20120152316 | TRACKING DEVICE FOR A PHOTOVOLTAIC SYSTEM, AND METHOD FOR INSTALLING SUCH A TRACKING DEVICE - A tracking device contains, for in each case one photovoltaic module, a supporting framework, which has a vertical tracking device and a horizontal tracking device which is forcibly mechanically coupled to the latter. The vertical tracking device contains a supporting structure, which is a supporting mast and is mounted in a rotatable manner about a vertical axis. In operation, vertical tracking is executed with the aid of an electromotive drive, the actuating movement of which is transmitted to the supporting structure. The horizontal tracking device contains in particular an elevation element, which defines a mechanical guide track having different height levels. In operation, the height levels defined by the guide track are transmitted to the photovoltaic module via a mechanical coupling device, in the event of a rotational movement of the supporting structure about the vertical axis, in order to create a pivoting movement about the horizontal axis. | 06-21-2012 |
