Commercial Solar Renfrewshire Hillington, Glasgow Airport and Paisley
Renfrewshire’s concentration of airport-adjacent logistics, manufacturing and technology businesses - from Hillington Park to Inchinnan Business Park - creates a strong and growing commercial solar market on Glasgow’s western boundary.
Local Commercial Landscape
Commercial & Industrial Activity in Renfrewshire
Renfrewshire sits immediately west of Glasgow, bordered by the M8 to the north and the River Clyde to the east, with Glasgow Airport at its commercial hub and Hillington Park - one of the UK’s largest business parks - straddling the Glasgow-Renfrewshire boundary.
Renfrewshire sits immediately west of Glasgow and is home to some of Scotland’s most commercially significant business parks. Hillington Park – one of the UK’s largest business parks – straddles the Glasgow-Renfrewshire boundary and contains thousands of commercial and industrial units. Glasgow Airport Business Park and the Inchinnan development area host a growing cluster of aerospace, logistics, technology and professional services businesses. Paisley town centre and the surrounding retail and commercial zone add further commercial solar opportunity. Renfrewshire is served by SP Energy Networks. The grid infrastructure across Hillington, Inchinnan and the airport corridor is well-developed, reflecting the area’s long history as an industrial and commercial centre. Caledonia Solar manages all SP Energy Networks G99 applications for Renfrewshire installations from initial enquiry through to grid connection.
Renfrewshire’s combination of one of the UK’s largest business parks at Hillington, growing airport-adjacent logistics capacity and a strong manufacturing base makes it one of the highest-potential commercial solar markets in Scotland outside Glasgow city itself.
Across Hillington Park and the Glasgow Airport corridor, commercial and industrial businesses are increasingly using solar to lock in lower energy costs - with Renfrewshire’s proximity to Glasgow making it one of the most commercially active solar markets in the west of Scotland.

Commercial solar installations in the Renfrewshire area
Caledonia Solar works with commercial and industrial businesses across the following locations and business parks in this area:
This list is not exhaustive. If your business is based in the area and not listed, please contact us - we cover all commercial premises within the region.
A well sized commercial solar installation typically displaces 60 to 80 percent of daytime grid consumption, with the strongest yield months running from April through September. Over a 25 year system life, businesses on standard commercial tariffs see total energy spend reduce by hundreds of thousands of pounds depending on system scale and consumption profile.
Why Solar Works Here
Commercial solar PV in Renfrewshire - what you need to know
With over 500 business units, Hillington Park is one of the UK’s largest business parks and represents a concentration of commercial solar opportunity unmatched in any single location in Scotland.
Glasgow Airport’s cargo and logistics operations are growing, driving demand for large distribution and cold chain facilities in the airport corridor that are prime solar candidates.
Inchinnan and the airport corridor have attracted aerospace, defence and advanced manufacturing businesses whose energy-intensive operations create strong solar economics.
Renfrewshire’s established commercial zones are well-connected to the SP Energy Networks network, with many parks served by dedicated substations.
Most commercial rooftop solar installations in Renfrewshire benefit from permitted development rights under the May 2024 reforms. Hillington Park alone contains more potential commercial solar rooftop space than many entire Scottish towns - yet solar penetration across the park remains low. The opportunity is substantial and largely untapped. In Renfrewshire, with Hillington Park offering more potential commercial solar rooftop space than many entire Scottish towns, the opportunity for businesses to gain a structural energy cost advantage through solar is among the largest available anywhere in Scotland.

System Scale & Process
How a commercial solar project in Renfrewshire comes together
Commercial solar installations in the Renfrewshire area follow the same design, funding and installation process as all Caledonia Solar projects across Scotland. The grid connection application is submitted to SP Energy Networks, which typically takes 6–12 weeks from submission. Caledonia Solar manages the full G99 application process on your behalf.
- Typical system range for commercial buildings in this area: 50kW – 1MW+
- Grid connection: SP Energy Networks - G99 application required for systems above 16A per phase
- Planning authority: Renfrewshire Council - most rooftop installations benefit from permitted development rights under the May 2024 reforms
- Funding: CapEx, Asset Finance and PPA all available - Caledonia Solar models all three routes for every project
A typical 200kW commercial solar installation at Hillington Park or the airport corridor delivers 25–45% on-site energy offset, reducing annual electricity costs by £13,000–£30,000 at current tariffs.
Payback profile and return on investment
Commercial solar payback windows have compressed significantly as grid tariffs have risen and PV component costs have fallen. CapEx purchase typically pays back in 4 to 6 years on Scottish commercial sites, with full 25 year IRR commonly in the 12 to 18 percent range. Asset finance and PPA structures shift this profile but maintain net positive cash flow from year one.
