4 Frequently Asked Questions about “Photovoltaic tracking bracket damage case - RRR Renewable Projects (SA)”
Are solar trackers causing structural damage?
The most important dynamic wind mechanisms that can endanger the structural health of solar trackers are resonant vibration and the torsional flutter or galloping, . The resonant vibration mechanism occurs when the solar tracker is excited at its natural frequencies.
What causes a catastrophic failure in a solar tracker?
A catastrophic failure in a solar tracker is analyzed in detail. The failure occurred under a high-speed wind dust and 0 deg tilt angle. Torsional galloping has turned out to be cause of the failure. A numerical FEM model is used to obtain the maximum stresses in the solar tracker.
What types of solar trackers are used in solar power plants?
Photovoltaic (PV) systems and specifically one-axis solar trackers are the most used type of installations in solar power plants. Those solar trackers are slender structures installed in open-air areas sometimes subjected to high speed winds.
Why did a solar tracker break?
The high plastic deformation in some parts of the structure lead to the PV modules to contact the ground and to break after that. The solar tracker was fixed at 0 degrees tilt angle at the moment of the accident, where the static wind forces are minimum.
