Angle irons as a core component

It’s said to impose considerably less loading on the roof than conventional module stands, thanks to its aerodynamic form. The company says it needs at most 50 percent of the ballast required by a conventional flat roof stand. The backs of the modules are lined with a metal sheet that reduces both dynamic pressure and prevents wind-pressure loads on the underside of the modules.

The core component of the supporting framework, however, is the newly developed TS-F angle iron. The module is fastened with it to the transverse sub-profiles and to the vertical supporting profiles at the back. This angle eliminates an oblique profile, thus saving on material cost. Instead, the module is screwed directly to the securing holes.

The solar modules are set up on stands at an angle of 20 degrees, reducing shadow intervals. The system is designed for modules with an output of 230 to 240 watts and 180 to 190 watts, since these have almost the same dimensions and the required metal back sheets are tailored to this size. The client thus needs no expensive custom-built items.
