The Structural Solution
UL 508 Controller
The Axone Single-Axis Tracker was designed to be durable, low-maintenance, and easy
to build in the field. The optimized single module in portrait row configuration keeps
material costs low as forces are minimized compared to other trackers with larger
surface area wings. Engineering on the generous 21kg/ module (less foundations) hot
dip galvanized steel sub-structure is based on the code prescribed velocities of ASCE
7-05 and does not factor ultra-light wind tunnel pressures. This approach to design
enables the baseline product to meet IBC 90mph (3-second gust) at full 45 degree tilt
without relying on the built-in stow feature. Perimeter wind shield torque tubes also
enable higher energy production and steadier uptime at typical sites that regularly
experience 30-40mph wind loads.
The state-of-the-art UL 508 listed controller has been designed with off the shelf Siemens components and is paired with
every single motor. This redundancy and direct control is essential to maximizing power plant uptime. We are also offering PV
Performance Controls™, a full SCADA platform which further enhances site management.

Design Approach
Bolted splice connections provide generous construction tolerances while also eliminating the need for field welding. With
a linear, pendulum style driveline and just 2 to 3 centrally located motors per MWp to lubricate, annual motor operation and
maintenance costs are virtually eliminated. Pre-assembled articulating gimbal post head assemblies with self-lubricating,
UV protected UHMWPE bearings allow for grade and foundation plumb tolerance, as well as long term serviceability. Direct
module attachment to rigid steel panel rails eliminate vibratory/thermal expansion and over-torqueing risks associated with
aluminum sandwich clamps.
