Bidirectional single-layer cable net structure offshore photovoltaic supporting system

The invention provides a bidirectional single-layer cable net structure offshore photovoltaic supporting system, which comprises support piles for supporting a cable net structure and an anchoring structure for connecting the support piles at the periphery, and is characterized in that photovoltaic modules are arranged on the cable net structure, and connecting pieces are arranged at corresponding positions in a connecting manner; connecting and arranging steel beams among the pile tops of the support piles which are arranged and distributed; the cable net structure comprises assembly cables connected with the steel beams in the longitudinal direction and stabilizing cables connected with the steel beams in the transverse direction, and prestressed anchoring supports connected with the cable net structure are arranged on the steel beams on the periphery of the offshore photovoltaic supporting system. According to the invention, the whole photovoltaic module system is stable in plane and small in deformation t
