Enhanced range of operation

maximum functionality
minimum hassle

Single-Axis-Tracking combined with intelligent adaptive backtracking guarantees reliable operation of the PV system to maximise energy yield.

The integration of enhanced sensor technology enables continuous condition monitoring and optimized operation based on actual wind speed, snow height, motor torque and inclination differences.

First time in late 2016 Mounting Systems GmbH requested Fichtner Group for an independent technical due diligence of its Sigma Tracker system. The assessment has been updated and complemented by Fichtner Group last time in 2020. It included the evaluation of design and design tools, the entire development process, functionality and static as well as processes to determine materials and dimensions in the framework of a sample project.

The Fichtner Report summarizes the findings as:

“In general and subject project adaptation, the Mounting Systems Sigma Tracker - bifacial system is of good quality and is stable compared to other tracker solutions since every rafter is supported and held in place by the adjustment devices. The system was developed within comprehensive procedures and tested in real life to proof reliability of the Sigma Tracker.“

Adapts to your needs

maximum flexibility
minimum complexity

The flexible configuration with up to three modules in portrait distinguishes the Sigma Tracker from many other systems.
The basic usability for bifacial applications without additional costs is also an essential part of the system flexibility.

Compliance with the standard warranty conditions of all module manufacturers with regard to the mounting of PV modules is fully guaranteed with the Sigma Tracker without any restrictions on functionality.

System integration

maximum availability
minimum interruption

Sigma Control® - the decentralized control unit allows control for each individual tracker and ensures maximum flexibility in planning, operation and maintenance.

Sigma View® - the unique operations management platform, connected via proven industrial network architecture from the market leader for automation technology, enables the seamless integration of the Sigma tracker into every SCADA system.

Low maintenance

maximum durability
minimum maintenance

The system’s profiles are manufactured from durable materials to ensure unlimited functionality and operational availability of the system even in highly corrosive environmental conditions.

Movement-relevant components are of course pre-assembled and checked in-house and delivered fully operational.

All electrical components and moving parts are designed to withstand extreme weather and environmental conditions and reduce interventions during normal operation to a minimum.
