SIGMA Independent Tracking System®

SIGMA ITS provides an integrated solution for EPCs and plant operators seeking greater tracking accuracy and seamless drive communications.

SIGMA independent solar tracking system (ITS) developed by Sat Control is the universal solution for control and monitoring of dual- and single-axis solar tracking systems.

It controls the movement of the tracking system in both elevation and azimuthal directions which makes it suitable for a wide range of applications. Sigma ITS delivers extreme precision and complete supervision of the trackers in photovoltaic (PV), concentrated solar power (CSP) and heliostat plants.
