It would seem to me this would be a good person to contact and find out what
the secret is to installing a quiet system.
Also, is solar a good investment for a residental installation in Wisconsin?
Cost of electricity is far less here than in say California so I wonder if the
payback is a long way off as opposed to the investment.
Get some details from your son and post them.

OR Installer, and I guess that makes a MAJOR difference.
My Son works for a local Solar Installer. And I mentioned this to him, and he
said his boss (the owner) is all up on that and their systems are RF Quiet. and
99% of what they install is "Solar Edge"
I wasn't sure if his Boss really knew what RF quiet is or not. BUT....
My Son this summer installed a somewhat Large system that is only like 1000
feet from me.
It is two rows of panels that are like 16 feet tall and close to 200 feet wide!
thats 6400 square feet of panels!
I was dreading it being powered up. But NOTHING! and I mean absolutely NOTHING.
And my location is semi rural.
My noise floor is S=0 and I mean ZERO! If my S meter isn't sitting on s zero
on 40 or up I'm not happy.
So I really wonder, how much is Solar Edge, and how much is shoddy installs?
Because this BIG system I even walked right up to with a general coverage
portable recvr, and NOTHING standing right under the panels!
