Redruth's solar year

How Redruth compares
Small towns rarely get published solar figures, so here are the numbers for Redruth. It is one of 14 Cornwall towns we track, and it ranks 12th of 14 for solar yield, a town of 16,113 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,038 kWh per kWp a year, 2.84 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £927 of year one benefit, £247 of it from your own generation and £680 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Redruth'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.
Cornwall is the planning authority covering Redruth, 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.

Generation is modelled from PVGIS satellite data for Redruth's own coordinates (50.23574, -5.22637), 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.
Who runs the grid in Redruth
On NESO's licence-area map, Redruth 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.
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.

Heat pumps and EV charging in Redruth
A heat pump in Redruth
A heat pump does most of its work from November to February. Over those four months, 12 panels in Redruth make about 1,100 kWh, against 3,140 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 Redruth
A 12-panel roof in Redruth makes about 810 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 Redruth: your questions answered
What does a solar panel system produce in Redruth?
Each kWp of panels in Redruth makes 1,038 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,600 kWh, from about 210 kWh in December up to 810 kWh in May.
How much are solar panels in Redruth?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Redruth before a battery. What Redruth changes is the return, about 6,600 kWh a year from that system, and your design call prices your actual roof.
Would a system in Redruth need approval from the network operator?
Redruth 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 can I earn from exporting solar in Redruth?
With typical use and no battery, a 12-panel system in Redruth exports about 5,665 kWh a year. At 12p per kWh that is roughly £680; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Redruth in winter?
It works, but the year is lopsided. 68% of a Redruth roof's output lands between April and September; the four months from November to February give about 1,100 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Redruth 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 Redruth |
|---|---|---|
| Redruth | 1,038 | this town |
| Camborne | 1,026 | −12 kWh |
| Penryn | 1,062 | +24 kWh |
| Truro | 1,052 | +14 kWh |
| Falmouth | 1,056 | +18 kWh |
| Hayle | 1,102 | +64 kWh |
| Helston | 1,110 | +72 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
