Solar Panels Interfering With Amateur Radio

In the video ali6359 shows strong interference all across the vhf spectrum.

Solar panels interfering with amateur radio.

The radio amateurs have known for a long time that pv installations solar panels could interfere. An inverter converts the dc power produced by solar panels into ac power which is used by common household equipment. Micro inverter system interfering with ham radio. Inverters typically use switching techniques to convert the power and this can cause rf noise if the inverter is poorly designed and not shielded.

Move your coaxial far from solar system ac and dc cable to minimise the interference. Hope it is help. But it only helps marginally. But when the sun is shining like today i can not run the radio at all.

The technical differences between mono and poly crystalline solar panels are very subtle to the radio amateur. As a general rule the biggest problems stem from radio frequency interference on am or ham radio because they rely on weak and variable signals with large antennae which are particularly susceptible to interference of any kind but it doesn t rule out solar for radio buffs. I thought in my quiet mind that it would be enough to turn off the inverter to avoid noise. A good dc power supply and antenna system will not effect you operate hf.

This information is mainly aimed at reducing or eliminating radio tv cell phone and other electronic noise and interference in photovoltaic and other dc powered systems and from equipment used in pv systems. As long as the sun is shining the solar panels continue to provide electricity. Not all hf ham radio got interference from solar inverter you need check your antenna coaxial cable swr.

If you want your ham radio do not put a solar antenna on your roof. For more than 10 years the veron has been warning about the effects of equipment that emits unwanted rf emissions. Radio interference from solar panels rfi. Much of it applies to anything or any equipment with emi electromagnetic interference or rfi radio frequency interference.
