Yes. A solar array for a home about that distance from my SteppIR wipes 
out 6M in that direction when the sun shines (raises noise floor by 10 
dB), and makes a mess on some of the higher HF bands. I only hear it 
when the sun is shining, which suggests that the source is the charge 

If you search my street address on Google Earth you can see my SteppIR 
as a small almost horizontal bar roughly 100 ft north of the house, and 
part of the solar array at about 110 degrees az.

Depending on the system, any bands can be affected.

BTW -- noise cancellation doesn't work on sources that are large as a 
fraction of a wavelength, especially if the source is distributed.
