Sigma TR2

The Sophisticated Single-Axis Solar Tracking System for Extra-Large Bifacial PV Modules

For large solar parks and especially for AgriPV applications, our Sigma TR2 offers you an optimum cost-benefit ratio.

As the world's first tracking system, the Sigma TR2 offers a self-locking linear drive for each individual system post and is equipped exclusively with industrial standard components in the drive and control system.

The top-mounted and fully encapsulated drive system makes it safe to use in the Agri PV sector even without fencing.

  • Design principles

    We are happy to present our design principles to you in a transparent and comprehensible manner.

    On the basis of the Eurocodes and especially its National Annexes we provide you with systems that meet the requirements of wind, snow and earthquake loads as well as air and soil corrosivity.

    This enables us to provide a structural warranty for our systems for the entire planned operating lifetime.

  • PV modules

    Depending on the configuration requirements, the system is suitable for both portrait and landscape installation. With our Sigma Tracker, all currently common PV modules can be reliably clamped or screwed in accordance with the regulations of the OEM manufacturers.

  • Cable management

    The integrated cable management concept enables simple, yet protected (UV and mechanical) laying of cables within the longitudinal rails of the tracking system.

    As an option, we offer you the integration of string inverters or DC collectors within the Sigma Tracker.
