A solar-powered transmission device includes a casing, a cover, a drive unit, and a solar collecting panel. The casing is formed with a hole unit. The cover cooperates with the casing so as to confine a component receiving space, and has a transparent portion that permits entry of light into the component receiving space. The drive unit is mounted in the component receiving space, and includes a motor, a speed-reduction gear set coupled to and driven rotatably by the motor, and an output shaft unit coupled to and driven rotatably by the speed-reduction gear set. The output shaft unit extends through the hole unit in the casing. The solar collecting panel is disposed in the component receiving space and is coupled electrically to the motor.
