Custom-Engineered Solar PV for Retail Store & Showroom
As the world’s largest furniture and home goods retailer, IKEA operates on a global scale with a commitment to sustainability.
Project Challenges
The project involved expanding an existing 1,000kW solar PV system with a new 1,190kW addition. A primary technical challenge was the design and installation of the new array on the building’s flat roof. To maintain the long-term integrity of the roof and avoid any risk of leaks or structural damage, IKEA mandated a strict no-penetration policy. This required a completely custom solution that could support the extensive weight and wind loads of the system without compromising the roof’s waterproofing. Standard mounting systems were not an option, demanding a highly innovative and tailored approach.
Our Solution
Our engineering team, in close collaboration with our suppliers, designed and developed a custom, non-penetrating mounting bracket, which is the first-of-its-kind solution specifically for this project. This innovative bracket was engineered to distribute the system’s load safely across the flat roof without any penetrations. Through this custom solution, we successfully deployed the additional 1,190kW system, helping IKEA Canberra move significantly closer to its 2030 net-zero targets and demonstrating NGG’s ability to deliver large-scale, complex projects with bespoke solutions and an unwavering commitment to quality.
