Substructure 

The sub-structure is the base for the in-roof installation of the modules. 
It consists of slats and mounting boards that are attached directly on the 
roof. It is created using the grid plan (see chapter

Mounting bracket 

The modules framed with SOLRIF® XL-profile frames are anchored 
with mounting brackets in the substructure. For this purpose, three dif-
ferent types of clamps can be used:
