How Denny compares
Small towns rarely get published solar figures, so here are the numbers for Denny. It is one of 9 Stirlingshire towns we track, and it ranks 7th of 9 for solar yield, a town of 10,570 people in the House of Commons Library settlement data. PVGIS gives its roofs 856 kWh per kWp a year, 2.35 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £788 of year one benefit, £247 of it from your own generation and £541 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Denny'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.
Falkirk is the planning authority covering Denny, which the House of Commons Library classes 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.

Generation is modelled from PVGIS satellite data for Denny's own coordinates (56.02284, -3.90751), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Who runs the grid in Denny
Denny 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.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SP Energy Networks only has to be told within 28 days after the system is commissioned.
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.

Heat pumps and EV charging in Denny
A heat pump in Denny
A heat pump does most of its work from November to February. Over those four months, 12 panels in Denny make about 740 kWh, against 2,780 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Denny
A 12-panel roof in Denny makes about 760 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.
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.

Denny solar questions
What does a solar panel system produce in Denny?
Each kWp of panels in Denny makes 856 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,440 kWh, from about 120 kWh in December up to 760 kWh in May.
What would 12 solar panels cost in Denny?
£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 Denny differs is output: about 5,440 kWh a year from that system.
Would a system in Denny need approval from the network operator?
Denny is on SP Energy Networks' network (South and Central Scotland licence area). Systems up to 3.68kW per phase of inverter output follow G98: SP Energy Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Denny?
It is exported. With typical use and no battery, about 4,507 kWh of the 5,440 kWh a 12-panel system makes in Denny goes to the grid, around £541 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Denny in winter?
It works, but the year is lopsided. 72% of a Denny roof's output lands between April and September; the four months from November to February give about 740 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Denny compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Denny.
| Town | kWh per kWp a year | vs Denny |
|---|---|---|
| Denny | 856 | this town |
| Bonnybridge | 862 | +6 kWh |
| Larbert and Stenhousemuir | 873 | +17 kWh |
| Falkirk | 867 | +11 kWh |
| Cumbernauld | 827 | −29 kWh |
| Stirling | 876 | +20 kWh |
| Kilsyth | 834 | −22 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.
