[RFI] RFI turn out to be a New Solar Panel installed on Roof of Garage 700 feet away from my QTH

[David Robbins]

If I had to guess you have two or more problems, or have misidentified one of them.

Solar arrays normally make noise only when the sun is on them.  An exception to this would be panels that charge batteries and then have an inverter that runs either all the time or only when the power company is down... neither of them would match a 12 hour on/off schedule, that is a sign of an indoor grow light operation, then the increase to 18/6 hour schedule near harvest time.  And neither solar panels nor grow lights would have data on the strong interference... grow lights just don't have any, some solar systems do have power line data but on mine that is down at 64khz and I would expect most other micro inverters do something like that also.

My guess is that you have found the solar panel making some noise.  You also have a new grow light in the area, maybe in the same house?? Maybe they put in solar panels to cover the extra electric usage of the grow light.  What you are thinking is data is probably the response of the switching power supplies for either the solar panels or grow light to line voltage variations unless there is some other plc system in the area.

Been fighting an RFI problem since early Jan 2017

These New Solar Installations are destroying the HF Bands Big Time here in California.

It’s Happens to be verified by an RFI Engineer who is also a ham AA6PX that as working with Gary Lopes - WA6MEM

Watch this Video

Noise come on at Night for 12 Hour On/ !@Hour Off Cycle 

What should be my next step ?????

ARRL - FCC- AC Power Company 

Help !!!

*************************************************
Interference to Licensed Radio Station by the FCC Primary User Radio Station WB6DJI finally located
*************************************************

Interference came on 1st week of Jan 2017 when this Solar Array was installed to see back Power to SCE Southern California Edison.

Never seen this much RFI in my 40 years on the HF Bands 

Need FCC Help - ARRL Help - Edison Help 

Distance of Maximum RFI is about 600 feet North from this Location - WB6DJI 

Can be heard for 2 blocks South along Anza Ave and Marjorie Avenue along SCE street Light lines

Very Bad Interference ( RFI Carrier strongest at 8.048MHz ) with Carriers ( Slow Data Rate Modulation ) in Amateur Radio Bands ( See Video's ) 

Interference started 1st week of Jan 2017 and continues 

Interference Onto SCE AC Power Mains / telephone Lines and Radiates through out RF HF Licensed Spectrum Band 

Used Magnetic Loop Antenna and Bearings from two 45 degree positions cross over New Solar Array on Neighbors Garage about
8 house's from my location. This was done by an RFI Engineer in my Area.

The RFI get into AC Power and Telephone Lines.
Very strong and gets most of the HF Bands 

Can hear 8.048MHz Signal 6 blocks away along street light power lines in my area 

Location of Solar Panel Installation finally located
21318 Anza Avenue, Torrance, California. 90503

Started on an 18Hour On / 6 Hour Off, then on 2-21-2017 Interference comes on at 11:04pm Nightly and turns Off at 11:03am Daily as of 2-27-2017

Same Strong Carriers with Data in 8MHz Band from 8.084 from 8.1MHz thru 8.4MHz and 12MHz Band 

Violates Part 15 FCC regulations for Interference to a Primary FCC Licensed Station in this Frequency Spectrum by a Consumer Electronics Device
