Against Great Britain as a whole: Kilwinning makes 912 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Kilwinning is 1% below it.
How Kilwinning compares
Small towns rarely get published solar figures, so here are the numbers for Kilwinning. It is one of 11 Ayrshire towns we track, and it ranks 1st of 11 for solar yield, a town of 16,136 people in the House of Commons Library settlement data. PVGIS gives its roofs 912 kWh per kWp a year, 2.50 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £831 of year one benefit, £247 of it from your own generation and £584 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Kilwinning'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.
Kilwinning sits within North Ayrshire, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Kilwinning network
Kilwinning 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.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SP Energy Networks only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. 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 Kilwinning
A heat pump in Kilwinning
Solar and a heat pump pull in opposite directions through the year: Kilwinning's roofs make 760 kWh from November to February on a 12-panel system, and 3,010 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
Scottish homes apply through Home Energy Scotland rather than the Boiler Upgrade Scheme: up to £7,500 in grant for a heat pump, up to £7,500 more as an optional interest-free loan, and a £1,500 uplift for rural and island homes (checked 28 September 2026).
Charging an EV in Kilwinning
From April to September, 73% of a Kilwinning roof's yearly output arrives, peaking at about 820 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Kilwinning solar questions
What could a roof in Kilwinning generate?
PVGIS puts a roof in Kilwinning at 912 kWh per kWp a year, 2.50 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,800 kWh a year, most of it between April and September.
What would 12 solar panels cost in Kilwinning?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Kilwinning differs is output: about 5,800 kWh a year from that system.
Do I need permission from the DNO for solar in Kilwinning?
Usually not in advance. SP Energy Networks, the network operator for Kilwinning, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval 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. "See our DNO explainer.
How much would export pay on a system in Kilwinning?
It is exported. With typical use and no battery, about 4,864 kWh of the 5,800 kWh a 12-panel system makes in Kilwinning goes to the grid, around £584 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Kilwinning?
Yes, at a lower level. PVGIS gives Kilwinning 19.4 kWh per kWp in December and 23 in January, so a 12-panel system makes about 120 kWh and 150 kWh in those months, against 820 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Kilwinning 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 Kilwinning |
|---|---|---|
| Kilwinning | 912 | this town |
| Stevenston | 886 | −26 kWh |
| Irvine | 902 | −10 kWh |
| Saltcoats | 885 | −27 kWh |
| Ardrossan | 885 | −27 kWh |
| Troon | 906 | −6 kWh |
| Kilmarnock | 888 | −24 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.
