The invention discloses a sun orientation control method for a double-shaft solar panel driving mechanism. The method specifically comprises the following steps: S1, calculating an included angle AngleB between a sun vector # imgabs0 # under an orbital system and an orbital system XoOoZo surface, and calculating an included angle AngleA between the projection of # imgabs1 # on the orbital system XoOoZo surface and an orbital system-Zo axis; s2, the actual rotation angle SADAA of an A shaft in the double-shaft solar panel driving mechanism and the actual rotation angle SADAB of a B shaft in the double-shaft solar panel driving mechanism are collected; s3, defining a threshold change limit A of an A axis of the double-axis solar panel driving mechanism and a threshold change limit B of a B axis of the double-axis solar panel driving mechanism; s4, the working modes of the A axis of the double-axis solar panel driving mechanism are set as A axis capturing, A axis tracking and A axis maintaining; the working mode of the B shaft of the double-shaft solar panel driving mechanism is set to be B shaft capturing and B shaft maintaining; s5, the working mode of the A axis of the double-axis solar panel driving mechanism is determined according to the numerical relation of the AngleA, the SADAA and the limit A; and determining the working mode of the B axis of the double-axis solar panel driving mechanism according to the numerical relationship of the AngleB, the SADAB and the limit B.
