The already established long rail system Compactmetal TR for roof-mounted PV modules redirects all compressive and tensile forces through the sandwich panels into the building structure, so they are neither compressed nor damaged. These properties are also completely transferable onto the Compactwall TR system for solar facades.
Distributing loads intelligently
“Sandwich panels are not designed for additional loads, and the installation of PV modules can lead to distortion and damage,” explains Albert Vonbun, Aerocompact's Head of Product Management.

Aerocompact uses its established Compactmetal TR system for the facade solution. The extremely stable rails transfer the loads created by wind, suction and pressure forces via the screw heads of the sandwich fasteners and thus into the wall stanchions. These can be made of either wood or steel. Therefore, the thin sheet screws absorb the shear forces, the sandwich drilling screw transfers the wind loads directly into the building structure.
Thanks to the force transmission via the rails, users have the free choice of modules, regardless of the span width. The raised rail design ensures optimum rear ventilation of the PV modules.
