Solar Carports for Retail & Supermarket Sites
Cover customer car parks, slash store energy bills, and offer free EV charging as a footfall driver.
Sector economics
UK retail and supermarket car parks represent the single largest under-utilised commercial surface in the UK — over 9,000 supermarket sites and 1,200+ retail parks averaging 250-700 spaces each. A solar carport over a retail car park combines real-estate yield, energy hedge, ESG credentials and a customer-experience uplift.
Recent Retail & Supermarket Car Parks Case Study
A regional supermarket chain operating 38 stores across the South of England targeted a £6.5m portfolio carport rollout in 2024-25. We delivered four pilot stores totalling 1.8 MWp — Romford, Reading, Bracknell and Gravesend. Combined annual generation: ~1.53m kWh. Combined annual electricity saving: £685,000. Each store now offers 6 × 22 kW free customer EV chargers as a footfall driver.
Sector-Specific Design
- Bay layout typically 2.4m × 4.8m — carport span 5m to clear bay markings
- Trolley return shelters integrated into carport columns where space allows
- Customer EV chargers at one in every 8 bays — 22 kW for short dwell
- Architectural styling matched to existing store branding (powder-coat colour)
- PV array oriented for peak generation during trading hours
Standards & Frameworks
- BBSI BPM-001 (Best Practice for Solar Installation on Retail Premises)
- ACS Energy Code of Practice for retail energy management
- BREEAM Excellent retrofit credits (5-7 ENER credits typical)
- ASDA-Walmart Sustainability Reporting Framework alignment
- Tesco Stronger Starts Net Zero supplier disclosure
How to Pay for It
Retail carports rarely qualify for PSDS (public-sector only). The two main routes are (1) AIA on capital deployment, (2) commercial PPA — particularly attractive for retailers with stretched balance sheets. Major UK supermarkets are also building portfolio PPAs internally via parent-company project SPVs.
