Revolutionary tracking system designed to lower lifetime costs and deliver measurable value to solar power plant owners;
Flexibly linked row design, with each industrial-grade motor driving up to 1MW, effectively reduces the number of potential failure points to a minimum and allows quality sourcing of key components for long-term reliability;
Ease of installation and significant upfront cost savings through Array’s single-bolt module clamp, material kitting, pre-assembled components, and relaxed installation tolerances;
Zero scheduled maintenance for 30 years. The DuraTrack HZ v3 drivetrain is lubricated and sealed for life. Array Technologies designs for the full site- specific wind load at full tilt angle without relying on active wind stow or UPS. v3 features a fully integrated, fully automatic wind load mitigation system which mechanically responds to loads on a row-per-row basis, improving tracker performance.
