Norway’s Arctic Cold Store Installs 6,400 Vertical Solar Panels Held by Friction Alone
Oslo-based Over Easy Solar installed 6,400 vertical solar panels on the roof of Tromsøterminalen, a major Arctic cold store in Norway. The 320 kWp array uses no bolts or ballast, relying solely on friction and low wind lift to stay secure. This vertical orientation prevents snow accumulation, which typically renders flat panels ineffective in northern climates. The installation was completed by a three-person crew in four days, marking the world’s largest vertical rooftop solar system. While specific yield data from the new roof is pending, comparable research sites show a 54% performance advantage over conventional tilted arrays in high-latitude regions.
