Let’s review Solar. Solar is not a good investment.  The only thing that can 
make it palatable are tax benefits.  There is a 30% federal tax credit 
available.  Even with this credit in most cases it will take ten years or more 
to amortize your costs.  There are exceptions and more local tax incentives 
Most “high efficiency” solar controls cannot be made RFI quiet.  If you are 
purchasing a solar system ask to see previous installations and make sure they 
are RFI quiet.  Write in the contract (this goes for any electrical thing you 
are purchasing) a clause that says it will not interfere with your radios and 
will be as quiet as the systems you have inspected.
I have had a terrible time with a high efficiency America Standard HVAC 
systems. I have just finished two solar systems that are RFI quiet.
Light bulbs:  Some make noise and some do not.  The problem is you go to a big 
box store and purchase bulbs that you test at the store and they are quiet.  
You go back to the same store and buy the same bulbs and they are noisy.  
I recently purchased forty plus LED fixtures to replace noisy florescence 
fixtures  from Super Bright LED and they assured me they would be quiet and I 
wrote it in the order with the man's name that they would be RFI quiet and they 
were quiet. 
You need to shop with your RFI detector and a bulb adapter plug.
How do you deal with RFI.  Hopefully someone in your area has a relationship 
with the local electric company and has been working through problems. It might 
be your ARRL Technical Specialist but someone at your local club knows who is 
the go to person. This is where you start.  Do as much work as you are able to 
do yourself in identifying the problem. Poll numbers, addresses, Screen, shots 
whatever you can do. If this does not work call your ARRL Technical Coordinator 
or Section Manager for help. If they cannot help they will refer you to the 
ARRL Newington.
