PURPOSE: A buoy for a solar cell is provided to prevent the drifting or shaking of a solar bell installed on the water, thereby achieving the optimum solar generation efficiency. CONSTITUTION: A buoy for a solar cell comprises a deck(101), protrusions(102,103), a winch, a control panel, loops, and a sun tracking unit. The deck mounts a solar cell. The protrusions are formed on one side in the longitudinal direction of the deck in order to minimize resistance against water current. The winch is formed in the protrusions in order to wind a wire connected to an outer fixing bar. The control panel determines the propagating direction of water current with reference to the tension applied to the wire and the sensing result of one of water current sensors and controls the winch so that the protrusions face in the direction of the water current. The loops are installed on the deck for fixing with adjacent decks. The solar tracking unit traces the direction of the sub and changes the direction of the solar cell. |
