Commercial solar installers in Greenock

Key facts

Where businesses are in Greenock

• Inchgreen Marine Park: Riverside site on the Clyde run by a joint venture of Peel Ports Clydeport and Inverclyde Council, next to the Inchgreen Dry Dock. An £11m upgrade finished in February 2024 brought new roads and utilities, upgraded quay walls, dredging and a refurbished Platers' Shed.
• Lynedoch Industrial Estate: Secure industrial estate off Dellingburn Street close to Greenock town centre, run by Riverside Inverclyde Property Holdings, with 21 stand alone and terraced units of 1,600 to 15,000 sq ft.

Large employers and sectors with sites here include:

• Cruise tourism (Greenock Cruise Port): In March 2025 Global Ports Holding signed a 50 year agreement with Clydeport Operations to run Greenock Cruise Port, which handled over 80 cruise calls in 2024.
• Marine engineering (Inchgreen Dry Dock): The Autumn 2025 Budget promised £20m to renew infrastructure at Inchgreen, building on £9.77m from the Glasgow City Region Deal, and HM Treasury says it will create up to 1,750 jobs, including 350 direct roles.

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

Greenock 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 Greenock

Planning in Greenock is decided by Inverclyde 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 Greenock West End Conservation Area covers about 126 hectares, so check whether a building is inside it before planning roof panels in the west of the town.
• 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 Greenock could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 854 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.
