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.
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.
Why commercial solar carports are gaining ground in Scotland and the UK
No roof space required: 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.
EV charging integration: 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.
Covered parking amenity: 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.
Additional solar capacity: For businesses that have already maximised rooftop solar, carport structures provide additional generation capacity from an otherwise unproductive asset.
Planning advantage: 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.
System size range: 50kW – 500kW+ depending on car park area and structural configuration
Typical car park coverage: one standard car parking bay supports approximately 2–4 solar panels, generating 600W–1.4kW of capacity per bay
Structure type: galvanised steel mono-pitch or dual-pitch canopy structures, engineered to Scottish wind and snow loading requirements
EV charging: up to one charge point per parking bay within the carport footprint
Typical project value: £80,000 – £600,000+ depending on scale and EV charging specification
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 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
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.
Frequently asked questions
Does a solar carport need planning permission in Scotland?
In most cases, commercial solar carport structures in Scotland require a planning application as they constitute a new above-ground structure rather than a modification to an existing building. Unlike rooftop solar, carports do not typically benefit from permitted development rights. Planning requirements vary by local authority, proximity to listed buildings and the scale of the proposed structure. Caledonia Solar manages the planning application process on behalf of every carport client and can advise on the likely planning position for a specific site.
Can a solar carport power EV charging points?
Yes — and this is one of the most compelling arguments for a solar carport rather than a standard ground-mounted system. The structural frame provides the mounting point for EV charging equipment, and the solar generation directly supplies power to the charge points. In periods of high solar generation, charging can be powered entirely by solar electricity at near-zero cost. Caledonia Solar designs combined solar carport and EV charging systems, sized to the anticipated charging demand of the car park.
How many solar panels can fit on a commercial car park?
A standard car parking bay of approximately 2.4m x 4.8m can accommodate 2–4 solar panels depending on the carport structure design and panel orientation. A 50-bay car park can typically support 100–200 panels, generating 35–70kW of installed capacity. Larger car parks of 200+ bays can support installations of 150–300kW+. Caledonia Solar produces a capacity assessment for every carport enquiry based on the specific car park layout, dimensions and orientation.
