How Bonhill and Renton compares
Small towns rarely get published solar figures, so here are the numbers for Bonhill and Renton. It is one of 7 Dunbartonshire towns we track, and it ranks 5th of 7 for solar yield, a town of 8,419 people in the House of Commons Library settlement data. PVGIS gives its roofs 846 kWh per kWp a year, 2.32 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £780 of year one benefit, £247 of it from your own generation and £533 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Bonhill and Renton's own yield.
Any planning application in Bonhill and Renton sits with West Dunbartonshire, 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.

The network operator for Bonhill and Renton
SP Energy Networks owns and runs the local electricity network in Bonhill and Renton, 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.
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.

Beyond the panels: heating and car charging in Bonhill and Renton
A heat pump in Bonhill and Renton
Heating demand peaks when solar is weakest. In Bonhill and Renton, a 12-panel system makes about 110 kWh in December and 130 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 Bonhill and Renton
Summer is where a car earns its place. In May, 12 panels in Bonhill and Renton make about 770 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.
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.

Solar in Bonhill and Renton: your questions answered
How much electricity do solar panels make in Bonhill and Renton?
About 5,380 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Bonhill and Renton: 846 kWh per kWp, or 2.32 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
What does a typical solar system cost in Bonhill and Renton?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Bonhill and Renton, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,380 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Bonhill and Renton, and what does it need from me?
SP Energy Networks covers Bonhill and Renton. 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 happens to the solar I do not use in Bonhill and Renton?
Around £533 a year at 12p per kWh, for the roughly 4,444 kWh a 12-panel system in Bonhill and Renton exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Bonhill and Renton get in December?
December is the low point: about 110 kWh from a 12-panel system in Bonhill and Renton, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 690 kWh in total, which is why a battery charged off-peak does more of the work in winter.
