Against Great Britain as a whole: Dunbartonshire makes 822 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Dunbartonshire is 11% below it.
How Dunbartonshire compares
Dunbartonshire ranks joint 72nd of the 85 counties we track for solar yield, 2% below the Scotland average of our estimates. Lower light changes the strategy rather than the answer: pair the array with off peak charging at 8.5p and the model still finds £761 a year on a typical 12 panel system, most of it from cutting 26.32p imports.
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.

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 Dunbartonshire network
The centre of Dunbartonshire sits in Scottish and Southern Electricity Networks' North Scotland licence area on NESO's boundary map, so SSEN is the network operator (DNO) a system here is registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
Anything bigger is a G99 case and is applied for first. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.
Parts of Dunbartonshire are on a different network: some of its towns are served by SP Energy Networks. Each town page names its own operator, worked out from that town's own location.
Sources: NESO DNO licence areas (3 May 2024); SSEN, micro-generation connections page, checked 25 September 2026. G98 vs G99, explained.
Adding a heat pump or an EV charger in Dunbartonshire
A heat pump in Dunbartonshire
Solar and a heat pump pull in opposite directions through the year: Dunbartonshire's roofs make 660 kWh from November to February on a 12-panel system, and 2,740 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 Dunbartonshire
From April to September, 73% of a Dunbartonshire roof's yearly output arrives, peaking at about 750 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Dunbartonshire solar questions
What could a roof in Dunbartonshire generate?
PVGIS puts a roof in Dunbartonshire at 822 kWh per kWp a year, 2.25 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,230 kWh a year, most of it between April and September.
How much are solar panels in Dunbartonshire?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Dunbartonshire before a battery. What Dunbartonshire changes is the return, about 5,230 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Dunbartonshire?
Usually not in advance. SSEN, the network operator for the centre of Dunbartonshire, 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. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW. "See our DNO explainer.
How much can I earn from exporting solar in Dunbartonshire?
With typical use and no battery, a 12-panel system in Dunbartonshire exports about 4,291 kWh a year. At 12p per kWh that is roughly £515; 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 Dunbartonshire?
Yes, at a lower level. PVGIS gives Dunbartonshire 16.6 kWh per kWp in December and 18.6 in January, so a 12-panel system makes about 110 kWh and 120 kWh in those months, against 750 kWh in May. Winter output mostly covers daytime use rather than exporting.
