Mounting systems

Do you have a flat roof and are still looking for the right PV flat roof mounting system?
Our variants offer you a quick and compact solution for different flat roofs.

PV flat roof mounting system – Flat roof elevations

A photovoltaic system on flat roofs offers you the opportunity to make optimum use of free roof space and achieve the highest possible yield.
Thanks to the high degree of pre-assembly of PV flat roof mounting systems, the elevations can be installed quickly, easily and without penetration on flat roofs.

With flat roof solutions from photovoltaic systems, you not only generate electricity for your building, but also increase your energy efficiency by lowering the temperature inside the building.

Photovoltaic systems with flat roof mountings reduce direct solar radiation on the roof.

The areas of application for PV flat roof mounting systems are almost unlimited.
We have optimized our substructure for the various roof conditions.
For example

    Maximum utilization of the flat roof area and flexible alignment
    Simple installation and maintenance of the PV system and the flat roof elevation
    Maximum utilization of the roof area with uninterrupted surfaces
    Aerodynamically optimized design for minimal balancing of the PV flat roof mounting

    Our PV flat roof elevations

    With our various flat roof mounting systems, we cover all roof types and can guarantee the ideal application for you and your customers.
    With our PV flat roof mounting systems, we focus on optimized handling during installation and the integrity of the roof structure.

    Thanks to our design, you benefit from the low ballasting of the systems, making them ideal for roof load reserves on flat roofs such as gravel and green roofs.
    Furthermore, our systems and our spacers have been developed to provide an ideal solution for bitumen roofs and can be used universally.
