To improve the utilization of solar irradiance by a bifacial photovoltaic (PV) flat single-axis tracking system under complex weather conditions, a dynamic optimization model for bifacial PV modules, a hybrid tracking algorithm was developed. Scattering coefficients are defined to differentiate weather conditions consistently so as to select different algorithms for tracking. The sun's position is tracked by using the visual sun trajectory model on sunny days, while the maximum sum of irradiance of bifacial modules is used as the tracking angle setting principle for high scattering weather.
