In recent years,the construction of photovoltaic power stations has been in full swing.The land resources with good terrain conditions in the plains have gradually diminished,and the proportion of mountain photovoltaic projects in new constructions has been on the rise.Taking a certain mountain photo-voltaic project in Honghe Prefecture in Yunnan province as an example,by establishing a three-dimension-al finite element model of mountain photovoltaic with different east-west slope degree,a comparative anal-ysis was conducted on stress and deformation of the main components of the photovoltaic bracket,and the following conclusions were reached:The east-west slope degree does not change the failure mode of the mountain photovoltaic bracket,but they affect the magnitudes of stress and deformation of its main com-ponents.When the east-west slope degree is greater,the stress concentration and deformation of the mountain photovoltaic under the same wind pressure is more severe,and the corresponding bearing capaci-ty is also lower.
