I put pretty much this system on our house a couple of years ago: 4400 watts from 20 220 Watt panels with Enphase micro-iinverters. I tend to have local noise anyway, but after the system was functioning I tuned to an otherwise quiet band and pulled the switch on the photovoltaics. I could here no difference in noise. My shack is on the second floor with only a few feet or less of attic between me and the panels. I've never observed any problems from rfi getting into the photovoltaic system. Note that I don't run more than ~100 Watts, so I can't speak to what might happen with a full legal limit amp.
The system has worked out very well. We made about 85% of our total electric use the first year, though with the heat this summer I'm afraid that number will drop from air conditioner use...
