The nearshore floating photovoltaic (PV) power systems effectively address the contradiction between the need of PV power development and limited land resources
offering significant economic and social benefits. However
such systems are still in the early exploration stage and lack systematic research. This study utilizes PVsyst and SolarPV simulation software along with AQWA hydrodynamic simulation results to establish models of floating PV systems under various typical daily time scales in complicated nearshore environments. It comprehensively explored various key factors influencing system performance. A linear regression numerical model was developed based on simulation results
and path analysis was used to compare their impact on system performance gains. The results indicate that sea surface reflectance (37.9%) has the most significant impact on system performance
followed by average tilt angle during floating (30.6%)
installation tilt angle or front-to-rear spacing (17.5%)
