Against Great Britain as a whole: Renfrewshire makes 851 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Renfrewshire is 8% below it.
How Renfrewshire compares
Renfrewshire ranks 60th of the 85 counties we track for solar yield. Self use does the heavy lifting here: of the £784 year one benefit on a typical 12 panel system, £247 comes from replacing 26.32p imports with your own generation, which is why battery sizing matters more than panel count.
These are county-level starting numbers. A town page gives the figure for its own centroid, and your design call replaces both with your roof, its shading and your bills.
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 from PVGIS v5.2 (European Commission JRC, SARAH3), retrieved August 2026 for a representative point in Renfrewshire (55.8332, -4.5292), assuming 1 kWp, 14% system loss, 35 degree pitch, due south. Import valued at 26.32p/kWh (Ofgem price cap average, Oct to Dec 2026); off-peak charging at 8.5p/kWh where used (a supplier's published off-peak rate, checked September 2026); export at the scenario you pick, from the dated tariff table. Prices are installed pricing, August 2026, standard installations; 530W LONGi panels at £1,000 per kWp. Estimates for illustration, not a quote: your free design call prices your actual roof.
Connecting solar to the Renfrewshire network
The centre of Renfrewshire sits in SP Energy Networks' South and Central Scotland licence area on NESO's boundary map, as does every town we cover there, so SP Energy Networks is the network operator (DNO) a system here is registered with.
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.
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 Renfrewshire
A heat pump in Renfrewshire
Solar and a heat pump pull in opposite directions through the year: Renfrewshire's roofs make 710 kWh from November to February on a 12-panel system, and 2,800 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 Renfrewshire
From April to September, 73% of a Renfrewshire 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.
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.

Renfrewshire solar questions
What could a roof in Renfrewshire generate?
PVGIS puts a roof in Renfrewshire at 851 kWh per kWp a year, 2.33 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,410 kWh a year, most of it between April and September.
What would 12 solar panels cost in Renfrewshire?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Renfrewshire differs is output: about 5,410 kWh a year from that system.
Do I need permission from the DNO for solar in Renfrewshire?
Usually not in advance. SP Energy Networks, the network operator for Renfrewshire, 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 would export pay on a system in Renfrewshire?
It is exported. With typical use and no battery, about 4,476 kWh of the 5,410 kWh a 12-panel system makes in Renfrewshire goes to the grid, around £537 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Renfrewshire?
Yes, at a lower level. PVGIS gives Renfrewshire 18.1 kWh per kWp in December and 20.9 in January, so a 12-panel system makes about 120 kWh and 130 kWh in those months, against 760 kWh in May. Winter output mostly covers daytime use rather than exporting.
