Revolutionary mounting solution for sandwich roofs: AEROCOMPACT launches patented support system for PV installations

The Austrian expert in PV mounting solutions AEROCOMPACT has developed a new support system for solar energy systems on sandwich panels. The patented racking system is the first solution on the market that does not stress or damage the panels, because it transfers all compressive and tensile forces directly to the roof substructure. The heart of the racking solution of the COMPACT METAL modular system is the 5.8 meter long TR74 carrier rail, which has been available since August.

The Austrian expert in PV mounting solutions AEROCOMPACT has developed a new support system for solar energy systems on sandwich panels. The patented racking system is the first solution on the market that does not stress or damage the panels, because it transfers all compressive and tensile forces directly to the roof substructure. The heart of the racking solution of the COMPACT METAL modular system is the 5.8 meter long TR74 carrier rail, which has been available since August.

With its new racking solution, AEROCOMPACT has solved an industry-wide problem: until now, installers usually fasten PV systems to sandwich panels by screwing the substructure directly to the top layer of the panels with thin sheet metal screws. However, the interaction of forces caused by snow and wind can permanently damage the top layer in the long run, leading to leaks, detachment of the outer shell and a resulting “static ambiguity”. Manufacturers of sandwich panels report large-scale damage to roofs of buildings.

Thanks to the new AEROCOMPACT carrier system, the rail does not rest directly on the roof, but is directly connected to the underlying purlin with self-drilling carrier screws. The PV substructure is fully supported on it. Therefore, no compressive or tensile forces from wind or snow are introduced into the sandwich panels. “The span of the 5.8 meter long support rail is unique and the entry points can withstand very high forces,” explains Marco Rusch, Group Head of Corporate Communications at AEROCOMPACT.

Spacer sleeves and additional supports guarantee an even distance between the rail and the roof and thus ensure good ventilation at the rear. A pre-assembled rubber seal prevents moisture from entering the upright beads. A patented static algorithm controls the optimal distribution of the support points on the roof in the planning software AEROCOMPACT.

Panel manufacturers are excited

“Leading sandwich panel manufacturers are enthusiastic about our structural design,” Rusch is pleased to report. He explains: “Usually PV systems are mounted directly to the roof panels with sheet metal screws, which causes compressive and tensile forces to act on the panels and damage them. With our design, damage is almost impossible.”

For this reason, no approvals or additional checks from the manufacturers are required for the installation, which also makes the retrofitting of solar energy systems in particular much easier. For example, with the innovative mounting system, PV systems can even be installed on roofs where neither the condition nor the module manufacturer is known. “Since the roof substructure absorbs all forces, it is irrelevant which panels are installed and which forces they can withstand,” explains Rusch.

Plan load distribution

AEROCOMPACT has integrated the fastening solution – which is suitable for wooden, steel and aluminum purlins – into AEROTOOL, its internal planning tool. There, planners will find automatisms for optimum load distribution. The mounting system is approved by a federal certification institute. AEROCOMPACT comes with a 25-year warranty.


From Bangkok to New Orleans

AEROCOMPACT will exhibit the new support rail and other new products between September and November this year at the ASEAN Renewable Energy trade show in Bangkok, Intersolar Europe in Munich, Key Energy ITALY in Rimini, Renewable Energy India in Greater Noida, Solar Power International in New Orleans, Solar Solutions International in Haarlemmermeer and Solar & Storage Live in Birmingham.
