PV Balance of System Award
Exotrack HZ increases system output up to 25 percent verses fi xed-tilt systems and is designed to mitigate maintenance costs for at least 25 years.
The technology features an east-west tracking range of ±50 degrees and a tracking precision of 1 degree.
Horizontal Single-A xis Solar Tracker Exotrack HZ
EXOSUN’S EXOTRACK HZ is a horizontal single-axis tracker for utility-scale PV applications.
Exotrack HZ boosts system output by as much as 25 percent in comparison to fi xed-tilt systems and its unique design mitigates maintenance costs for 25 years at minimum.
Solar trackers are an increasingly popular balance of system component installed to optimize yield in utility-scale systems. Exosun’s Exotrack HZ is a horizontal single-axis tracker for utility-scale PV applications that offers customers a more cost-effective and reliable tracking solution than competing technologies.
Operators can further optimize Exotrack HZ-equipped systems by implementing Exosun’s proprietary backtracking algorithm to drive the tables’ positions in order to avoid panel on panel shading during periods of low solar height - early morning and late afternoon - thus limiting power production loss.

At the heart of the Exotrack HZ is the Exobox a centralized monitoring and control system that supports up to 4 MW of trackers per unit.
The Exotrack HZ includes a patented individual backtracking program called SMARTracking™ which limits the impact of panel on panel shading on the plant’s yield. As a result an additional 5 percent output can be gained in comparison to other traditional single-axis trackers.

Module-Level Optimization byPower Optimizers
MODULE-LEVEL optimization of DC solar power harvesting is an innovative concept developed by SolarEdge which leads this market segment with 70% market share. The SolarEdge topology separates the two functions traditionally managed by the solar inverter so that DC/AC conversion is still carried out in the string level keeping system costs low while Maximum Power Point Tracking (MPPT is handled on the module level by power optimizers guaranteeing maximum power production from each module individually.
Power optimizers eliminate all power
