Against Great Britain as a whole: Launceston makes 995 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Launceston is 8% above it.
How Launceston compares
Small towns rarely get published solar figures, so here are the numbers for Launceston. It is one of 14 Cornwall towns we track, and it ranks 14th of 14 for solar yield, a town of 8,234 people in the House of Commons Library settlement data. PVGIS gives its roofs 995 kWh per kWp a year, 2.73 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £894 of year one benefit, £247 of it from your own generation and £647 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Launceston'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 Launceston, 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 Launceston's own coordinates (50.63472, -4.36523), 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 Launceston
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Launceston, as part of its South West England licence area.
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 Launceston
A heat pump in Launceston
A heat pump does most of its work from November to February. Over those four months, 12 panels in Launceston make about 1,040 kWh, against 2,990 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Launceston
A 12-panel roof in Launceston 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar in Launceston: your questions answered
What does a solar panel system produce in Launceston?
Each kWp of panels in Launceston makes 995 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,330 kWh, from about 200 kWh in December up to 780 kWh in May.
How much are solar panels in Launceston?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Launceston before a battery. What Launceston changes is the return, about 6,330 kWh a year from that system, and your design call prices your actual roof.
Would a system in Launceston need approval from the network operator?
Launceston 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 Launceston?
With typical use and no battery, a 12-panel system in Launceston exports about 5,392 kWh a year. At 12p per kWh that is roughly £647; 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 Launceston in winter?
It works, but the year is lopsided. 68% of a Launceston roof's output lands between April and September; the four months from November to February give about 1,040 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Launceston compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Launceston.

| Tavistock | 987 | −8 kWh |
| Liskeard | 1,042 | +47 kWh |
| Saltash | 1,065 | +70 kWh |
| Okehampton | 976 | −19 kWh |
| Bodmin | 1,039 | +44 kWh |
| Plymouth | 1,097 | +102 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.
