You're moving in the right direction, Alan. Study the QST article to
learn as much as possible about the concepts. Remember that RF is
radiated by CURRENT flowing on conductors that are not shielded, and
that differential current on a transmission line is not radiated.
Twisting helps that tremendously.
Study my RFI piece. I'd be happy to chat if you want to work through
some ideas and concepts. Yes, inverters integral to panels can minimize
RFI IF the units are properly designed, but that can be a very big if.
:) Also, buy Henry Ott's excellent EMC text and study it. Published by
Wiley, you want the latest edition (c.a. 2007-8).

They quoted a higher price for a lower-power system, but because of
some convoluted accounting it will actually end up costing me less.
And they are at least willing to talk about adding some common-mode
chokes. Their system uses micro-inverters on each panel, which
potentially should cause less interference because all the switching
electronics is localized with short connections. Only 240 VAC 60 Hz
comes out of the panels.
