those optimizers enable the array to work better when there is shade
on some of the panels..( I believe)
usually a few shaded panels can cut output way back from otherwise
illuminated array....
I have 2 SMA 5KW boxes, ( no optimizers) and absolutely no
noise made ( designed) in Germany.. where solar is
EVERYWHERE.... and SMA dominates the biz
I'd go over to the police dept before they install and make them aware..
and good luck with Solar City if they olny use solar edge..

I am waiting for a large solar panel array to be put up next to a
fire/police station and have those RFI issues present...it won't be long
before they are "dismantled". How come some solar panels can be used w/o
optimizers? Are they more expensive ?
These optimizers can be "calmed" down by using proper RFI engineering
techniques but to save a few $$$, the companies building them just don't do
this............and probably "made in CHINA", where else, eh?
