Passive mooring system enables floating PV to track water-level changes

Researchers from Morocco have developed a novel mooring system for floating PV systems that automatically adjusts to water-level changes, reducing platform motion without the need for active control or external energy. The system, based on a counterweight-and-pulley mechanism, showed significant reduction in horizontal displacement and achieved a high tracking efficiency of 75%. This passive mooring system offers a mechanically simple design for stable FPV installations in remote, low-maintenance environments. Future research will focus on scaling up, testing with real hydrodynamic loading, and field pilot deployment after the system's proof of concept was presented in a study published in Scientific Reports.
