Unlock the Full Potential of Your Solar Array
Discover the power of the SIGMA Independent Tracking System® (ITS), an integrated solution for professional installers and plant operators. Developed by Sat Control, this universal solution offers unparalleled control and monitoring of dual- and single-axis solar tracking systems. It is engineered to deliver extreme precision and complete supervision for photovoltaic (PV), concentrated solar power (CSP), and heliostat plants.

Precision Engineering, Seamless Integration
The SIGMA ITS controls the movement of the tracking system in both elevation and azimuthal directions, making it suitable for a wide range of applications. With a high precision of 0.1°, this system is equipped with advanced settings and smart functions to ensure the maximisation of the plant’s yield. The system is designed for fast and easy installation and is fully compatible with all major third-party components and applications. It seamlessly integrates into existing control room technology, supporting 1- and 2-axis trackers with standard communication protocols.
