In view of the design status of photovoltaic bracket design with the assumption of east-west horizontal direction

this study adopted 3D3S analysis software and relied on a south China agro-optical complementary photovoltaic power generation project to establish 7 types of photovoltaic bracket models with different east-west slope.The stress ratio of the main load-bearing member of the photovoltaic bracket and the influence of the reaction force of the column bottom on the east-west slope are analyzed.The results show that the stress ratio of the main stress component of the photovoltaic bracket including columns

inclined beams and purlins

increases with the increase of the east-west slope

and the stress ratio of the inclined beam is the most sensitive to the east-west slope

followed by the column and the purlin.In addition

with the appearance of the east-west slope

the column

inclined beam and purlin gradually appear east-west deformation

and with the increase of the east-west slope

the deformation gradually increases.
