The European project SuRE (Sustainable, Reliable, and Efficient) has addressed key barriers in floating PV—sustainability, reliability and cost-efficiency. The project was led by a group including Fraunhofer Gesellschaft, focused on reducing environmental impact, managing end-of-life systems, and lowering power generation costs. Activities were structured into three areas to improve design, durability, and lifecycle performance. Ciel et Terre has tested a new floater at 50 kW, scaling to 5 MW. Zimmermann PV-Stahlbau has planned a 5 MW installation suited for high sea conditions. Sunlit Sea is scaling offshore FPV with a 100 kW pilot on Norway’s coast. The project has delivered measurable data, material innovations, and validated prototypes. SuRE has aligned with EU energy and climate goals, enabling scalable, low-impact floating PV deployment across inland and offshore European sites.
