GameChange Solar Leads the Way in Seismic Safety Testing

In a groundbreaking achievement, GameChange Solar has announced the successful completion of the industry's first full-scale seismic testing of single-axis solar trackers. This testing was carried out on their Genius Tracker system at the prestigious UC Berkeley's Pacific Earthquake Engineering Research (PEER) Center. The tests were designed according to IEEE 693 seismic design standards, simulating harsh earthquake conditions that are representative of high-risk regions like the New Madrid Seismic Zone.

Why Seismic Testing Matters

As solar energy expands into regions that are prone to earthquakes, understanding how solar technology performs under these conditions is crucial. Until now, the solar industry lacked substantial real-world data to gauge how utility-scale trackers and modules respond during seismic events. Scott Van Pelt, Chief Engineer at GameChange Solar, emphasized the significance of their testing by stating, "This test changes that. We now have conclusive evidence that a solar tracking system can be designed to withstand the forces associated with a meaningful earthquake."

The seismic shake table testing involved a full-scale tracker system that was subjected to intensifying levels of seismic inputs, including high-performance-level testing that simulated up to 2.5g spectral acceleration. The outcomes were promising:

1. Unyielding Structural Integrity: There was no structural damage to key components of the tracker such as torque tubes, bearings, posts, and actuators.
2. Effective Load Redistribution: GameChange's proprietary Lateral Capture System engaged as intended, effectively redistributing loads during the intense shaking.
3. Minimal Degradation: The tests showed no microcracking or significant power loss in the photovoltaic (PV) modules, with degradation remaining under 1%.
4. Operational Continuity: The tracker motor maintained full functionality even after undergoing the rigorous test.

Data Report and Future Implications

The results of these tests are detailed in a white paper titled "Seismic Shake Table Testing of Single Axis Solar Trackers," which can be requested from GameChange Solar's website. Additionally, this testing was featured in a recent pv magazine webinar, where experts discussed the implications of these findings.

A seismic failure at a solar installation can lead to extensive module damage, costly repairs, and prolonged energy generation downtime, severely impacting operations and safety. By establishing a performance baseline through these rigorous tests, GameChange Solar equips project developers, asset owners, and insurers with the necessary data to make informed decisions about seismic risks.

Furthermore, independent validation by the Renewable Energy Test Center (RETC) in Fremont, CA, corroborated that the Genius Tracker system remained in excellent physical and operating condition post-testing.
