How Stranraer compares
Small towns rarely get published solar figures, so here are the numbers for Stranraer. It is the only Wigtownshire town we track so far, with county rankings to follow as its neighbours land, a town of 9,642 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,011 kWh per kWp a year, 2.77 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £906 of year one benefit, £247 of it from your own generation and £659 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Stranraer'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.
Stranraer 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 Stranraer network
Stranraer 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 Stranraer
A heat pump in Stranraer
Solar and a heat pump pull in opposite directions through the year: Stranraer's roofs make 880 kWh from November to February on a 12-panel system, and 3,280 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 Stranraer
A 12-panel roof in Stranraer makes about 880 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.

Stranraer solar questions
What could a roof in Stranraer generate?
PVGIS puts a roof in Stranraer at 1,011 kWh per kWp a year, 2.77 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,430 kWh a year, most of it between April and September.
How much are solar panels in Stranraer?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Stranraer before a battery. What Stranraer changes is the return, about 6,430 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Stranraer?
Usually not in advance. SP Energy Networks, the network operator for Stranraer, 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 Stranraer?
With typical use and no battery, a 12-panel system in Stranraer exports about 5,493 kWh a year. At 12p per kWh that is roughly £659; 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 Stranraer?
Yes, at a lower level. PVGIS gives Stranraer 23.6 kWh per kWp in December and 27.6 in January, so a 12-panel system makes about 150 kWh and 180 kWh in those months, against 880 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Stranraer compares with its neighbours
How the towns nearest Stranraer compare on the same PVGIS settings, closest first.

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.
