System Highlights

Photovoltaics on facades with sandwich panels:

Building facades with sandwich panels are a large field of application for vertical photovoltaic systems. This is a certified system for FischerTHERM Carrier® panels from Fischer Profil GmbH. It can also be used on MONTANATHERM panels. A large proportion of modern commercial and industrial buildings are nowadays built with this material. Thanks to thread-forming, self-sealing screws and InsertionRail insertion system for PV modules, installation happens at high speed.

Fast, secure fixing:

The CarrierRail is mounted with building authority-approved thin sheet metal screws that seal and are tried and tested in the roof area. The well-known MK2 rail channel and the additional components for module fixation use familiar K2 mounting principles.

Closed surface with insertion rails:

Silver or black InsertionRails provide an attractive overall appearance and stiffen the system. The PV modules can be installed quickly and securely on the façade with the InsertionRail. Despite the largely closed surface, enough gaps remain for rear ventilation.
