SUPPORT TRACKING METHOD AND SYSTEM, PHOTOVOLTAIC DEVICE, AND MEDIUM

A support tracking method and system, a photovoltaic device, and a medium. The support tracking method comprises: obtaining irradiation data of each target photovoltaic module (304) (S110); obtaining an initial tracking angle of each target photovoltaic module (304) (S120); adjusting the tracking angles of the target photovoltaic modules (304) according to the irradiation data and the initial tracking angles, and calculating total power generation capacities of the target photovoltaic modules (304) corresponding to different tracking angle adjustment modes (S130); and on the basis of the total power generation capacities of the target photovoltaic modules (304), determining a target tracking angle adjustment mode for the target photovoltaic modules (304) (S140). A micro-shielding model is built, the total power generation capacities of a photovoltaic module array after adjustment by using different tracking angle adjustment mode optimization combinations are calculated, and the target adjustment mode causing the optimal total power generation capacity is determined, such that the influence of a shielding or light leakage phenomenon occurring in an inverse tracking stage on the total power generation capacity of the photovoltaic module array is reduced, and the total power generation capacity of the photovoltaic module array is optimal.
