How St Andrews compares
Small towns rarely get published solar figures, so here are the numbers for St Andrews. It is one of 10 Fife towns we track, and it ranks 1st of 10 for solar yield, a town of 12,066 people in the House of Commons Library settlement data. PVGIS gives its roofs 983 kWh per kWp a year, 2.69 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £885 of year one benefit, £247 of it from your own generation and £638 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 St Andrews' own yield.
St Andrews sits within Fife, 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 St Andrews network
St Andrews 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.

Beyond the panels: heating and car charging in St Andrews
A heat pump in St Andrews
Solar and a heat pump pull in opposite directions through the year: St Andrews' roofs make 880 kWh from November to February on a 12-panel system, and 3,150 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 St Andrews
A 12-panel roof in St Andrews makes about 860 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in St Andrews: your questions answered
What could a roof in St Andrews generate?
PVGIS puts a roof in St Andrews at 983 kWh per kWp a year, 2.69 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,250 kWh a year, most of it between April and September.
How much are solar panels in St Andrews?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in St Andrews before a battery. What St Andrews changes is the return, about 6,250 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in St Andrews?
Usually not in advance. SP Energy Networks, the network operator for St Andrews, 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 St Andrews?
With typical use and no battery, a 12-panel system in St Andrews exports about 5,315 kWh a year. At 12p per kWh that is roughly £638; 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 St Andrews?
Yes, at a lower level. PVGIS gives St Andrews 22.6 kWh per kWp in December and 28.5 in January, so a 12-panel system makes about 140 kWh and 180 kWh in those months, against 860 kWh in May. Winter output mostly covers daytime use rather than exporting.
How St Andrews 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 St Andrews |
|---|---|---|
| St Andrews | 983 | this town |
| Cupar | 940 | −43 kWh |
| Broughty Ferry | 917 | −66 kWh |
| Monifieth | 909 | −74 kWh |
| Dundee | 935 | −48 kWh |
| Carnoustie | 921 | −62 kWh |
| Leven | 894 | −89 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
