Large, simple roofs on distribution sheds and modern industrial units are usually the quickest and cheapest to fit. Older mill, factory and workshop buildings can work well too, but often need a structural survey first, and roofs from before 2000 may contain asbestos cement: see asbestos roofs.
Grid connection
Ardrossan is served by SP Energy Networks (SP Distribution, Central and Southern Scotland). Almost every commercial system needs G99 approval from the network operator before it is switched on, and the question is usually how much the local network can take back. Where export is limited, a G100 export limitation scheme can let a larger array connect. See G99 and DNO applications.
Planning in Ardrossan
Planning in Ardrossan is decided by North Ayrshire council under Scotland's own system. Non-domestic rooftop solar is often permitted development under the Scottish rules, but not on listed buildings, in National Scenic Areas or within 3 km of an aerodrome.
Points that come up locally:
- Since 24 May 2024, Scotland's Class 6J lets solar panels go on non-domestic buildings without planning permission if they stand no more than 1 metre from the surface of the building, but not on a listed building or within its curtilage, nor, in a conservation area, on the front elevation or a side elevation fronting a road.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Ardrossan could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 884 kWh per kWp a year.
| Item | Illustrative figure |
|---|---|
| System | 100 kWp, south facing at 30 degrees |
| Installed cost | £900 per kWp, so £90,000 excluding VAT |
| Generation | About 88,400 kWh a year |
| Used on site | 70% at 24p = £14,851 saved |
| Exported | 30% at 5p = £1,326 earned |
| Total a year | About £16,177 |
| Simple payback | About 5.6 years before tax relief |
Illustrative, not a quote: the same sums as our commercial solar calculator. A company paying corporation tax can usually shorten the payback with capital allowances.
