Solar Car Parks
Solar Car Parks for UK Businesses
A solar car park combines a free-standing canopy structure with integrated solar panels — generating clean electricity from your car park surface without sacrificing a single parking space. Self-consume on-site, export the surplus, and provide covered parking as a bonus.
Why build a solar car park?
A solar car park puts underused airspace to work. Your car park occupies thousands of square metres of flat paved surface — the canopy structure above it costs a fraction of a building footprint and generates electricity for 25+ years.
Generate electricity where you use it. Commercial electricity is now 22-28p/kWh. On-site solar generation replaces grid purchases at that rate. A 300 kWp solar car park producing 285,000 kWh annually saves £62,700-£79,800 per year at current rates.
Two assets for one capital spend. The structure provides covered parking — a measurable amenity for customers and staff — while the panels generate electricity. You get both for a capital cost below £1,400/kWp.
No roof constraints. Many commercial buildings have unsuitable roofs: asbestos cement sheeting, lightweight cladding, tenancy restrictions, or structural limitations. The car park canopy bypasses all of these. It creates its own structure over land you already own and use.
EV charging built in. Solar car park columns are the natural home for EV chargepoints. Running cables from panels above to chargers at bay level uses the same structural elements — one installation, two infrastructure upgrades.
Grid relief during peak demand. Solar generation peaks at midday when grid demand and electricity prices are highest. Self-consuming at peak cuts your maximum demand charge (MOP/MAP), which can reduce your standing charge on half-hourly meters.
What "solar car park" means in practice
The structure is a free-standing galvanised steel frame. Columns are driven or pile-founded into the car park surface. The frame carries cross-members at roof level, supporting purlins on which solar panels are clamped. The whole assembly is engineered to Eurocode wind and snow loading for your site's geographic location.
Three structure types are available: mono-pitch (single-slope, south-facing), T-frame (covering two rows from a central column row), and cantilever (high-clearance for HGV access). We design all three in-house.

How a solar car park project works
Free feasibility study
Send us your meter data and car park dimensions. We return a PVSyst yield model, 25-year financial DCF, and indicative structural scheme within 5 working days — no charge.
Site survey & detailed design
A structural engineer visits site (one day). We complete full Eurocode structural calculations, electrical single-line diagram, and a DNO G98/G99 grid connection application.
Planning & procurement
We submit the planning application or confirm permitted development status. Steelwork is fabricated and galvanised off-site in parallel with the planning determination.
Installation & commissioning
Foundations piled, columns erected, panels installed. Minimum 80% of car park spaces kept operational throughout. MCS commissioning certificate issued at handover.
Solar car park FAQs
Solar car park costs range from £900-£1,400 per kWp installed, depending on system size, structure type, and ground conditions. A 100-space car park typically yields a 300-400 kWp system costing £270,000-£560,000. Larger systems achieve lower per-kWp costs. See our full cost guide for detailed breakdowns by system size.
Most solar car park structures require full planning permission in England. Permitted development rights for car park canopies are limited — structures over 4 metres in height or covering more than 50% of a car park area typically need a full application. In Scotland and Wales, different thresholds apply. We handle the planning submission as part of our full-service offering.
Total programme from initial feasibility to commissioning is typically 4-9 months. The grid connection application (G99 for systems above 50 kWp) is the longest item, taking 8-26 weeks depending on DNO capacity. Physical installation takes 2-6 weeks. We start the grid connection application on day one of the design phase to minimise total programme time.
Yes — solar car park canopies are the ideal platform for EV charging. The structural columns provide natural cable routes from the solar panels above to chargepoints at bay level. We design integrated systems with 7 kW AC slow chargers, 22 kW fast chargers, and up to 150 kW DC rapid chargers. OZEV Workplace Charging Scheme grants of £350 per socket are available for eligible employers.
Solar car park payback periods range from 3.5-6 years for commercial installations at current UK electricity prices of 22-28p/kWh. The calculation depends on your self-consumption rate, export tariff, system size, and financing structure. Organisations using PPA or asset finance can achieve cash-positive returns from year one with no upfront capital.
You own it outright if you purchase the system. Alternatively, we offer power purchase agreement (PPA) structures where we own the solar car park and you buy the electricity it generates at a fixed below-market rate. Under a PPA, there is no upfront capital cost, no maintenance obligation, and you still benefit from reduced electricity bills and covered parking.
