Solar Carports Generate Energy from Your Car Park
A solar carport turns underused car park space into a productive energy asset - generating solar electricity, providing covered parking and creating a ready-made infrastructure for EV charging, all in a single structure.
Overview
About Solar Carports
For commercial properties with surface car parks – retail parks, business parks, industrial estates, distribution centres, leisure facilities and education campuses – solar carports offer a way to generate solar electricity without using any roof space. The car park surface that currently generates no commercial return becomes a solar generation asset, while simultaneously improving the amenity of the car park for users.
Caledonia Solar designs, funds and delivers commercial solar carport structures across Scotland and the wider UK. We manage the full project – structural engineering, planning, electrical design, grid connection, funding and installation – through a single point of contact.
A solar carport is the only commercial solar structure that simultaneously generates energy, improves car park amenity and creates EV charging infrastructure – making it one of the most commercially productive uses of surface car park space available to Scottish businesses.
For many commercial properties, a solar carport is the only way to add meaningful solar capacity once rooftop space has been exhausted – turning a static asset into a productive one without any change to the building itself.
How commercial solar reshapes your energy P&L
A well sized commercial solar installation typically displaces 60 to 80 percent of daytime grid consumption. 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.
Key Benefits
Why commercial solar carports are gaining ground in Scotland and the UK
Solar carports work independently of the building roof, meaning businesses with limited, shaded or structurally constrained rooftops can still generate substantial solar capacity from car park space.
The structural frame of a solar carport provides the ideal mounting point for EV charging equipment, with the solar generation directly powering the charging infrastructure. As fleet electrification accelerates, a combined solar and EV charging carport positions the property for the next decade of transport decarbonisation.
Users benefit from covered parking in all weather conditions - a meaningful amenity improvement for staff, customers or visitors that supports occupier satisfaction and property value.
For businesses that have already maximised rooftop solar, carport structures provide additional generation capacity from an otherwise unproductive asset.
Solar carports on existing car park surfaces are generally viewed more favourably in planning terms than equivalent ground-mounted systems, as they do not occupy greenfield land or significantly alter the existing land use.
For commercial properties with surface car parks, solar carports represent an untapped generation opportunity - the infrastructure already exists, it simply is not yet working.
Specifications
Typical specifications
All figures are indicative only. Caledonia Solar will provide a full specification for your specific site.
Solar carport structures are designed and engineered to BS EN 1990 structural standards and specified for Scottish wind and snow loading conditions, which differ materially from southern England specifications. Caledonia Solar engages a structural engineer on every carport project.
Planning
Planning considerations
Solar carport structures in Scotland typically require a planning application rather than benefiting from permitted development rights, as they constitute a new structure rather than a modification to an existing building. The planning position depends on the specific site, local development plan, proximity to listed buildings or conservation areas, and the scale of the proposed structure.
Caledonia Solar manages the planning application process on behalf of clients, including preparation of design and access statements, structural drawings and heritage impact assessments where required. Planning timescales for commercial solar carport applications in Scotland are typically 8–16 weeks from submission.
Funding
Three ways to fund Solar Carports
Solar carport projects are funded through the same three routes available for rooftop installations – CapEx purchase, asset finance and Power Purchase Agreement. For larger carport projects combined with EV charging infrastructure, specialist infrastructure finance is also available. Caledonia Solar models all available funding routes and presents a comparative financial assessment before any commitment.
Buy the system outright. The highest lifetime return and full ownership of the asset and all the energy it generates from day one.
Spread the cost over a fixed term and preserve working capital. The system typically pays for itself from the energy savings it delivers.
Zero upfront cost. A funding partner owns the system and you simply buy the solar power it produces, at a rate below the grid.
