How Kilmarnock compares
Among the places we publish figures for, Kilmarnock is one of 11 Ayrshire towns we track, and it ranks 6th of 11 for solar yield. It is a medium town in the House of Commons Library classification, with 46,574 residents, and its roofs see 2.43 peak sun hours a day across the year. That drives the standard 12 panel model to 5,648 kWh of generation, of which around 4,711 kWh is exported at 12p for £565 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Kilmarnock'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.
Planning applications here go through East Ayrshire; nationally, the House of Commons Library classes Kilmarnock as a medium 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 Kilmarnock
Kilmarnock 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.
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.

Heat pumps and EV charging in Kilmarnock
A heat pump in Kilmarnock
In December, the darkest month here, 12 panels in Kilmarnock make about 120 kWh. That is when a heat pump runs hardest, so its running cost in Kilmarnock 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 Kilmarnock
Summer is where a car earns its place. In May, 12 panels in Kilmarnock 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.
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).

Kilmarnock solar questions
How much electricity do solar panels make in Kilmarnock?
About 5,650 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Kilmarnock: 888 kWh per kWp, or 2.43 peak sun hours a day on average. May is the strongest month, at about 800 kWh.
What does a typical solar system cost in Kilmarnock?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Kilmarnock, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,650 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Kilmarnock, and what does it need from me?
SP Energy Networks covers Kilmarnock. 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 happens to the solar I do not use in Kilmarnock?
Around £565 a year at 12p per kWh, for the roughly 4,711 kWh a 12-panel system in Kilmarnock exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Kilmarnock get in December?
December is the low point: about 120 kWh from a 12-panel system in Kilmarnock, on PVGIS data, rising to 800 kWh in May. From November to February the same system makes about 750 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Kilmarnock 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 Kilmarnock |
|---|---|---|
| Kilmarnock | 888 | this town |
| Irvine | 902 | +14 kWh |
| Troon | 906 | +18 kWh |
| Kilwinning | 912 | +24 kWh |
| Prestwick | 900 | +12 kWh |
| Stevenston | 886 | −2 kWh |
| Saltcoats | 885 | −3 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.
