Thank you Mike for keeping at it here... I will be moving to Arizona
sometime in the next few years, and this was one of my worries... THANK
YOU for "ice cutting" this.
73s and thanks,
Dave

After an on-site visit and testing by an FCC Enforcement Agent of the ~S9
interference cause to my station by a Solar City solar array located 2
houses away, the FCC issued Solar City a Notice of Violation.
It appears that at least one of the primary interference generating
components is a load balancing device called an "optimizer" which is
attached to back of each solar panel. Testing by the FCC Agent showed that
the interference does not stop until the optimizer is detached from the
solar panel. Attempts by Solar City to add filters were unsuccessful and
only resulted in a few DB of change.
The optimizer (as well as the the rest of the system) is manufactured by
Solar Edge. I was told by Solar City when I inquired about them installing
a different type of system that this is the only kind of system that Solar
City installs. Given this it's not hard to envision that many Solar City
installations are causing this type of interference. Fortunately the FCC is
concerned about this issue and is actively working to resolve it.
