GameChange Solar, a photo voltaic tracker and fixed-tilt racking know-how provider, accomplished of the business’s first full-scale seismic shake desk testing program for its Genius Tracker system at UC Berkeley’s Pacific Earthquake Engineering Analysis Middle. The testing was carried out in accordance with IEEE 693 seismic design requirements, simulating excessive earthquake situations.

A full-scale tracker system with mounted PV modules was subjected to more and more stronger seismic situations, and the system skilled no structural injury to key elements, together with torque tubes, bearings, posts, and actuators, and no microcracking or significant energy loss to modules. The tracker makes use of GameChange’s proprietary Lateral Seize System to redistribute hundreds from seismic forces throughout testing. And tracker motors continued working after the check. This was validated by third-party observer Renewable Power Check Middle in Fremont, California.
“As photo voltaic expands into seismic-risk areas like California, Chile and the New Madrid Fault Zone, the business has had negligible real-world knowledge on how trendy utility scale trackers and modules carry out in an earthquake,” mentioned Scott Van Pelt, chief engineer at GameChange Photo voltaic. “This check adjustments that. We now have conclusive proof {that a} photo voltaic monitoring system, similar to GameChange’s Genius Tracker, might be designed to face up to the forces related to a significant earthquake.”
GameChange covers the check leads to the white paper “Seismic Shake Table Testing of Single Axis Solar Trackers.” Seismic failures can have an effect on a tracker system’s producing capability and might pose security dangers O&M personnel.
