Against Great Britain as a whole: Glenrothes makes 903 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Glenrothes is 2% below it.
How Glenrothes compares
Among the places we publish figures for, Glenrothes is one of 10 Fife towns we track, and it ranks 3rd of 10 for solar yield. It is a medium town in the House of Commons Library classification, with 35,767 residents, and its roofs see 2.47 peak sun hours a day across the year. That drives the standard 12 panel model to 5,743 kWh of generation, of which around 4,806 kWh is exported at 12p for £577 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Glenrothes' 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.
Planning applications here go through Fife; nationally, the House of Commons Library classes Glenrothes as a medium 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.

SP Energy Networks and your Glenrothes connection
SP Energy Networks owns and runs the local electricity network in Glenrothes, as part of its South and Central Scotland licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SP Energy Networks is notified within 28 days of switch-on rather than asked beforehand.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Glenrothes
A heat pump in Glenrothes
In December, the darkest month here, 12 panels in Glenrothes make about 140 kWh. That is when a heat pump runs hardest, so its running cost in Glenrothes 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 Glenrothes
Summer is where a car earns its place. In May, 12 panels in Glenrothes make about 800 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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 Glenrothes
How much electricity do solar panels make in Glenrothes?
About 5,740 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Glenrothes: 903 kWh per kWp, or 2.47 peak sun hours a day on average. May is the strongest month, at about 800 kWh.
What does a typical solar system cost in Glenrothes?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Glenrothes, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,740 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Glenrothes, and what does it need from me?
SP Energy Networks covers Glenrothes. 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 happens to the solar I do not use in Glenrothes?
Around £577 a year at 12p per kWh, for the roughly 4,806 kWh a 12-panel system in Glenrothes exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Glenrothes get in December?
December is the low point: about 140 kWh from a 12-panel system in Glenrothes, on PVGIS data, rising to 800 kWh in May. From November to February the same system makes about 840 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Glenrothes 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 Glenrothes |
|---|---|---|
| Glenrothes | 903 | this town |
| Methil | 890 | −13 kWh |
| Kirkcaldy | 880 | −23 kWh |
| Leven | 894 | −9 kWh |
| Cowdenbeath | 899 | −4 kWh |
| Cupar | 940 | +37 kWh |
| Dalgety Bay | 896 | −7 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.
