How Prestwick compares
Small towns rarely get published solar figures, so here are the numbers for Prestwick. It is one of 11 Ayrshire towns we track, and it ranks 4th of 11 for solar yield, a town of 14,061 people in the House of Commons Library settlement data. PVGIS gives its roofs 900 kWh per kWp a year, 2.47 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £821 of year one benefit, £247 of it from your own generation and £574 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Prestwick'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.
Prestwick sits within South 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 Prestwick network
The distribution network operator (DNO) for Prestwick 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.
Anything bigger is a G99 case and is applied for 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.

Adding a heat pump or an EV charger in Prestwick
A heat pump in Prestwick
Solar and a heat pump pull in opposite directions through the year: Prestwick's roofs make 770 kWh from November to February on a 12-panel system, and 2,920 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 Prestwick
From April to September, 72% of a Prestwick 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.
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.

Prestwick solar questions
What could a roof in Prestwick generate?
PVGIS puts a roof in Prestwick at 900 kWh per kWp a year, 2.47 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,720 kWh a year, most of it between April and September.
How much are solar panels in Prestwick?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Prestwick before a battery. What Prestwick changes is the return, about 5,720 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Prestwick?
Usually not in advance. SP Energy Networks, the network operator for Prestwick, 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 can I earn from exporting solar in Prestwick?
With typical use and no battery, a 12-panel system in Prestwick exports about 4,787 kWh a year. At 12p per kWh that is roughly £574; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Prestwick?
Yes, at a lower level. PVGIS gives Prestwick 19.5 kWh per kWp in December and 22.8 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 Prestwick 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 Prestwick |
|---|---|---|
| Prestwick | 900 | this town |
| Ayr | 899 | −1 kWh |
| Troon | 906 | +6 kWh |
| Irvine | 902 | +2 kWh |
| Kilmarnock | 888 | −12 kWh |
| Kilwinning | 912 | +12 kWh |
| Stevenston | 886 | −14 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.
