DuraTrack HZ v2.5
®
Array Technologies’ DuraTrack HZ single-axis horizontal solar
tracker optimally balances performance with high durability,
long-term reliability, and minimal operation and maintenance,
to maximize the ROI for utility-scale and commercial projects.

The constructability of the system is
a huge benefit to both the contractor
installing the system and ultimately
the project’s developer in terms of
labor cost and schedule savings.”
JASON LIVENGOOD & STEVE HOYE, JE DUNN CONSTRUCTION
Unlike “push-pull” tracker designs, DuraTrack HZ’s rotating gear-drive
system does not compound wind forces through the driveline, resulting
in an uncomplicated, robust solution that requires less structural
material and parts.

Articulating driveline connections accommodate installation on
undulating terrain and irregular site boundaries while immensely
relaxing installation tolerances, reducing the risk of installation errors
and increasing deployment speed.

Designed to expedite the development of large-scale solar plants, the
DuraTrack HZ high-density, low-profile system has less motors per MW
making it easier to install, operate and maintain.

Full-scale wind tunnel testing of the DuraTrack structure, and laboratory
lifetime-tested components, results in a reliable and durable system
that has proved to exceed expectations.
DuraTrack HZ v2.5
AJO , ARIZONA – 6 M W
There are many types of terrain that
present unique challenges for solar
installations, but one is particularly
common: sites that have uneven,
undulating topography that in many
cases requires extensive grading.
Array Technologies’ DuraTrack HZ
system utilizes a cutting-edge,
articulating driveline design that
enables installation on undulating
terrain, equipped with proprietary
joints that can move up to 40° off
angle while relaxing installation
tolerances. This completely
eliminates the need for extensive
earthworks at naturally undulating
sites such as this one in Arizona.
