One recommendation included wind load testing for ground-mounted solar arrays. Cyclic loading of dynamic wind loads caused considerable damage to the ground-mounted arrays. A second recommendation is an addition to ASCE 7-22 to account for the design criteria of ground-mounted solar arrays.
Cyclic loading of dynamic wind loads caused considerable damage to the ground-mounted arrays. A second recommendation is an addition to ASCE 7-22 to account for the design criteria of ground-mounted solar arrays. This could assist with the consistency of design for ground-mounted solar panels .
PV panels are usually mounted on the ground, for large production of solar power. The concern about solar panels installation is their vulnerability to high-intensity winds. Design standards are still under development and the guidelines are not clearly defined.
The procedure for calculating wind loads on roof-mounted solar arrays cannot be applied to ground-mounted solar arrays. Roof-mounted solar arrays are exposed to different aerodynamic wind flows than ground-mounted solar arrays .
