How Alloa compares
Small towns rarely get published solar figures, so here are the numbers for Alloa. It is one of 2 Clackmannanshire towns we track, and it ranks 2nd of 2 for solar yield, a town of 20,452 people in the House of Commons Library settlement data. PVGIS gives its roofs 878 kWh per kWp a year, 2.40 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £805 of year one benefit, £247 of it from your own generation and £558 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Alloa'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.
Any planning application in Alloa sits with Clackmannanshire, and its official House of Commons Library settlement class is 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.

The network operator for Alloa
SP Energy Networks owns and runs the local electricity network in Alloa, as part of its South and Central Scotland licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
Above that, G99 means applying before the work is booked. 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 Alloa
A heat pump in Alloa
In December, the darkest month here, 12 panels in Alloa make about 130 kWh. That is when a heat pump runs hardest, so its running cost in Alloa comes down to the tariff and the flow temperature rather than the roof.
In Scotland, Home Energy Scotland offers a grant of up to £7,500 towards a heat pump, an optional interest-free loan of up to £7,500 on top, and £1,500 more for rural and island homes (Home Energy Scotland, checked 28 September 2026).
Charging an EV in Alloa
Alloa's May output, about 780 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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).

Common questions about solar in Alloa
How much electricity do solar panels make in Alloa?
About 5,580 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Alloa: 878 kWh per kWp, or 2.40 peak sun hours a day on average. May is the strongest month, at about 780 kWh.
Is solar more expensive in Alloa?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Alloa, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,580 kWh a year here, which is what drives payback.
Which DNO covers Alloa, and what does it need from me?
SP Energy Networks covers Alloa. A home system of up to 3.68kW per phase is notified to SP Energy Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Alloa?
On the 12p export scenario, a 12-panel system in Alloa sends about 4,647 kWh a year to the grid, worth around £558. The export rates table compares what each supplier pays.
How much solar does Alloa get in December?
December is the low point: about 130 kWh from a 12-panel system in Alloa, on PVGIS data, rising to 780 kWh in May. From November to February the same system makes about 770 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Alloa compares with its neighbours
How the towns nearest Alloa compare on the same PVGIS settings, closest first.
