Embodiment Construction

[0041] figure 1 A photovoltaic system known from the prior art according to EP 1710651 B1 is shown, which has a two-axis tracking device. The photovoltaic system has a plurality of support frames 2 each supporting a photovoltaic module 4 . In this exemplary embodiment, two support frames 2 are shown as an example. Each photovoltaic module 4 is pivotable about a vertical axis 6 and about a horizontal pivot axis 8 . A common drive motor 10 is provided for joint adjustment and tracking, which transmits a positioning movement to the corresponding support frame 2 via a drive, which in this exemplary embodiment is at the end of a cable 12 form, so as to effectuate the synchronous rotation of these individual support frames 2 about their corresponding vertical tracking axes 6 . In the case of such vertical tracking, horizontal tracking about the pivot axis 8 is forced to take place simultaneously by means of a positive mechanical connection.

[0042] The support frame 2 is genera...

Abstract

In order to make it easy to install a tracking device for a photovoltaic system, in which a horizontal tracking device is positively coupled to a vertical tracking device by mechanical means, preferably two adjusting mechanisms are provided. One adjusting mechanism is used for rotationally moving an elevation element (22) about a vertical axis (6) relative to an anchoring element (14). The second adjusting mechanism is used for also rotationally moving two sections (36A, 36B) of a mast (16) about a vertical axis (6).

Description

technical field [0001] The invention relates to a tracking device for a photovoltaic system having the features stated in the preamble of claim 1 and a method for installing such a tracking device. [0002] Such a tracking device is known from EP 1710651 B1. Background technique [0003] In a photovoltaic system, the available energy yield depends on the angle of incidence of the sun relative to the photovoltaic modules, and therefore, in order to increase the energy yield, it is advisable to use means for the photovoltaic modules of the system to track the position of the sun, the sun The location is changed according to the time of year or time of day. In this context, first of all vertical tracking shall be mentioned, in which the photovoltaic modules are caused to track the path of the sun by rotating the support structure carrying the modules about an axis substantially vertical with respect to the earth's surface. Furthermore, in the case of biaxial tracking, horizon...
