How Erskine compares
Small towns rarely get published solar figures, so here are the numbers for Erskine. It is one of 11 Renfrewshire towns we track, and it ranks joint 1st of 11 for solar yield, a town of 16,363 people in the House of Commons Library settlement data. PVGIS gives its roofs 861 kWh per kWp a year, 2.36 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £792 of year one benefit, £247 of it from your own generation and £545 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Erskine'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.
Any planning application in Erskine sits with Renfrewshire, and its official House of Commons Library settlement class is 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 Erskine connection
SP Energy Networks owns and runs the local electricity network in Erskine, as part of its South and Central Scotland licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SP Energy Networks is notified within 28 days of switch-on rather than asked beforehand.
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.

Adding a heat pump or an EV charger in Erskine
A heat pump in Erskine
Heating demand peaks when solar is weakest. In Erskine, a 12-panel system makes about 110 kWh in December and 140 kWh in January, a fraction of its 770 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 Erskine
Erskine's May output, about 770 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.
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.

Common questions about solar in Erskine
How much electricity do solar panels make in Erskine?
About 5,480 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Erskine: 861 kWh per kWp, or 2.36 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
Is solar more expensive in Erskine?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Erskine, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,480 kWh a year here, which is what drives payback.
Which DNO covers Erskine, and what does it need from me?
SP Energy Networks covers Erskine. 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 could I earn from exporting in Erskine?
On the 12p export scenario, a 12-panel system in Erskine sends about 4,539 kWh a year to the grid, worth around £545. The export rates table compares what each supplier pays.
How much solar does Erskine get in December?
December is the low point: about 110 kWh from a 12-panel system in Erskine, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 720 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Erskine compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Erskine.
| Town | kWh per kWp a year | vs Erskine |
|---|---|---|
| Erskine | 861 | this town |
| Clydebank | 859 | −2 kWh |
| Bishopton | 857 | −4 kWh |
| Renfrew | 860 | −1 kWh |
| Linwood | 851 | −10 kWh |
| Paisley | 858 | −3 kWh |
| Dumbarton | 856 | −5 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.
