Radio interference from solar panels

VERON reports the Netherland's communications regulator Agentschap Telecom
has given tips on preventing interference from solar panels

A Google translation reads:

The radio amateurs have known for a long time that PV installations (solar
panels) could interfere. For more than 10 years, the VERON has been warning
about the effects of equipment that emits unwanted RF emissions. That
started with the Power Line Communication devices.
This makes it easy to make an ethernet connection via the mains without
having to install a UTP cable. Very popular with internet suppliers to
connect a second television set at low costs.

But it doesn't stop there. There will also be PV installations (solar
panels) whose converters and optimizers cause interference on our HF tires
and even above that. All equipment is now equipped with switching power
supplies up to our LED lighting. That has not gone unnoticed by the VERC's
EMC-EMF committee.

Agentschap Telecom wants more insight into the causes and the prevention of
interference by solar panels. That is why Agentschap Telecom has contacted
various market parties. To come to solid solutions together. A number of
tips can be found on the Telecom Agency website to prevent interference.
Including the use of CE marketing approved PV installations, laying cables
side by side, using ferrite etc. Read the full article [in Google English]

Jaap PA3GYM had an unpleasant surprise in Amersfoort. Immediate neighbors
placed solar panels on their roofs. The consequence; at Jaap, the signal
strength meters of its receivers turned out to be full. He suffered a lot
from interference . He asked the VERON EMC-EMF Commission for help . And a
process from failure to solution was started. The VERON EMC-EMF Committee
discussed these results with the AT during the frequent Amateur
Consultation . The AT saw a good opportunity here to regard Jaap's
situation as a " testing ground ". We save you all the details which can be

It's about the result. The interference was considerably reduced, see this
