 kWh and 240 kWh in those months, against 770 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Tavistock 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 Tavistock |
|---|---|---|
| Tavistock | 987 | this town |
| Saltash | 1,065 | +78 kWh |
| Plymouth | 1,097 | +110 kWh |
| Launceston | 995 | +8 kWh |
| Ivybridge | 1,109 | +122 kWh |
| Okehampton | 976 | −11 kWh |
| Liskeard | 1,042 | +55 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.
