1. A method for automatically detecting arc faults in a solar panel system, the method comprising:
scanning a frequency spectrum of the solar panel and logging locations of a plurality of valleys in the spectrum;
monitoring the plurality of valleys to determine if the plurality of valleys rise above a threshold value;
reporting a fault status when the plurality of valleys rise above the threshold value;
automatically disabling the output of the solar panel upon the determination of a fault status.
