Due to its low damping, limited structural stiffness, and complex dynamic behavior, the flexible photovoltaic (PV) bracket is prone to significant wind-induced vibrations. The aeroelastic model can capture the multi-modal coupling effects in wind-induced vibrations of flexible structures.
An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted. The results indicated that the mid-span displacements and the axial forces in the wind-resistant cables are greater under wind-pressure conditions compared to wind-suction conditions.
Analyzing the aerodynamic loads on both solar panels and their support structures is crucial in the operation of a PV system. However, there is limited research on the wind-induced response of flexible cable-supported photovoltaic systems, with a notable lack of quantitative assessment of wind vibration responses.
