Quick answer
What are solar canopies?
Solar canopies (also called solar carports or solar car park canopies) are free-standing steel structures that carry solar PV modules as their roof, built over car parks, walkways or paved areas. Commercial solar canopies typically generate 3–4 kWp per parking bay, cost £900–£1,400 per kWp installed, and pay back in 6–10 years while leaving every parking space usable. Unlike rooftop solar, a solar PV canopy is independent of the host building's roof age, lease or structure and integrates EV charging at point of generation.
What we do
What a commercial solar canopy actually is
A commercial solar canopy is an engineered free-standing steel structure — typically built over a car park, walkway, or paved area — that carries solar PV modules as its roof. Unlike rooftop PV, a canopy doesn't depend on the host building's structure or roof age. It's a standalone array carried on its own foundations and steel columns, with photovoltaic glass forming the roof. The car park stays a car park; the walkway stays a walkway. What changes is that the same square metres now generate electricity.
This site is an independent UK resource for the canopy niche, published by SEO Dons Ltd — we are not an installer. It covers canopy systems from 30 kW single-bay carports through to 5 MW multi-row supermarket and retail-park installations. A well-specified commercial canopy is engineered to BS EN 1991, installed and registered by an MCS-certified contractor, connected under a G99 application, and backed by product and workmanship warranties. EV charging, rainwater harvesting and LED lighting are common additions.
Canopies are a different engineering job from rooftop solar. The structural design, foundation calculation, consent route and EV charging integration all sit outside the everyday work of installers whose business is rooftop retrofits — which is why it is worth asking any installer for canopy projects they have built, and checking them.
For the technical detail: our solar panel canopy guide covers panel type selection (Mono PERC vs TOPCon bifacial vs HJT), bifacial yield models, and structure options. Our car park solar panels guide explains output by car park size, system specifications, and the canopy-vs-rooftop comparison in full. Our installation process guide covers the 12–18 week programme from feasibility to MCS commissioning.
Why a canopy instead of rooftop solar?
The vast majority of UK commercial solar projects we model can be delivered on a roof more cheaply than via a canopy — typically £700–£900/kWp on a roof versus £900–£1,400 on a canopy. So why does the canopy market exist at all? Six honest reasons:
- ✓ The roof isn't an option. It's leased, near end-of-life, asbestos-bonded, structurally limited, or shared with a planning constraint that rules out PV.
- ✓ You need EV charging anyway. Integrating EV chargers under a solar canopy is significantly cheaper per charger than building separate chargepoint infrastructure, and the energy is generated at point of use.
- ✓ Covered parking is a benefit. Supermarkets see measurable footfall uplift from covered parking. Hospitals and universities see staff retention impact. Hotels position it as a brand feature.
- ✓ The roof is owned by someone else. If you lease the building, a canopy on your demised car park is your asset. End-of-lease dilapidations don't apply.
- ✓ Planning is easier on a canopy. Listed buildings and conservation areas often rule out rooftop solar but allow canopies in the curtilage car park.
- ✓ You want the investment visible. A canopy is the most visible solar investment a brand can make. For organisations with public-facing ESG commitments, that visibility matters.
