<P>PROBLEM TO BE SOLVED: To provide a photovoltaic generation device, capable of securely preventing a break of a motive power transmission unit of a tracking device and a panel thereof with an automatically minimized wind receiving area such as a horizontal posture even at a blackout. <P>SOLUTION: A photovoltaic generation device S includes: a photovoltaic generation panel P having a condenser lens unit 1, disposed outside, with a plurality of dome Fresnel lenses (condenser lenses) 2 connected in series in both vertical and horizontal directions; a pole 20 for rotatably supporting the photovoltaic generation panel P along the orbit of the sun in a manner to tilt the photovoltaic generation panel P in the earth axis direction so that the photovoltaic generation panel P can track the sun; and motive power transmission units 22a, 22b, 26, 27 and 31 disposed on the top end portion of the pole 20 and including motors M1, M2 capable of tilting and revolving the photovoltaic generation panel P. When the motors M1, M2 stop at the blackout or due to a failure in an electric system, the photovoltaic generation panel P comes to have the horizontal posture by the tilt thereof along the earth axis direction by the self-weight (W). <P>COPYRIGHT: (C)2013,JPO&INPIT |
