Abstract
A tracking method and apparatus, an electronic device, and a storage medium. The tracking method comprises: in a solar tracking phase, determining a current weather type according to current weather data and/or current power generation of components on at least two photovoltaic tracking brackets (S110); and determining first target tracking angles of the components according to the current weather type, so that a tracking controller corresponding to the components adjusts the corresponding photovoltaic tracking brackets according to the first target tracking angles, so as to adjust the components on the photovoltaic tracking brackets (S120).
