I realize that every installation of PV arrays is different, but I think they 
are being given a bad rap.
For over 16 years, all of my shack has been powered by solar panels, including 
devices that are
operating from 120 Volts AC, produced by an inverter which gets its DC directly 
from the panels.
I've worked DX on many bands using many modes and have never experienced 
problems with
interference.  Maybe I'm just lucky, but I don't think that's the case.
