Solar Canopy for Supermarket Car Parks

## Why Supermarkets Are Leading the Solar Canopy Market Supermarkets are the UK's largest commercial solar canopy opportunity segment. The combination of: - **Vast surface car parks** (often 200-800 spaces) - **High 24/7 energy demand** (refrigeration, HVAC, lighting never stops) - **Customer EV expectations** (supermarket car parks are a top-requested EV charging location) - **Net zero commitments from all major retailers** (Tesco 2035, Sainsbury's 2035, Asda 2035, Morrisons 2040) ...makes supermarket car park canopies some of the most financially compelling solar projects in the UK. ## Self-Consumption: The Supermarket Advantage A typical large supermarket consumes 2-5 MW continuously. Even a 1 MWp canopy generates only 20-50% of peak demand. This means self-consumption ratios on supermarket canopies routinely reach 95-99% — every kWh generated is immediately consumed, worth 22-28p/kWh in avoided grid cost. Compare this to a 9-5 office building where 30-40% of solar output is exported at SEG rates. The supermarket economics are fundamentally better due to load matching. ## Customer EV Charging Integration Supermarkets are under increasing pressure from customers and regulators to provide EV charging. A solar canopy with integrated EV chargers creates a closed loop: - Customers park and charge while shopping (typically 30-90 minute dwell) - 7 kW AC chargers under the canopy add 7-10 miles of range per 15-minute shopping trip - Supermarket can offer free charging as a loyalty differentiator, funded by solar revenue - Or charge at 38-45p/kWh (below public rapid charger rates) as revenue stream ## Planning for Supermarket Solar Canopies Most supermarket car parks are in edge-of-town or out-of-town locations under the planning remit of the district or borough council. Permitted Development applies in most cases. Pre-application advice is recommended for canopies exceeding 250 kWp or where the canopy would be visible from a trunk road. Supermarket landlords (British Land, Hammerson, Legal & General, Aviva) are generally supportive — solar canopies improve asset value and contribute to GRESB and BREEAM In-Use ratings. ## Sizing Guide for Supermarket Car Parks | Car park size | Recommended canopy | Est. annual generation | Est. annual saving | |---|---|---|---| | 200 spaces | 300 kWp | 285,000 kWh | £62,700 | | 400 spaces | 600 kWp | 570,000 kWh | £125,400 | | 700 spaces | 1,050 kWp | 997,500 kWh | £219,450 | *Based on Midlands irradiance, 22p/kWh, 96% self-consumption.* ## Get a Supermarket Canopy Quote We work with supermarket operators, landlords, and property funds. We understand the operational constraints (delivery vehicle access, trolley bay clearances, CCTV integration) and can deliver projects without disruption to store operations. Installations are phased to avoid closing more than 20% of car park spaces at any time.
