Abstract: The present invention relates to a solar electric roller shade, including a roller shade body and a solar panel that are independent of each other. The roller shade body includes a scroll, a curtain cloth wound onto the scroll, and a speed reduction motor for driving the scroll to rotate, the solar panel is externally disposed on a back surface of the roller shade body through a fixed support member, and the solar panel is electrically connected to the speed reduction motor and a battery. In the present invention, the solar panel and the roller shade body are two separated independent structures. Once mounted and debugged, the solar panel can continuously absorb light energy and provide electric energy for the electric roller shade under sufficient sunlight, and the solar panel is mounted on the back surface of the roller shade body without occupying a special erection space.
