A solar bird repeller mainly comprises drivers and bird repelling bars, wherein the drivers and the bird repelling bars are arranged on different voltage-class overhead line pole towers; each driver comprises at least one solar generating panel fixed on a plastic cover; a brushless motor and a control circuit board are arranged in each plastic cover at least; each bird repelling bar consists of a main bird repelling bar and an auxiliary bird repelling bar which are connected with each other; a motor shaft of each brushless motor or a transmission shaft connected with the motor shaft is connected with one end of the corresponding main bird repelling bar in a nested and riveted manner; each auxiliary bird repelling bar is provided with a bell; each main bird repelling bar or each auxiliary bird repelling bar consists of a solid circular nylon bar; the other end of each main bird repelling bar is provided with a hole which is perpendicular to the extending direction; each auxiliary bird repelling bar which can flexibly slide in the corresponding hole penetrates in the corresponding hole; and two ends of each auxiliary bird repelling bar are respectively provided with bells. The solar bird repeller has the advantages that the solar bird repeller can stably run for a long time, is seldom affected by surrounding environments, and is high in corrosion resistance; a bird repelling effect is high; grounding and disconnection faults caused by various bird troubles can be effectively reduced; and the reliability on power supply is improved.
