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.

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

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
