Two-axis tracking systems for photovoltaics have been known for many years to be far more productive than fixed panels or one-axis tracking systems.
But two-axis trackers have been considered less reliable than fixed racks or one-axis trackers.
InteliTrack systems have only two moving parts – actuators and bearings – and both have been proven reliable through extensive accelerated testing.
When compared with other components in your solar electric system, these simple components are extremely long-lived.
InteliTrack systems use actuators proven for many years in rugged, outdoor applications, such as John Deere farming equipment.
To evaluate their reliability for use in tracking systems, Sedona analyzed test data which showed expected life of more than 100 years.
The actuators used in InteliTrack systems were also subjected to a variety of environmental and electrical tests, under conditions summarized in this chart:
|Temperature||-40 C to +90C|
|Temperature change||-30 C to +100 C in less than 10 seconds|
|Heat and humidity||93% to 98%, -40 C to +55 C|
|Salt mist||5% NaCl, 500 hours exposure|
|Water ingression||Per IPX6|
|Salt water dunk||115 C for 20 hours; immersion in 20 C salt water|
|Free fall||0.4 m onto steel|
|Vibration||5 Hz to 200 Hz|
|Shock||100 g for 6 milliseconds|
|Electrical||Electrostatic discharge rf fields Fast transients Surge transients Magnetic fields|
The actuators performed well even under these extreme conditions.

InteliTrack systems use bearings made of high-density polymers, which are self-lubricating and require no maintenance. The materials chosen are resistant to ultraviolet radiation.
Accelerated aging tests show expected life over 100 years in this application.
- High-density polymer
- Resistant to corrosion
- Resistant to ultraviolet radiation
Every InteliTrack system is optimized for the site where it will be installed, to make sure it produces the maximum possible energy from each panel. You will see for yourself the simple, rugged construction of your system!
