John,
I have a 5.4kW array of 15 panels on the south-facing roofs of my house.
They use Enphase microinverters, so they put out 240VAC which is synced
to the 60Hz signal from my electrical provider (we are on net metering),
so there is no 'house' inverter.
You can see the output from my array here:

I have had ZERO RFI from this installation. We have a local radio club
member that has done extensive work with solar on his house, and had
experimented with a couple of panels and Enphase microinverters before
committing to a roof-full of them. He also has another array which is
DC, and connected to a DIY Solar inverter. DIY Solar is owned by a ham,
and his inverters are very quiet, also.
Hope that helps.

had
regarding the inverter as an amateur radio noise source would be of
real
interest. Noise may vary by Mfg or by inverters at each panel on the
roof
vs one system inverter near my basement. My antenna is a Hex beam an
the
solar system would be about 15' away.
