I've got two local houses that appear to be potentially causing
interference. But recently (last week) I am getting constant wide band noise
on all HF bands. 10 dB increase on 40, 13 dB increase on 15 but only 3 dB
increase on 6 (using HF Yagi for 6 meters receive).
Seems a bearing of 200 degrees which is not towards wither house with solar.
A sharp null in interference 90 degrees in either direction.
Need to borrow a VHF Yagi and all band receiver from my friend to further
track this down.
Interesting thing is the wide noise blanker on the Flex can knock out the
noise completely. The K4D, not as lucky. I can reduce the noise on K4D but
not eliminate it.
Getting back to Tony's comment - I agree. The solar companies are getting
more aggressive with sales and the installation contractors just want to get
the job done ASAP as they get paid by the job. I'd love to sign a petition t
the FCC to request standards for emissions be set and enforced.

Subject: [RFI] Solar Panel RFI Awareness At Dayton
All:
Dayton seems to be a good place to inform hams about solar panel RFI and
it's potential for wide-spread interference. With 400 cases and counting
handled by the ARRL and FCC regulations that carry little weight, this
subject needs to be addressed.
Companies like Kenwood, Elecraft and others as well as tower and antenna
manufactures should be made aware of the potential impact on equipment
sales. They need to get on board with the ARRL and push-back on manufactures
who continue to install horrendously noisy solar installations.
A petition requesting the FCC to act with regard to solar panel RFI is long
overdue. As Ed Hare has mentioned, solar systems along with the wires
attached to inverters and optimizers do not have specific emissions limits.
Ed also points out that this needs to be addressed and that those kinds of
changes to emissions limits are going to take YEARS to resolve.
The FCC needs to hear from 700,000 U.S. hams before things gets out of hand
with solar installations. The ARRL can't do it all.
