Together with the Swedish Energy Agency, the Swedish Electricity Safety Authority has for some time been reviewing solar installations around the country. We wrote about this in December last year here on our site.
The Swedish Electric Safety Authority finds that it is mainly installations with so-called optimizers that cause radio interference. Some plants, on the other hand, have very good EMC properties, so you should not categorically accuse photovoltaic systems of interfering, says the Swedish ESA.
Radio amateurs in the Kungsbacka area have reported disturbances that they believe come from installations with solar panels and the Swedish Electric Safety Authority has recently been there and made measurements. The authority is happy to receive more reports of radio interference that may be due to installations with solar panels. This, in contrast to interference in general and which may conceivably come from radio broadcasts, you must report to PTS.
According to ITU radio regulations , amateur radio is not considered to be “safety service”, which is why you cannot claim interference free in all situations. Occasional strong disturbances may also be tolerated, whereas it is more serious if entire frequency ranges are totally extinct.
In order to look after the neighbor it is always good to communicate with the neighbor before a notification. Therefore, if you suspect a specific installation, you should first ask the neighbor to shut down your plant to confirm the suspicions.
When reporting a suspected malfunction from a photovoltaic installation to the ESA, it should be detailed. Describe whether the disturbance is continuous or how it occurs intermittently. Please attach audio file and pictures from your frequency display. State where and when the observations were made and preferably a little about your equipment. Do you think you know where the source of the disturbance is located and who it is that has it, you can also specify this. Also, keep in mind that everything you write to an authority becomes public action. Send your application to: firstname.lastname@example.org
