Effect of Building Height on Wind Load Characteristics of Photovoltaic Arrays

The present study is carried out by FLUENT software, and the wind load characteristics of photovoltaic arrays installed on different building heights are analyzed. The analysis results show that the higher the building height, the larger the radius of the main vortex formed above the photovoltaic array. When H=0 m, the absolute value of the overturning moment coefficient of the photovoltaic array is much larger than those of the array installed on the roof, and it’s along the decreasing trend of the incoming flow. The shape coefficient of the photovoltaic array shows an obvious gradient change, and as the height of the building increases, the shape coefficient of the building also follows decreasing.
