The invention discloses a floating solar system. The floating solar system comprises a suspension device, a bracket and a solar panel; the suspension device is a prefabricated light-weight composite material foam body; the prefabricated light-weight composite material foam body and the bottom of the bracket are connected through a full-tread FRP rebar; and the top of the bracket and the bottom surface of the solar panel are connected through a connecting part. The floating solar system disclosed by the invention has the characteristics of being low in cost, excellent in durability, high in buoyancy, rapid to install, and convenient to perform batch production and construction; the engineering construction period and the cost of a floating solar photovoltaic power generation system can be effectively reduced; and thus, the floating solar system has obvious economical efficiency.
