Commercial solar installers in Glenrothes

Key facts

Where businesses are in Glenrothes

• Southfield Industrial Estate: Estate on the southern outskirts of Glenrothes whose occupiers include NOV Flexibles, Quality Precision Electronics, Keela, Malcolm Logistics and Eurospray.
• Viewfield Industrial Estate: Established estate with links to the A92, whose occupiers include FTV Proclad, Leviton Network Solutions and Bosch Rexroth.
• Queensway Technology and Business Park: Business location on the eastern edge of Glenrothes where City Region Deal funding paid for refurbishment and nine new business units. Occupants include Audio Emotion, McDonalds Water Storage and Plastech Group.

Large employers and sectors with sites here include:

• Defence electronics (Raytheon UK): Raytheon UK's Glenrothes site in the Queensway Industrial Estate provides avionics systems, electronic contract manufacturing and security identification systems, according to Fife Council's investment prospectus.
• Fibre optics and hydraulics (Leviton, Bosch Rexroth): Fife Council's prospectus names Leviton, a fibre optics manufacturer for telecoms and data networks, and Bosch Rexroth, a hydraulics maker, among the town's manufacturers.
• Renewable energy (RWE Markinch): RWE's Markinch biomass combined heat and power station supplies renewable heat to the Glenrothes Energy Network, a district heating scheme for businesses and homes in the town centre.

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

Glenrothes 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 Glenrothes

Planning in Glenrothes is decided by Fife 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:

• The conservation areas around Glenrothes are small: Leslie covers about 24.4 hectares, Cadham Village about 7.1 hectares and Markinch about 6.9 hectares, so check whether a building is inside one before planning roof panels.

Our guides on listed buildings and conservation areas explain what these mean for a solar project.

What a business roof in Glenrothes could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 904 kWh per kWp a year.

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.

Funding and support
