Solar racking for PV modules on metal roofs

The AEROCOMPACTCompactMETAL are specially selected and designed products, suitable for all metal roof types. The corresponding module clamps are available in the click-on version for faster assembly. The clamps are available with and without earthing pins.

CompactMETAL TR Sandwich PV read more

The patented CompactMETAL TR system is a self-supporting long rail PV substructure for sandwich sheet metal roofs. The innovative fastening concept for the safe introduction of forces into the substructure is recommended by well-known sandwich panel manufacturers. The protected static algorithm in the AeroTOOL prevents the sandwich covering from being overloaded - even with the highest snow loads.

The Challenge

A common way of attaching PV systems to sandwich panels is to screw the substructure directly onto the top layer of the panels with thin sheet metal screws. The interaction of forces caused by snow and wind can in the long run lead to permanent damage to the upper level.

The result is leakage, detachment of the outer shell and the resulting “static uncertainty”. Sandwich panel manufacturers report
of extensive damage to building roofs.

The Solution

AEROCOMPACT® has developed a revolutionary fastening solution for PV modules on sandwich sheet metal roofs. By using innovative and patented components from the CompactMETAL modular system, the panels are only activated up to their permitted load limit.

The main role in the system is assumed by the TR long rail, which can assume loads over large distances. Wind loads are only absorbed via the sandwich fasteners and the rail. Snow loads are introduced directly into the substructure using a patented support concept. A patented structural algorithm regulates the maximum permissible bearing load for the intermediate bearings.

Intermediate support positions are statically determined and prevent the rail from touching the roof. This prevents damage to the panel. Self-tapping screws make assembly quick, easy and efficient. The clearly structured concept of the system is easy to understand and assembly errors are therefore minimized. Only self-tapping screws are used.
