So much misinformation out there about #hamradio and solar system interference. Some systems create horrible interference and some don't. I decided to add a little bit of real test based first hand knowledge to the world instead of the usual rumors and gossip.

I recently got to go on site at a 30+ panel install using silfab panels and enphase iq8 micro inverters to test.

Strung up a spark plug gear end fed wire antenna and attached it to my #x6100 radio. Radio and antenna wire less than 50ft from the solar system. Set it to rf gain of 50 and checked every supported band, 6m to 160m. Testing was done mid afternoon on a clear sunny day and the owner confirmed that the system was running at about peak output, which by my reasoning should make any interference as loud as possible.

Background noise was S3 or quieter across all bands except 160m which was S4.

I consider that confirmation that those specific panels and inverters are not noisy when properly installed and grounded. Confident enough that I'll be getting a similar system installed on my home.
