Abstract: System and method for identifying solar panels. In accordance with exemplary embodiments, an electrical signal within one or more solar cells of the solar panel is detected and processed to provide a detection signal corresponding to a distinguishing characteristic associated with the solar panel. In accordance with alternative exemplary embodiments, a light sensor is disposed along a sightline from the solar panel to detect a light emission produced by dissipation of electrical power by one or more solar cells of the solar panel. In accordance with further alternative exemplary embodiments, selective blocking of light to (e.g., shading of) portions of predetermined solar panels causes corresponding changes in output power that can be used to identify affected solar panels.
