At least two pairs (1a, 1b; 1a', 1b'; 1a", 1b") of a first and a second ground support (1a, 1b; 1a', 1 b'; 1a", 1b") each for mounting PV module units with framed or unframed photovoltaic modules are arranged in a row one after the other above ground and at an angle (a) relative thereto. A first connecting element (6a, 6b) for a support connecting means (7a, 7b; 21; 23) is provided on the top end of every first ground support (1a, 1a', 1a") and a second connecting element (6a', 6b') for the support connecting means is provided on the top end of every second ground support (1b, 1b', 1b"). The connecting elements are fastened to a cross-member (3). Every first ground support is connected to its two adjacent second ground supports via a support connecting means. All first connecting elements have a shorter height above ground than the second connecting elements. The invention provides a substructure for photovoltaic modules which is lightweight, easy to handle during mounting and saves material. |
