Against Great Britain as a whole: Forfar makes 943 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Forfar is 2% above it.
How Forfar compares
Small towns rarely get published solar figures, so here are the numbers for Forfar. It is one of 7 Angus towns we track, and it ranks 1st of 7 for solar yield, a town of 13,644 people in the House of Commons Library settlement data. PVGIS gives its roofs 943 kWh per kWp a year, 2.58 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £854 of year one benefit, £247 of it from your own generation and £607 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Forfar's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Forfar sits within Angus, its local planning authority, and the House of Commons Library classes it as a 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.

Connecting solar to the Forfar network
On NESO's licence-area map, Forfar is in North Scotland, which Scottish and Southern Electricity Networks (SSEN) operates. That makes SSEN the network operator for any system fitted here.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SSEN within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Heat pumps and EV charging in Forfar
A heat pump in Forfar
Solar and a heat pump pull in opposite directions through the year: Forfar's roofs make 830 kWh from November to February on a 12-panel system, and 3,020 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 Forfar
From April to September, 71% of a Forfar roof's yearly output arrives, peaking at about 820 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.

Solar in Forfar: your questions answered
What could a roof in Forfar generate?
PVGIS puts a roof in Forfar at 943 kWh per kWp a year, 2.58 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,000 kWh a year, most of it between April and September.
What would 12 solar panels cost in Forfar?
£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 Forfar differs is output: about 6,000 kWh a year from that system.
Do I need permission from the DNO for solar in Forfar?
Usually not in advance. SSEN, the network operator for Forfar, 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 would export pay on a system in Forfar?
It is exported. With typical use and no battery, about 5,061 kWh of the 6,000 kWh a 12-panel system makes in Forfar goes to the grid, around £607 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 Forfar?
Yes, at a lower level. PVGIS gives Forfar 20.4 kWh per kWp in December and 25.9 in January, so a 12-panel system makes about 130 kWh and 160 kWh in those months, against 820 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Forfar compares with its neighbours
How the towns nearest Forfar compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Forfar |

| Forfar | 943 | this town |
| Monifieth | 909 | −34 kWh |
| Carnoustie | 921 | −22 kWh |
| Broughty Ferry | 917 | −26 kWh |
| Arbroath | 940 | −3 kWh |
| Dundee | 935 | −8 kWh |
| Montrose | 923 | −20 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.
