Against Great Britain as a whole: Paisley makes 858 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Paisley is 7% below it.
How Paisley compares
Paisley is one of 11 Renfrewshire towns we track, and it ranks 4th of 11 for solar yield. The House of Commons Library settlement data classes it as a large town of 77,805 people. At 858 kWh per kWp a year, a typical 12 panel system here pays for itself in around 8.1 years on the 12p scenario: £789 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Paisley'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.
Planning applications here go through Renfrewshire; nationally, the House of Commons Library classes Paisley as a large 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 Paisley's own coordinates (55.84509, -4.42841), 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.
The network operator for Paisley
SP Energy Networks owns and runs the local electricity network in Paisley, 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.
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.

Adding a heat pump or an EV charger in Paisley
A heat pump in Paisley
In December, the darkest month here, 12 panels in Paisley make about 120 kWh. That is when a heat pump runs hardest, so its running cost in Paisley 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 Paisley
Summer is where a car earns its place. In May, 12 panels in Paisley make about 760 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).

Paisley solar questions
How much energy would 12 solar panels make in Paisley?
Paisley averages 2.35 peak sun hours a day, which PVGIS turns into 858 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,460 kWh, 72% of it between April and September.
What does a typical solar system cost in Paisley?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Paisley, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,460 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Paisley, 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 happens to the solar I do not use in Paisley?
Around £542 a year at 12p per kWh, for the roughly 4,520 kWh a 12-panel system in Paisley exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Paisley in the winter months?
December is the weakest month in Paisley: about 120 kWh from 12 panels, against 760 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Paisley compares with its neighbours
How the towns nearest Paisley compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Paisley |
|---|---|---|
| Paisley | 858 | this town |
| Renfrew | 860 | +2 kWh |
| Linwood | 851 | −7 kWh |
| Johnstone | 851 | −7 kWh |
| Barrhead | 861 | +3 kWh |
| Clydebank | 859 | +1 kWh |
| Erskine | 861 | +3 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.
