I notice theyre isnt much concern with the RFI problems as there is with lower efficiency: https://www.sciencealert.com/scientists-identify-a-key-flaw-in-solar-panel-efficiency-after-40-years-of-sear
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? _______________________________________________ R

Don, There was a recent RFI group exchange on this list regarding possible ways that the cells themselves could create some RFI issues. But I don't think this was based on anyone's findings in the fi
Ed: SolarEdge engineers discovered that the panels themselves were generating RFI at several locations. The noise was detected while the panels were disconnected from the system. Tony -K2MO _________
This article is way above my pay grade, but does show that Si panels create RF noise. How much above the top frequency limit of 100Khz shown in the chart may or may not be a problem. However, put eno
"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,
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,
I'll bet the wiring and the expanse of the panels themselves are the antenna for all the digital RFI generated by all the active electronics. Where are the ferrites being placed - between the panels
Im a newbie at this, but as I understand its the optimizers aka conditioners that are some of the problem, the other is the inverter....every panel has an optimizer, in my neighbors case, thats 21...
More correctly, "Some" panels "may" create RFI and that appears to be related to batches from specific fabricators. I would think it might be possible to create an antenna, SA combination to "Preview
It appears they are still researching the cause/mechanism now that they've discovered a source. Signal strength? I've not found any concrete numbers. Theoretically it might be several watts with the
