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.
