Abstract：The east-west slope in the mountainous area will cause the east-west tilt of the adjustable photovoltaic supportcomponent after instalation，resulting in the lossof component power generation.In this paper，taking the automatic adjustable photovoltaic bracket as anexample，basedon the meteorological data of Yajiang County in Sichuan Province inthe past one year，thereal-time solar radiation analysis and calculation arecarriedout.Basedon this，the corresponding relationship between different east-west slopes and the theoretical power generationof photovoltaic modules is calculated. Combined with the topographic data of a large-scale photovoltaic power station in Yajiang County，thetheoretical power generationlossvalueof the power station due totheeast-west slope is estimated.Thecalculation results showthatthe greatertheslopeof the east-west direction，the greater the theoretical power generation loss ofthe component;under the same inclination angle，the power generation loss of the west slope is larger thanthatof theeast slope;inaddition，thesmal-angle eastern slope in western Sichuan contributes to he increase of power generation.
