The floating photovoltaic(FPV)technology in freshwater bodies has overcome some limitations of traditional land-based photovoltaics and experienced rapid development over the past decade.Meanwhile,applying FPV technology in marine environments has become an important proposition for scholars worldwide.Unlike land,the open expanse and extended sunlight duration in marine environments offer advantages such as higher solar radiation utilization efficiency,resulting in significantly increased power generation.However,ensuring the survival of offshore floating photovoltaic(OFPV)systems under extreme natural conditions poses the greatest challenge to their implementation in the future.This paper first outlines the development of FPV systems,analyzes various floating structures'forms,characteristics,and their suitability for marine environments.It then focuses on the hydrodynamic and structural integrity issues that different types of OFPV structures may encounter under wave and wind loads,reviewing research findings from scholars worldwide regarding the feasibility of such structures.Finally,potential future directions for OFPV systems are proposed.
