Abstract: Class C geomorphology is simulated in the atmospheric boundary layer wind tunnel,and a rigid model pressure measurement test is carried out on the solar panel model of high-rise apartment’s balconies with a scale ratio of 1∶80. Firstly,a probabilistic analysis of extreme wind pressure coefficient for the panel is carried out. The results show that the selection of the probabilistic model of the panel extreme wind pressure coefficient is less affected by the panel position and the direction of incoming wind. The generalized extreme distribution can be used to describe the probabilistic model of the panel extreme wind pressure coefficient. Secondly,the effects of installation tilt angle,height,location of the panel,different factors on the extreme wind load characteristics for the solar panel are studied. The results showed that there are different wind load characteristics between top floor’s balcony solar panels and middle floors’ solar panels. The mechanism of wind load effect is obviously different from the balcony facade. The most adverse extreme wind pressure coefficient and the change of installation angle do not show a monotony relationship for the panel inclined to the balcony facade. Finally,the design value of the extreme wind pressure coefficient of the balcony solar panel is proposed based on the envelope method.
