The tracker, suited to utility-scale systems, was tested by the Canadian Standards Association (CSA) for reliability and durability. The Exotrack HZ system is designed to last 25 years and the company claims the tracker can deliver up to 25% better output efficiency than fixed-tilt systems.

Exosun also claims the Exotrack HZ, which has a centralised control system for its operation, is low maintenance. Underwriters’ Laboratories UL3703 certification is the horizontal axis tracker equivalent to the UL2703 certification given for fixed-tilt structures.

Exotrack HZ also underwent wind tunnel testing with CPP Engineering. The successful accreditation under the Underwriters’ Laboratories (UL) 3703 standards paves the way for the company to continue their North America expansion plans. The firm recently established a US office and local executive team.
