The USKA report the magazine Photovoltaik carries an article about the interference solar panel installations cause to radios
A translation of the USKA post says:
What we radio amateurs have known for a long time has now been publicly and well-reported.
The specialist magazine Photovoltaik has devoted its edition 2/2020 to the subject of radio interference from photovoltaic systems. The trigger was radio amateurs from Switzerland who had registered with the magazine.
Editor-in-chief Heiko Schwarzburger, himself a qualified engineer MA, has written three very insightful articles based on interviews with experts on the subject and those affected.
The first article is an interview with Heinrich Häberlin, HB9AZO, professor emeritus at the Burgdorf University of Applied Sciences and operator of his own photovoltaic system. As the publisher of a comprehensive standard work on photovoltaics and many other publications, he is an important voice in the industry.
The second interview was conducted by editor-in-chief Schwarzburger with dipl. El-Ing. ETH Emmanuel de Raemy from OFCOM, responsible for EMC issues. Mr. de Raemy is a regular participant in the meetings between OFCOM and USKA, which take place twice a year. He also clearly explains that the disturbances of PV systems are a problem for all radio services. However, it is usually the radio amateurs who are the first to discover and can assign them thanks to their technical knowledge.
In the third interview, a radio amateur spoke, who had such a hard time with the service provided by the unintelligible manufacturer because considerable faults were found.
We thank editor-in-chief Heiko Schwarzburger for the very informative and well-founded contributions on the subject of EMC interference from PV systems, and hope that the awareness of the problem will raise the awareness of the installers and builders.
Bernard, HB9ALH
