The construction systems for photovoltaic systems must be regulated in the building authority approval of the sandwich components. In contrast to trapezoidal profiles, sandwich elements are composite components for which all possible influencing variables are tested and regulated in the "Allgemeine bauaufsichtliche Zulassung" (abZ). Whether for existing or new buildings - the right system for you is part of our general building approval (abZ).
The age of the building and the associated approval of the elements determines which system can be used. The solar modules are installed parallel to the roof. Depending on the system, various rails and holders are installed, on which the PV modules are clamped. The connection to the sandwich elements can be made in different ways:
Load application directly into the substructure
Mounting on or at the high beads, in the upper shell
