Systems and methods for self-cleaning a surface of an object where an electrodynamic shield is mounted to the surface. The electrodynamic shield includes one or more sets of electrodes atop a substrate, at least one or more sets of electrodes being covered in a protective film. A coating is applied to the top surface of the protection film. A signal pulse generator is connected to the one or more sets of electrodes, and generates a pulse signal that causes the one or more sets of electrodes to generate an electric field. The pulse signal comprises a plurality of different pulse signals which have phase differences between consecutive signals, and the electric field causes a particle atop the coating to experience an electrostatic force and be repelled away from the coating. These pulse signals can be tuned to increase efficiency of removal depending on dust type and relative humidity.
