Stable, bolted, durable mounting systems
The advantages of installation with hanger bolts/solar fasteners:
- Direct installation on the roof substructure means there is no load on the roofing
- Height-adjustable brackets enable level module installation
- The roof membrane is sealed by means of precisely fitting calottes or EPDM gaskets
- Good rear ventilation
- We will gladly create the structural design for our customer's projects if required – the documentation we provide includes the structural analysis as well as the installation plan for all components
Components
Hanger bolts and solar fasteners
Mounted with brackets for a stable screw connection with height adjustment.
Mounting rails
For end and centre attachment, S:FLEX systems rely on particularly lightweight, structurally optimised hollow chamber rails in various profiles and lengths that feature our proven one-click technology.
Connectors
To ensure structurally identical properties in the area of the rails and the connectors.
End and mid clamps
S:FLEX module clamps have an extremely wide clamping area and are therefore suitable for all standard modules and frame heights of 30-50mm. High torsion resistance and our latest, ultra-smooth one-click technology make installation a snap.

Our solid sloping-roof frame
This type of attachment is not only extremely stable, durable, weather and ammonia-resistant – the very good rear ventilation also helps to achieve a high degree of system efficiency.
