How Liskeard compares
Small towns rarely get published solar figures, so here are the numbers for Liskeard. It is one of 14 Cornwall towns we track, and it ranks 10th of 14 for solar yield, a town of 11,703 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,042 kWh per kWp a year, 2.86 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £930 of year one benefit, £247 of it from your own generation and £683 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 Liskeard's own yield.
Planning applications here go through Cornwall; nationally, the House of Commons Library classes Liskeard 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.

NGED and your Liskeard connection
On NESO's licence-area map, Liskeard is in South West England, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
Above that, G99 means applying before the work is booked. 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 Liskeard
A heat pump in Liskeard
In December, the darkest month here, 12 panels in Liskeard make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Liskeard comes down to the tariff and the flow temperature rather 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 Liskeard
Liskeard's May output, about 810 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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.

Common questions about solar in Liskeard
How much energy would 12 solar panels make in Liskeard?
Liskeard averages 2.86 peak sun hours a day, which PVGIS turns into 1,042 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,630 kWh, 68% of it between April and September.
Is solar more expensive in Liskeard?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Liskeard, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,630 kWh a year here, which is what drives payback.
Who is the network operator in Liskeard, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What could I earn from exporting in Liskeard?
On the 12p export scenario, a 12-panel system in Liskeard sends about 5,690 kWh a year to the grid, worth around £683. The export rates table compares what each supplier pays.
How does solar perform in Liskeard in the winter months?
December is the weakest month in Liskeard: about 220 kWh from 12 panels, against 810 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Liskeard 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 Liskeard |
|---|---|---|
| Liskeard | 1,042 | this town |
| Saltash | 1,065 | +23 kWh |
| Bodmin | 1,039 | −3 kWh |
| Launceston | 995 | −47 kWh |
| Tavistock | 987 | −55 kWh |
| Plymouth | 1,097 | +55 kWh |
| St Austell | 1,051 | +9 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.
