Against Great Britain as a whole: Rosyth makes 895 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Rosyth is 3% below it.
How Rosyth compares
Small towns rarely get published solar figures, so here are the numbers for Rosyth. It is one of 10 Fife towns we track, and it ranks 6th of 10 for solar yield, a town of 13,148 people in the House of Commons Library settlement data. PVGIS gives its roofs 895 kWh per kWp a year, 2.45 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £818 of year one benefit, £247 of it from your own generation and £571 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Rosyth'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.
Any planning application in Rosyth sits with Fife, 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 Rosyth
Rosyth is served by SP Energy Networks: the town's centre falls inside its South and Central Scotland licence area on NESO's boundary map.
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.

Heat pumps and EV charging in Rosyth
A heat pump in Rosyth
In December, the darkest month here, 12 panels in Rosyth make about 140 kWh. That is when a heat pump runs hardest, so its running cost in Rosyth 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 Rosyth
Rosyth'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.
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.

Solar in Rosyth: your questions answered
How much energy would 12 solar panels make in Rosyth?
Rosyth averages 2.45 peak sun hours a day, which PVGIS turns into 895 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,690 kWh, 71% of it between April and September.
Is solar more expensive in Rosyth?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Rosyth, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,690 kWh a year here, which is what drives payback.
Who is the network operator in Rosyth, and do I need a G99 application?
The operator is SP Energy Networks. Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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. Your design call checks which route yours needs.
What could I earn from exporting in Rosyth?
On the 12p export scenario, a 12-panel system in Rosyth sends about 4,756 kWh a year to the grid, worth around £571. The export rates table compares what each supplier pays.
How does solar perform in Rosyth in the winter months?
December is the weakest month in Rosyth: about 140 kWh from 12 panels, against 780 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Rosyth compares with its neighbours
How the towns nearest Rosyth compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Rosyth |
|---|---|---|
| Rosyth | 895 | this town |
| Dalgety Bay | 896 | +1 kWh |
| Dunfermline | 892 | −3 kWh |
| Queensferry | 896 | +1 kWh |

| Broxburn | 848 | −47 kWh |
| Bo'ness | 869 | −26 kWh |
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.
