The present invention relates to a photovoltaic power-generating apparatus. The photovoltaic power-generating apparatus according to the present invention comprises: a solar cell module which collects solar light and converts the collected solar light into electrical energy; a frame including 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 hollow support frame which interconnects the upper frame and the lower frame and includes a plurality of support frames spaced apart from each other, wherein the frame enables the solar cell module to be outwardly exposed from the surface of water; a fluid delivery unit which moves the fluid from the interior of one of the support frames to the interior of another support frame such that the center of gravity of the frame changes on the water surface and the posture of the frame changes; and a control unit which analyzes changes in the azimuth angle of solar light, and controls the fluid delivery unit in accordance with the data obtained from the analysis, such that support frames are in communication with each other or closed to each other in order to change the center of gravity of the frame. |
