Several studies have shown that certain wind-design code standards applied to solar trackers are insufficient to design these structures reliably, as they do not consider the second order effects produced by the action of wind on the tracker. In order to prevent related structural instability issues, it is necessary to find new analysis methodologies that improve the design of reliable tracker structures by quantifying their response to the second order effects of the wind. The wind consultant leader RWDI in collaboration with Soltec has developed an innovative method, Dy-WIND for comprehensive dynamic analysis in tracker array wind design. With 15 years specialist experience, Soltec has incorporated this method in the design of Soltec trackers.
When designing solar trackers, several factors influence their response to the dynamic effects of the wind:
