Patent ID: 8921682

Claim:
A photovoltaic system able to float on water and track the sun, comprising a floating mechanism configured to float on water and comprising a chamber and four sleeves, each sleeve respectively arranged at one of four corners of the floating mechanism, wherein the chamber is configured to be partially flooded as ballast and buoyantly supported by the water; an adjusting mechanism comprising: a control unit, a valve connected to the control unit and communicating with the chamber wherein the control unit selectively operates the valve to admit a selected amount of water to enter the chamber as ballast to achieve a desired buoyant elevation of the photovoltaic system and stabilize the floating mechanism parallel to a surface of the water, four buoys, each buoy arranged in a respective one of the sleeves, and four pumps with a respective pump in fluid communication with a respective each one of the sleeves and the buoys such that an amount of water ballast in each buoy can be selectively adjusted so as to change the buoyant support height of each buoy with respect to a corresponding corner of the floating mechanism and adjust a tilt angle of the adjusting mechanism with respect to the floating mechanism and the surface of the water; and a solar power mechanism located above the floating mechanism and mounted on the four buoys such that the solar power mechanism also tilts to the adjusted tilt angle with respect to the surface of the water and the floating mechanism.
