Commercial solar installers in Oban

Key facts

Where businesses are in Oban

• European Marine Science Park, Dunstaffnage: Marine science park beside SAMS near Oban, developed by Highlands and Islands Enterprise. Malin House holds 13 companies and around 70 employees, and the £8.1m Camas House, with seven laboratories and seven office suites in about 1,500 square metres, was completed in May 2026.
• Glenshellach Industrial Estate: Industrial estate that Highlands and Islands Enterprise extended in 2018 with a new access road and four serviced plots; its November 2024 asset list still showed vacant serviced plots there and at Glenshellach Business Park.

Large employers and sectors with sites here include:

• Marine science (SAMS): The Scottish Association for Marine Science, three miles north east of Oban, describes itself as Scotland's largest and oldest independent marine science organisation and says it employs over 160 staff.
• Ferries and port (CalMac): CalMac describes Oban as Scotland's busiest port, with ferries to Mull, Lismore, Coll, Tiree, Colonsay, Barra and, in winter, South Uist.

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

Oban is served by SSEN Distribution (Scottish Hydro Electric Power Distribution, North of Scotland licence area). 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 Oban

Planning in Oban is decided by Argyll and Bute 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:

• Oban is not among Argyll and Bute's 33 conservation areas, so conservation area rules rarely affect business roofs in the town, though listed buildings still need consent.
• Since 24 May 2024, Scotland's Class 6J lets solar PV go on non-domestic buildings without planning permission if it protrudes no more than 1 metre, but not on a listed building or within its curtilage, within 3 km of an aerodrome or technical site, or, in a conservation area, on the principal elevation or a side elevation fronting a road.

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

What a business roof in Oban could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 803 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
