General findings have beeen that panels with "mini-inverters" on the panels themselves are very quiet. Panels with "optimizers" or DC-DC converters on each panel and a main inverter on the side of the house are very noisy! I specifically asked for the mini inverters and mine are quiet, but I can hear my neighbors system several hundred feet away with his "optimizers." You can get a bag of ferrites and clamp them on every panel's output and it will drastically quiet them down.

I have been running 5.8 Kw system using Kyocera panels and SMA inverters now for 20 years. No noise at all. The inverters are less that 6 feet from my radios.
