Wind design is an important aspect for structural efficiency to help minimize cost and maximize the long-term reliability of any PV installation. Over the last several years, prescriptive load methodologies have arisen for the static wind loads of rooftop PV systems and ground-mounted PV systems. However, these prescriptive load methodologies assume that the PV structure does not move in the wind. Movement of flexible structures in the wind can lead to additional loads or in some cases can lead to wind-induced divergent motion causing structural failures. These failures have led to substantial economic losses due to downtime of the PV installations affected and to significant costs for retrofits and improvements to existing sites.
