This study mainly discusses the structure of ground-mounted solar photovoltaic panels. Using experimental modal analysis, the modal parameters, including natural frequencies, damping ratios, and modal shapes of the actual structure, are obtained and compared with those obtained by finite element modal analysis. The analysis results are compared with each other as the basis for modal verification. We established the wind pressure coefficient based on wind tunnel tests and literature data and conducted wind tunnel tests to obtain wind pressure data. This data is applied to finite element analysis to study the stress distribution of solar structures under the influence of wind. According to the results of this study, when the wind speed is 40 m/sec, the maximum wind-induced stress of the solar structure is approximately 4.12 to 5.99 times that when the wind speed is 20 m/sec. In addition, ultimate testing has shown that the location of the maximum stress is related to the size and location of the supporting components. When subsequent extreme testing is performed, it is recommended to use at least a 2 × 2 configuration of the solar panel structures to effectively demonstrate the structural strength under wind-induced vibration.
