Against Great Britain as a whole: Annan makes 929 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Annan is level with it.
How Annan compares
Small towns rarely get published solar figures, so here are the numbers for Annan. It is one of 2 Dumfriesshire towns we track, and it ranks 1st of 2 for solar yield, a town of 8,776 people in the House of Commons Library settlement data. PVGIS gives its roofs 929 kWh per kWp a year, 2.54 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £844 of year one benefit, £247 of it from your own generation and £597 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Annan'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.
Annan sits within Dumfries and Galloway, 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 Annan network
Annan sits in SP Energy Networks' South and Central Scotland licence area, so SP Energy Networks is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SP Energy Networks within 28 days of commissioning, with no prior approval.
Anything bigger is a G99 case and is applied for 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.

Adding a heat pump or an EV charger in Annan
A heat pump in Annan
Solar and a heat pump pull in opposite directions through the year: Annan's roofs make 870 kWh from November to February on a 12-panel system, and 2,970 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 Annan
A 12-panel roof in Annan makes about 810 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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.

Annan solar questions
What could a roof in Annan generate?
PVGIS puts a roof in Annan at 929 kWh per kWp a year, 2.54 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,910 kWh a year, most of it between April and September.
How much are solar panels in Annan?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Annan before a battery. What Annan changes is the return, about 5,910 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Annan?
Usually not in advance. SP Energy Networks, the network operator for Annan, 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 can I earn from exporting solar in Annan?
With typical use and no battery, a 12-panel system in Annan exports about 4,972 kWh a year. At 12p per kWh that is roughly £597; 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 Annan?
Yes, at a lower level. PVGIS gives Annan 23.9 kWh per kWp in December and 27.5 in January, so a 12-panel system makes about 150 kWh and 170 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Annan compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Annan |
|---|---|---|
| Annan | 929 | this town |
| Carlisle | 915 | −14 kWh |
| Dumfries | 923 | −6 kWh |
| Maryport | 956 | +27 kWh |
| Cockermouth | 868 | −61 kWh |
| Workington | 950 | +21 kWh |
| Penrith | 897 | −32 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
