A photoelectric power supply system for motorized window coverings includes a light detector electrically connected to a relatively high dielectric capacitor. In turn, the capacitor is connected to an electric motor, and the capacitor is the primary source of power for the motor. The light detector converts solar energy to electric energy that is used to charge the capacitor. The electric motor utilizes electricity from the capacitor as needed.
