How Largs compares
Small towns rarely get published solar figures, so here are the numbers for Largs. It is one of 11 Ayrshire towns we track, and it ranks 10th of 11 for solar yield, a town of 10,693 people in the House of Commons Library settlement data. PVGIS gives its roofs 881 kWh per kWp a year, 2.41 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £807 of year one benefit, £247 of it from your own generation and £560 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Largs' own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Planning applications here go through North Ayrshire; nationally, the House of Commons Library classes Largs 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.

The network operator for Largs
Largs sits in SP Energy Networks' South and Central Scotland licence area, so SP Energy Networks is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SP Energy Networks within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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.

Adding a heat pump or an EV charger in Largs
A heat pump in Largs
Heating demand peaks when solar is weakest. In Largs, a 12-panel system makes about 110 kWh in December and 130 kWh in January, a fraction of its 800 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Largs
Summer is where a car earns its place. In May, 12 panels in Largs make about 800 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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 Largs
How much energy would 12 solar panels make in Largs?
Largs averages 2.41 peak sun hours a day, which PVGIS turns into 881 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,600 kWh, 73% of it between April and September.
What does a typical solar system cost in Largs?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Largs, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,600 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Largs, and do I need a G99 application?
The operator is SP Energy Networks. 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. 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Largs?
Around £560 a year at 12p per kWh, for the roughly 4,666 kWh a 12-panel system in Largs exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Largs in the winter months?
December is the weakest month in Largs: about 110 kWh from 12 panels, against 800 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Largs compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Largs.
| Town | kWh per kWp a year | vs Largs |
|---|---|---|
| Largs | 881 | this town |
| Ardrossan | 885 | +4 kWh |
| Stevenston | 886 | +5 kWh |
| Saltcoats | 885 | +4 kWh |
| Greenock | 820 | −61 kWh |
| Gourock | 820 | −61 kWh |
| Kilwinning | 912 | +31 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
