All:
Interesting article below about solar panel RFI in Sweden. Not a good
outlook for hams if this trend continues.

Interference from solar panel installations
Sweden's national amateur radio society,*SSA*, reports on work to
identify and resolve the radio interference that is caused by solar
panel installations
A translation of their post says:
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
