Sigma II

The perfect mounting system for major photovoltaic projects


Sigma II

The Sigma II system combines the installation advantages with the cost advantages of steel components. The galvanized mounting system stands out due to its simple, functional design. By using the proven Clickstone-technology, installation efforts are significantly reduced. Cap profile posts contribute to a higher load-bearing capacity and stability while reducing material requirements.

As a dual post mounting system, the Sigma II is perfectly suited for flexible module configurations. Depending on the project requirements, it can be installed using various foundations such as, ramming posts, earth screws or foot plates for concrete. An adjustable connection between the rafter and module rail enables installation on terrains with East/West slopes.


The system is developed and produced under certified sustainability standards. In addition, the components are recycable and easily disassembled.
