The solution that leaves no question unanswered: Maximum material efficiency, solidity and construction simplicity make the Sigma Tracker the most cost-effective solution for your PV project.
Thanks to our Desert Suitability Test and pre-assembled delivery, the Sigma Tracker guarantees a cost-efficient and quick setup under all weather conditions.
Good news for investors and operators: With a planned design lifetime of more than 25 years, the Sigma Tracker is optimized against wear and tear for operation in extreme climate zones. We guarantee the availability of our systems for your solar project.
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
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.

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.
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.
Which modules do you need in which orientation? We offer detailed engineering, including all static calculations (including corrosion, wind and snow load analysis). We measure, secure and test the stability of your entire system.
You will receive a detailed implementation plan defining all technical parameters such as distances and tolerances. Furthermore, we will provide you with recommendations for the type and dimensions of the foundations (concrete, screw, floating foundation, piles) as well as for operation and maintenance.
We will take your individual requests and all project-related factors associated with the local environment into account. This includes weather conditions such as prevailing winds and snowfall probability, and ground conditions such as terrain type and soil composition.
We guarantee express delivery directly from the manufacturer, provide delivery and repackaging services at the port, and take care of all your legal documents.
On site, we build your foundations (piles, concrete, gabions, pontoons) and assemble the entire system, including the installation of the solar modules and string inverters.
A project manager will be assigned as a permanent, personal contact, and under their direction, a construction site manager will take care of the complete logistics on site. Additionally, we offer installation training, coach your technical staff and define project-based control parameters for construction monitoring. The inspection and commissioning of our products complement and complete this crucial package of services.
Operation and Maintenance
Not just nuts and bolts, but peace of mind. Mounting Systems offers tailor-made service contracts with all the maintenance you need, including long-term availability guarantees. And if needed, we can also issue expert reports (TÜV CERT) and warranty extensions perfectly suited to your requirements.
