RF pollution from solar panels

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.

Climbing a 363m Radio Tower in Donebach Germany

We actually managed to climb a 363 meter high transmitter tower.
These towers are the highest in Germany, right behind the television tower in Berlin. The antenna was switched of on the first of January 2015 and through that, with no risk of radiation damage accessible.
Therefore, as far as I know, we are the first ones to achieve this goal.
An absolutely stunning sight!!!
