    Can a PV solar panel rectify an rf signal from an amateur antenna nearby, causing RFI ?

    Not that I have ever heard of. If it could, I would have a persistent RFI problem at my station as I often run 100% from an off-grid system. Also, my OCFD passes over the panel array at some point. I think the point here is that while transmitting, you wouldn't notice any RFI anyway as the receive mode is disabled. Are you speaking of some other type of RF not generated by your station?

    Thanks
    I understand that the PV panels are actually semiconductor material, thus they may be probe to rectification of nearby strong Rf from ham tx

    Well, if this is true, it would be the first time I've heard of it. Do you have an example of this phenomenon that you can share?

    This is just a tought. I can prove nothing.
    I may study again the semiconductors theory especially silicon material.

    Is a PV panel actually a diode?

    The issues with PV panels is usually not with the panels as they generate DC, but with the inverters that turn the DC into AC. I have never heard of a panel by itself causing RFI.
