PHOTOVOLTAIC POWER-GENERATING APPARATUS

The present invention relates to a photovoltaic power-generating apparatus. The photovoltaic power-generating apparatus according the present invention comprises: a solar cell module for collecting a solar light and converting the collected solar light into an electrical energy; a frame comprising an upper frame in which the solar cell module is installed, a lower frame spaced apart from the upper frame in the downward direction, and a support frame part which interconnects the upper frame and the lower frame and has a plurality of support frames spaced apart from each other, wherein the frame enables the solar cell module to be outwardly exposed from a surface of water; a fluid delivery unit which moves the fluid from an interior of one of the support frames to an interior of another support frame in such a manner that a center of gravity of the frame changes on the water surface and a posture of the frame changes; and a control unit which calculate the target posture of the frame for the given sun location, and controls the fluid delivery unit in accordance with a data obtained from the calculation, in such a manner that the support frames are in communication with each other or closed to each other in order to change the center of gravity of the frame.
