How Larkhall compares
Small towns rarely get published solar figures, so here are the numbers for Larkhall. It is one of 18 Lanarkshire towns we track, and it ranks 4th of 18 for solar yield, a town of 15,210 people in the House of Commons Library settlement data. PVGIS gives its roofs 864 kWh per kWp a year, 2.37 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £794 of year one benefit, £247 of it from your own generation and £547 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Larkhall'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.
Any planning application in Larkhall sits with South Lanarkshire, and its official House of Commons Library settlement class is 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 Larkhall's own coordinates (55.73747, -3.9724), 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.
The network operator for Larkhall
Larkhall is served by SP Energy Networks: the town's centre falls inside its South and Central Scotland licence area on NESO's boundary map.
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: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
Above that, G99 means applying before the work is booked. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.

Heat pumps and EV charging in Larkhall
A heat pump in Larkhall
In December, the darkest month here, 12 panels in Larkhall make about 120 kWh. That is when a heat pump runs hardest, so its running cost in Larkhall comes down to the tariff and the flow temperature rather than the roof.
In Scotland, Home Energy Scotland offers a grant of up to £7,500 towards a heat pump, an optional interest-free loan of up to £7,500 on top, and £1,500 more for rural and island homes (Home Energy Scotland, checked 28 September 2026).
Charging an EV in Larkhall
Larkhall's May output, about 770 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.

Larkhall solar questions
How much electricity do solar panels make in Larkhall?
About 5,500 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Larkhall: 864 kWh per kWp, or 2.37 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
Is solar more expensive in Larkhall?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Larkhall, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,500 kWh a year here, which is what drives payback.
Which DNO covers Larkhall, and what does it need from me?
SP Energy Networks covers Larkhall. A home system of up to 3.68kW per phase is notified to SP Energy Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.
What could I earn from exporting in Larkhall?
On the 12p export scenario, a 12-panel system in Larkhall sends about 4,558 kWh a year to the grid, worth around £547. The export rates table compares what each supplier pays.
How much solar does Larkhall get in December?
December is the low point: about 120 kWh from a 12-panel system in Larkhall, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 760 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Larkhall 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 Larkhall |
|---|---|---|
| Larkhall | 864 | this town |
| Wishaw | 861 | −3 kWh |
| Hamilton | 871 | +7 kWh |
| Motherwell | 870 | +6 kWh |
| Carluke | 846 | −18 kWh |
| Strathaven | 804 | −60 kWh |
| Blantyre | 866 | +2 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.
