Solar installations often give problems when it comes to polluting the airwaves with radio interference.
Electrical systems such as solar panel installations must comply with EMC (Electro Magnetic Compatibility) standards. That
means for example that there is a limit (limit) is what an electrical
system, such as the combination solar panel and inverter including
cabling, may emit electromagnetic fields (EMF). However, this emission limit is more often than not exceeded. That turned out already in 2014 a study of the EMC Adminstrative Cooperation Working Group in which 14 European countries took part.
