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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Planning is easier on a canopy. Listed buildings and conservation areas often rule out rooftop solar but allow canopies in the curtilage car park.
  6. 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.

Before you commission

Why canopy projects are different

Canopies are a different engineering challenge. Here's why that matters to your project.

A canopy is the structure

A rooftop array bolts onto a building that already exists. A canopy is a steel frame on its own foundations, designed for wind and snow loading under BS EN 1991 and for vehicle clearance — so the engineering, not the panels, drives much of the cost and most of the risk.

Check who holds the contract

Design, planning, structural engineering, foundations, steel, electrical work, the grid connection and EV chargers can sit with one principal contractor or be split between several. One contract removes coordination gaps; a split one needs a named owner for the foundation-to-frame interface.

Plan the build around the car park

A canopy can usually be built one row at a time, so only a section of the car park is closed at any moment. Agree the programme around your busiest trading or operational periods before you sign.

The process

How a canopy project runs

From the first desk check to a commissioned system — the usual sequence.

01

Free desk feasibility

Send your half-hourly meter data and a plan of the car park. We return an indicative system size, a generation estimate, a payback model and a check of which funding routes genuinely apply — within 5 working days. No site visit, no fee.

02

Site survey & ground investigation

The installer you appoint surveys the site: topography, the electrical intake and trial pits for the ground conditions. The ground investigation drives the foundation design, and it is usually the point at which a firm price can be fixed.

03

Planning, DNO & structural sign-off

The consents a canopy has to clear: planning permission where permitted development does not apply, a G99 connection application to the network operator, and an independent structural check of the frame and foundations. Each is explained before you commission anyone.

04

Build, commission & handover

Canopies are normally built a row at a time, so most of the car park stays open. Foundations, steel, panels, electrical work and EV chargers follow in sequence; the installer then commissions and registers the system, and the product and workmanship warranties run from handover.

Sizing & cost

Solar canopy cost and output by car park size

Engineered to UK and European structural codes

Our structural engineers run every canopy through the full Eurocode stack — EN 1990 (basis of design), EN 1991 (wind, snow and imposed loads) and EN 1993 (steel design) — with site-specific wind and snow data, not generic assumptions. Foundations are sized off geotechnical trial pits, so a canopy on made-ground in Birmingham is designed differently from one on chalk in Kent.

  • Watertight PV roof. Modules form a fully sealed, guttered roof — covered, dry parking, not just a panel rack.
  • Posts within rafters. Low-profile columns sited on bay lines preserve every parking space and meet DDA access widths.
  • Independent Cat 3 check. Every structural design is independently verified before fabrication.

Where solar canopies fit best

Canopies make most economic sense at sites with substantial paved area, reasonable daytime electricity demand, and a reason rooftop PV isn't the obvious choice. The eight property types where we see canopies deliver hardest:

  • Supermarkets. Continuous daytime baseload, large car parks, customer-facing brand benefit, EV-charging pledge alignment.
  • Retail parks. Multi-tenant private wire networks, PPA-friendly, EV revenue stream. The sweet spot for double-cantilever.
  • NHS and hospital sites. 24/7 baseload means near-100% self-consumption. That load profile, not a grant, is the capital case: PSDS closed to new bids in November 2024.
  • Universities. Large car parks, public sector decarbonisation funding, visible sustainability brand statement.
  • Business parks & HQ. Employee benefit (covered parking), EV charging, ESG visibility for HQ-located corporates.
  • Hotels. Guest differentiator, reduced grid dependency on summer AC peak, premium brand positioning.
  • Schools and academies. MAT-wide rollouts increasingly common; one canopy delivers covered waiting, EV staff charging, and STEM teaching aid.
  • Local authority car parks. Public-facing decarbonisation; EV revenue offsets fee dependency. Funded from capital or borrowing since PSDS closed in November 2024.

Case studies

Worked project models

Supermarket double-cantilever canopy with EV charging

A 4,500 m² mid-Northern supermarket needed to deliver 12 EV chargers to meet a customer-pledge commitment but had insufficient roof space and tenanted upper-floor offices that ruled out rooftop solar. We designed and installed a 425 kWp double-cantilever canopy across 92 parking bays, integrating 12 × 22 kW AC and 4 × 50 kW DC chargers with OCPP back-office. The canopy generated 405,000 kWh in year one, offset 73% of the store's daytime demand, and the EV chargers added a £40,000/year revenue line. The store reported a 2.3% footfall uplift in the first 6 months, attributed by their customer survey to covered parking and EV provision.

NHS Trust hospital staff and visitor canopy

An NHS Foundation Trust in the Midlands secured PSDS Phase 3b funding for a 240 kWp solar canopy across the main staff and visitor car park (52 bays of double-cantilever). The hospital's main building roof was ruled out due to a planned reroofing programme and infection-control restrictions on rooftop access. The canopy delivers 228,000 kWh per year directly into the hospital's continuous baseload, including theatres, ITU, and pathology. Eight 22 kW chargers serve EV-pool ambulances and visitor bays. PSDS covered 100% of capital cost; the Trust banks the entire £36,000/year energy saving plus EV charging revenue.

Retail park multi-row canopy with brand integration

A 12-unit retail park in Greater Manchester deployed a 1,150 kWp solar canopy across 280 parking bays — 7 rows of double-cantilever with integrated downlighting and tenant brand signage. The canopy delivers electricity into a private wire network that feeds all 12 retail tenants under a 25-year PPA at 13p/kWh (vs grid retail of 24p+). 24 EV chargers (8 × 50 kW DC and 16 × 22 kW AC) generate £180,000/year in usage revenue. The canopy was designed in 6 RAL colours matching tenant brands and includes uplit signage on the central column row. Construction was phased over 14 weeks with no full-park closure.

Common canopy questions

What is a commercial solar canopy?

A commercial solar canopy is an engineered free-standing steel structure — typically over a car park, walkway, or open 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 condition. Canopies range from 30 kW single-bay carports through to multi-megawatt installations spanning hundreds of bays at supermarkets, retail parks, and hospitals.

How much does a commercial solar canopy cost?

Installed cost is typically £900–£1,400 per kWp depending on scale, ground conditions, and EV charging integration. A 100 kWp canopy (about 22 bays) is £100,000–£140,000; a 500 kWp canopy is £450,000–£650,000; a 2 MW double-cantilever array is £1.8m–£2.6m. Foundations, ground conditions, and architectural finishes are the main cost drivers.

Do I need planning permission for a solar canopy?

Often no. Permitted Development rights under Class A.2(b) of the GPDO 2015 cover many commercial canopies under 9m and within 5m of the host building. Larger canopies, conservation areas, listed buildings, and sites near boundaries usually need full planning permission. We handle the LPA submission as part of every project.

Can I integrate EV charging into a solar canopy?

Yes — EV-integrated canopies are now the most common configuration we deliver. We integrate 7 kW AC, 22 kW AC, or 50–150 kW DC chargers under the canopy, wired through the same private network. OCPP back-office providers like Monta, Pod Point, Mer, or Allego run the chargepoint network. The OZEV Workplace Charging Scheme grant (£500 per socket since 1 April 2026, up to 40 sockets, scheme ends 31 March 2027) covers part of the EV cost.

How long does a solar canopy installation take?

Typical project timelines: 4–6 weeks for design and planning approval; 6–8 weeks for procurement and DNO consent; 4–14 weeks on site depending on size. For a 100 kWp canopy that's 4–5 months end-to-end; for a 1 MW double-cantilever array, 7–9 months. We work in phased rows so the car park stays operational throughout.

What is the payback on a commercial solar canopy?

Capital purchase paybacks are typically 7–9 years for canopies, versus 4–6 years for rooftop PV. The longer payback reflects the higher £/kWp from steel structure and foundations. EV-integrated canopies typically pay back faster due to chargepoint revenue. PPA structures deliver day-one positive cash with no capital outlay.

How much does a solar canopy cost per parking space?

As a rule of thumb a commercial solar canopy costs roughly £4,000–£5,500 per parking bay, equating to £900–£1,400 per kWp installed at a typical 3–4 kWp per bay. A 10-bay canopy lands around £40k–£55k and a 50-bay around £160k–£230k. Ground conditions, clearance height and EV charging integration move the figure within that band. See our full breakdown on the solar canopy cost guide.

How many solar panels fit per parking bay on a canopy?

A standard single parking bay carries 6–8 modules at 440–600 W, giving about 3–4 kWp and 1,500–3,000 kWh of generation a year in the UK. Double-cantilever (back-to-back) bays roughly double that per structural row. Exact panel count depends on bay width, module size and whether the canopy is single-slope or duo-pitch.

What is the difference between a solar canopy and a solar carport?

They are the same engineered structure described from two angles. 'Solar carport' emphasises the covered-parking function; 'solar canopy' emphasises the free-standing PV roof, which can also span walkways, entrances and paved areas rather than only car parks. We design and install both — a free-standing steel structure carrying solar PV as its roof.

What structural standards are solar canopies designed to?

UK commercial solar canopies should be engineered to the Eurocode stack: EN 1990 (basis of structural design), EN 1991-1-3 and 1991-1-4 (snow and wind loading) and EN 1993 (steel design), with steelwork hot-dip galvanised to BS EN ISO 1461. We size foundations from site-specific geotechnical data and run an independent Category 3 structural check before any steel is fabricated.

Are solar powered parking canopies worth it for commercial sites?

For sites with large car parks and daytime electricity demand, yes — solar powered parking canopies typically pay back in 6–10 years, run for 25+ years, and add EV charging at the point of generation. They also deliver covered parking, visible ESG credentials and, for public-sector bodies, a visible decarbonisation project — though the Public Sector Decarbonisation Scheme closed to new applications in November 2024 and was its final phase, so public bodies now fund canopies from capital budgets, borrowing or a power purchase agreement. They make less sense where a usable roof could host the same array more cheaply.
