How Truro compares
Small towns rarely get published solar figures, so here are the numbers for Truro. It is one of 14 Cornwall towns we track, and it ranks 8th of 14 for solar yield, a town of 24,271 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,052 kWh per kWp a year, 2.88 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £937 of year one benefit, £247 of it from your own generation and £690 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Truro's own yield.
Cornwall is the planning authority covering Truro, which the House of Commons Library classes 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.

Who runs the grid in Truro
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Truro, as part of its South West England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means NGED is notified within 28 days of switch-on rather than asked beforehand.
A bigger inverter or battery output needs a G99 application in advance. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Beyond the panels: heating and car charging in Truro
A heat pump in Truro
A heat pump does most of its work from November to February. Over those four months, 12 panels in Truro make about 1,120 kWh, against 3,160 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more 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 Truro
A 12-panel roof in Truro makes about 820 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.

Common questions about solar in Truro
What does a solar panel system produce in Truro?
Each kWp of panels in Truro makes 1,052 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,690 kWh, from about 220 kWh in December up to 820 kWh in May.
What would 12 solar panels cost in Truro?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Truro differs is output: about 6,690 kWh a year from that system.
Would a system in Truro need approval from the network operator?
Truro is on National Grid Electricity Distribution's network (South West England licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Truro?
It is exported. With typical use and no battery, about 5,754 kWh of the 6,690 kWh a 12-panel system makes in Truro goes to the grid, around £690 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Truro in winter?
It works, but the year is lopsided. 68% of a Truro roof's output lands between April and September; the four months from November to February give about 1,120 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Truro 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 Truro |
|---|---|---|
| Truro | 1,052 | this town |
| Penryn | 1,062 | +10 kWh |
| Redruth | 1,038 | −14 kWh |
| Falmouth | 1,056 | +4 kWh |
| Newquay | 1,054 | +2 kWh |
| Camborne | 1,026 | −26 kWh |
| St Austell | 1,051 | −1 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.
