What is the noise voltage level (or power level into a load) from a solar
cell? For example, if it is -120 dBm and the signals coupled from the
wiring of a solar array to your antenna is 50dB lower, you would never pick
up the -170dBm signal. It would be good to have some measured values to
know if solar cell noise could radiate a detectable signal.
I have also been told by a SolarEdge engineer that the solar cells might be
part of the RFI problem. However, when I asked him to explain why, he could
not. What I would believe is there could be some interaction between the
switching in the optimizers and the solar cells and due to their size, the
solar panels can radiate these signals.

"What does this have to do with RFI? Doesn't most if not all the RFI hash
from solar panels emanate from the inverter, not the solar cells
themselves?"
If you've been on the list for at least a week, there's been extensive
recent discussion of the panels themselves being capable of producing a
considerable amount of noise with references going back roughly 60 years due
to numerous reasons. It's not too common, but it can happen.
