SolarWorld is a client of my firm, so I'll disclaim that I am not speaking
in any professional capacity. SolarWorld used to have a ham as one of the
main design engineers and he actually did test the designs to look for
interference and RFI generated by the panels....
Cannot attest to panels produced by other companies.
