How Cumnock compares
Small towns rarely get published solar figures, so here are the numbers for Cumnock. It is one of 11 Ayrshire towns we track, and it ranks 11th of 11 for solar yield, a town of 8,234 people in the House of Commons Library settlement data. PVGIS gives its roofs 838 kWh per kWp a year, 2.30 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £774 of year one benefit, £247 of it from your own generation and £527 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Cumnock's 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.
East Ayrshire is the planning authority covering Cumnock, which the House of Commons Library classes 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.

Generation is modelled from PVGIS satellite data for Cumnock's own coordinates (55.45485, -4.26722), 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.
Who runs the grid in Cumnock
The distribution network operator (DNO) for Cumnock is SP Energy Networks, which runs the South and Central Scotland licence area.
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.

Adding a heat pump or an EV charger in Cumnock
A heat pump in Cumnock
A heat pump does most of its work from November to February. Over those four months, 12 panels in Cumnock make about 720 kWh, against 2,710 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Cumnock
From April to September, 72% of a Cumnock roof's yearly output arrives, peaking at about 760 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).

Common questions about solar in Cumnock
What does a solar panel system produce in Cumnock?
Each kWp of panels in Cumnock makes 838 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,330 kWh, from about 120 kWh in December up to 760 kWh in May.
How much are solar panels in Cumnock?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Cumnock before a battery. What Cumnock changes is the return, about 5,330 kWh a year from that system, and your design call prices your actual roof.
Would a system in Cumnock need approval from the network operator?
Cumnock is on SP Energy Networks' network (South and Central Scotland licence area). Systems up to 3.68kW per phase of inverter output follow G98: SP Energy Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Cumnock?
With typical use and no battery, a 12-panel system in Cumnock exports about 4,393 kWh a year. At 12p per kWh that is roughly £527; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Cumnock in winter?
It works, but the year is lopsided. 72% of a Cumnock roof's output lands between April and September; the four months from November to February give about 720 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Cumnock compares with its neighbours
How the towns nearest Cumnock compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Cumnock |
|---|---|---|
| Cumnock | 838 | this town |
| Prestwick | 900 | +62 kWh |
| Kilmarnock | 888 | +50 kWh |
| Ayr | 899 | +61 kWh |
| Troon | 906 | +68 kWh |
| Strathaven | 804 | −34 kWh |
| Irvine | 902 | +64 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.
