The wind effects on a ground-mounted solar panel under the influence of the panel tilt angles and wind directions were investigated; both experimentally and numerically. The ground-mounted solar panel was used with tilt angles of 25° and 45° for a Reynolds number of 6.4 ​× ​10⁴. Wind directions were varied from 0° to 180° at 30° intervals. A constant-temperature hot wire anemometer and a pressure scanner system were used to measure velocity and turbulence intensities and static pressure, respectively, in the wind tunnel. Numerical analyses were carried out via computational fluid dynamics methodology using the realizable k-ε turbulence model. The results showed that the flow structure had been significantly affected by the wind directions and panel tilt angles. The higher panel tilt angle caused stronger vortex shedding fluctuations, and higher velocity zones shedding frequencies. As with the flow structure, the design-relevant wind loads on the solar panel were also shown to be dependent on the wind direction and panel angle. The net pressure coefficients of the solar panel increased with the higher panel tilt angle. The critical wind directions were obtained as 30⁰ and 150⁰ in terms of overturning moments, while 180⁰ and 0⁰ wind directions were critical in terms of uplift and drag, respectively. The numerical results of the wind loads showed a good agreement with the experimental results.

研究了太阳能电池板倾斜角和风向对地面安装太阳能电池板的风影响；无论是实验上还是数值上。地面安装的太阳能电池板的倾斜角度为25°和45°，雷诺数为6.4×10 ⁴。风向以30°的间隔从0°更改为180°。使用恒温热线风速计和压力扫描仪系统分别测量风洞中的速度和湍流强度以及静压力。使用可实现的k-ε湍流模型，通过计算流体动力学方法进行了数值分析。结果表明，流动结构受到风向和面板倾斜角的显着影响。较高的面板倾斜角导致更强的涡旋脱落波动，以及更高的速度带脱落频率。与流动结构一样，太阳能面板上与设计相关的风荷载也显示为取决于风向和面板角度。太阳能电池板的净压力系数随着电池板倾斜角的增加而增加。倾覆力矩为⁰和150 ⁰，而风向分别为180 ⁰和0 ⁰对于升力和阻力至关重要。风荷载的数值结果与实验结果吻合良好。
