A Roof Built for the Job
Cribbs Causeway is one of the largest retail destinations in the South West, on the northern edge of Bristol. The B&Q store there has the profile common to big-box retail: a very large, largely flat, largely unobstructed roof above a building lit and heated through every trading hour.
That combination is close to ideal. Few roof lights or plant to design around, a clear structural grid, and a consumption pattern that peaks during exactly the hours the array generates. Most of what is produced is consumed on site.
With Kingspan and Medas Construction we delivered 350kWp across the roof, with the store trading normally throughout.
Retail Warehouse Installation
350kWp delivered above a trading DIY superstore.
350kWp Array
Installation of 350kWp of photovoltaics across the retail warehouse roof, integrated with the Kingspan system.
Structural Assessment
Roof capacity assessed and mounting specified for the building’s structural grid.
Electrical Design & Connection
DC string design, inverter arrangement, protection and DNO notification.
Trading Continuity
Delivered without closing the store or restricting customer access.
The Cribbs Causeway Installation

What B&Q Got
350kWp On the Roof
Substantial generation above a store consuming heavily on lighting, heating and ventilation.
High Self-Consumption
Retail load profiles absorb most midday generation, maximising the value of every unit produced.
No Lost Trading
Installed above an open store with no interruption to customers or deliveries.
MCS Certified
Commissioned and certified under MCS with full electrical documentation.
Big-Box Retail Solar Across the UK
Alongside B&Q we have delivered solar for Sainsbury’s, Tesco, Aldi, Primark, NEXT and Lok’nStore — retail and distribution buildings from Bristol to Sunderland.
Retail parks and trade counters across Chester, Broughton, Wrexham and Deeside have exactly the same roof profile. If you operate a large-format retail or trade building in North Wales or Cheshire, the economics that worked at Cribbs Causeway will very likely work on your roof too.
Whatever your building type, we survey it, design for it and certify it. Talk to us about commercial solar panel installation, or browse the full solar portfolio.
