Holders
PV modules can be held at a single point or in a line, with visible or invisible mounting structures. Brackets and SSG systems used in
post-and-beam structures are examples of linear holders. In point holders, the modules are fastened with clips, rivets or screws. This creates a frameless all-glass façade.

In the Fischer mounting system, the PV modules are fastened using anchor technology. In this system, no mounting points are visible on the outside. One well-known project in which this module mounting technique was used is the in-façade
PV system of the Kriegerhornbahn top station.
