This study presents an experimental proof-of-concept for an innovative floating system designed to harness solar energy in coastal regions. The concept leverages the combination of two distinct elements: a double-axis solar tracker, maximizing solar energy generation, and a tension-leg platform (TLP), ensuring structural performance and stability. Tests on a 1:30 reduced scale model of the preliminary prototype were conducted in a wave tank, initially focusing on regular wave conditions. The outcomes are highly encouraging, with the motions of the platform remaining remarkably stable even during large amplitude waves. This stability is crucial, as it enables floating solar systems to minimize electricity generation losses caused by panel misalignments and ensures their resilience during extreme events.
