How Stevenston compares
Small towns rarely get published solar figures, so here are the numbers for Stevenston. It is one of 11 Ayrshire towns we track, and it ranks 7th of 11 for solar yield, a town of 8,608 people in the House of Commons Library settlement data. PVGIS gives its roofs 886 kWh per kWp a year, 2.43 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £811 of year one benefit, £247 of it from your own generation and £564 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 Stevenston's own yield.
Planning applications here go through North Ayrshire; nationally, the House of Commons Library classes Stevenston 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.

SP Energy Networks and your Stevenston connection
SP Energy Networks owns and runs the local electricity network in Stevenston, as part of its South and Central Scotland licence area.
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.

Beyond the panels: heating and car charging in Stevenston
A heat pump in Stevenston
Heating demand peaks when solar is weakest. In Stevenston, a 12-panel system makes about 120 kWh in December and 140 kWh in January, a fraction of its 810 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 Stevenston
Stevenston'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.
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).

Solar in Stevenston: your questions answered
How much energy would 12 solar panels make in Stevenston?
Stevenston averages 2.43 peak sun hours a day, which PVGIS turns into 886 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,630 kWh, 73% of it between April and September.
Is solar more expensive in Stevenston?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Stevenston, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,630 kWh a year here, which is what drives payback.
Who is the network operator in Stevenston, 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 could I earn from exporting in Stevenston?
On the 12p export scenario, a 12-panel system in Stevenston sends about 4,698 kWh a year to the grid, worth around £564. The export rates table compares what each supplier pays.
How does solar perform in Stevenston in the winter months?
December is the weakest month in Stevenston: about 120 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 Stevenston compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Stevenston.

| Ardrossan | 885 | −1 kWh |
| Kilwinning | 912 | +26 kWh |
| Irvine | 902 | +16 kWh |
| Troon | 906 | +20 kWh |
| Kilmarnock | 888 | +2 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.

Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Charging an EV from your own solar
Every surplus kWh is 3.6 to 5 miles. Whether that beats a 7p overnight rate is arithmetic.
Read the guide →Do you need to replace your radiators for a heat pump?
Some change, most do not. The room by room arithmetic that decides which.
Read the guide →Why tariff choice moves payback more than kit choice
Identical kit, five times the export income. The tariff decision worked through with August 2026 rates.
