Abstract

For the economical and energy-efficient use of a PV system having upright, in particular bifacial, PV modules and to substantially avoid shading of the PV modules, a supporting structure which is simple to manufacture and install is provided, that is constructed by vertical posts, which are connected to one another at intersecting points, and horizontally running cross-members such that rectangular mounting areas are provided for the individual PV modules. The posts and cross-members are formed in a material-saving manner by conventional profiles, and a division of the posts into two interconnectable sections substantially facilitates the assembly. An electrical connection is provided such that active surfaces which are arranged one above another can be operated at different electrical operating points and such that electrical lines are formed which are operated separately from one another and are arranged in a horizontally running manner. This minimizes effects of shading of PV modules on the efficiency of the energy conversion.
