There is a good QST article here:
APR 2016 -/QST/(PG. 33)
Can Home Solar Power and Ham Radio Coexist?

He does not name the manufacturer, only the installer.
We have a local ham KQ6RS Randy who has had several of these installed
in is neighborhood.
Randy is a retired Qualcomm antenna engineer and has lots of experience
and test gear to find and characterize the interference.
The company (manufacturer of the system) causing most interference
locally is Solar Edge (SE).
Several local installers have installed noisy SE systems.
Randy has given several talks about his problem and solutions.
He has worked with SE to explain why it is interfering.
There is a new system about to be released "soon".
That does not solve the currently installed systems nor the systems
installers have in stock ready to install.
The problem, as stated in the article, is that they use boosters on each
panel and configure the wiring in a loop.
The company has been cooperative by directing the installers to install
toroids and change the wiring to NOT make a loop.
This helps a great deal.
For some reason (expense I suppose) they don't want to change the
recommended installation method.
They have fixed several locally but have recently complained about Randy
giving his talk and "drumming up complaints".
ARRL RFI office has also helped.

Subject: [RFI] Solar Panel Manufacture Schedules Fix For Solar Panel RFI
All:
Solar Edge, the manufacturer of solar panel systems, has informed me that
they will be installing RFI suppression on a neighbors installation to stop
the RFI affecting my station. The job will take place on May 29th, weather
permitting.
The companies field engineer assured me that the fix will work as he's done
many in the past. My neighbor has given me permission to access his home so
I can monitor the process. I'll share what information I gather with the
group once the job is done.
For those who may be having similar issues with Solar Edge systems, contact
Tefford Reed at: Tefford.Reed@solaredge.com or Tom Simpson at:
Tom.Simpson@solaredge.com
I filed a complaint with Solar Edge in August of 2016 so this fix has been a
long time coming.
