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.
