Solar Canopy for Retail Parks

## Retail Parks: The UK's Largest Solar Canopy Opportunity Out-of-town retail parks represent one of the largest untapped commercial solar canopy markets in the UK. The typical retail park has: - 200-1,000+ car parking spaces in a large flat surface park - Multiple retail tenants with high daytime HVAC and lighting loads - A landlord seeking to improve GRESB, BREEAM In-Use, and EPC ratings - Growing tenant and customer demand for EV charging - Planning authority support for renewable energy on commercial sites The UK has approximately 1,100 retail parks with over 50 units (British Council of Shopping Centres). If even 10% installed solar canopies at an average of 500 kWp, that would be 55 GWp of new generating capacity — enough to power 13 million homes. ## Retail Park Ownership Structure and Solar Retail parks are typically owned by: - **Major property funds** (CBRE, Savills, PGIM, Legal & General, Aviva): Motivated by GRESB ratings (solar directly improves Green Star criteria), sustainability reporting, and asset value improvement - **Private equity vehicles** (Blackstone, Brookfield): Motivated by NOI improvement and exit value enhancement - **Owner-occupiers** (retail groups operating freehold): Motivated by energy cost reduction and sustainability commitments In all cases, we can structure the project to work with the ownership and tenancy structure. For multi-let retail parks, we use a virtual net metering approach similar to our industrial estate case study — allocating solar generation to individual tenant sub-meters and billing at a discount to grid rate. ## Tenant Occupier Benefits Retail tenants benefit from: - **Discounted electricity**: Typically 15-22% below grid rate via landlord allocation - **EV charging for staff**: Staff who commute by EV can charge during shifts - **Sustainability reporting data**: MCS-certified solar generation data feeds directly into Scope 2 emissions calculations for tenant sustainability reports - **Covered car park**: Canopy structures add customer comfort and improve all-weather accessibility ## BREEAM In-Use Improvement Many retail parks seek BREEAM In-Use certification (or upgrading from existing ratings) as part of refinancing or sale preparation. Solar canopies directly contribute to: - **ENE 01**: Energy use and CO2 emissions — significant credit potential - **TRA 01**: Sustainable transport — EV charging credits - **MAN 01**: Sustainable procurement — local energy generation A 500 kWp canopy on a retail park can improve BREEAM In-Use score by 3-5 credits, potentially moving a park from Pass to Good or Good to Very Good. This has measurable impact on asset valuation. ## Sizing Retail Park Solar Canopies | Car park size | Suggested canopy | Annual generation | Annual saving | Payback | |---|---|---|---|---| | 200 spaces | 300 kWp | 312,000 kWh | £68,600 | 4.1 yrs | | 500 spaces | 750 kWp | 780,000 kWh | £171,600 | 3.7 yrs | | 1,000 spaces | 1,500 kWp | 1,560,000 kWh | £343,200 | 3.4 yrs | *Based on Midlands irradiance, 23p/kWh blended rate, 85% self-consumption.*
