A triangular support element with a pre-set module incline angle. Intended for ensuring the optimum incidence angles when setting up solar modules onto building roofs. Generally for a landscape layout of standard sized modules in a single row. The triangular support element is intended for mounting solar modules on flat roofs with up to 5° incline or roofs covered with sheet metal roof coverings, to which they are fastened simply by using suitable screws or weight elements. On trapezoidal sheet metal roof coverings, it also enables transversal support orientation appropriate for east-west roof ridge orientation. The use of additional fasteners is not needed. Suitable for greater loads (e.g. wind and snow).
