"I would be interested in the technical reasons how a solar panel can make RFI. Is there some switching circuitry connected to it? In other words, are there more than just solar cells in the assembly called the panel? I don't see how a non-switching component (such as a solar cell) can generate any RF. Radiated RF requires fast rise times, insufficient filtering and something to act as the antenna."

See my recent post about a small panel connector only to a meter, with the output appearing to be modulated, similar to voice. This was a small panel, about 4"x6", just the plate, with the silicon, connected to a meter.
