[Elecraft] OT - Radio interference from Solar Panels

[Barry]

Bob,
     It isn't just a problem in Sweden. We have seriously here in the 
U.S. Panels put in my Solar City annd a another company, I can't 
remember the name, are also rather problematic. They make no effort to 
suppress the noise caused by both the equalizers nor the power 
converters. There are typically no use of ferrite's, conduits, or 
twisted wire. There was an article on this in QST a while back, and 
several local hams have complained to the installation companies and 
have had them respond and make repairs. I do believe that ham radio as a 
service under the FCC is protected from these sorts of things.

73,

>Sweden's national amateur radio society SSA reports:  Solar panels are becoming more and more common.   An increasing problem is that interference can be created to radio reception.   The newsletter (LÄNK) from the Swedish Electricity Safety Agency states that they are looking more closely at the inverters and optimizers found in solar panel installations.  The Swedish Electric Safety Authority is doing this together with the Swedish Energy Agency in a project that is ongoing until March 2020.
