I wonder if the lease of the solar panels will transfer to the new owner or they are leased personally to whoever bought them and I wont have to assume the lease if I to buy the house.

Is this a new application or transfer?

Buying personally and transferring later risks the due on sale clause.I'm no lawyer but there's two things that people don't seem to mention when talking about asset protection and LLCs.1) If someone wants to sue you, they can sue you, LLC or not.

I don’t know AL lien laws, but in FL transferring ownership doesn’t affect the ability for a contractor to file a lien.Lien laws are very specific as to timelines, notices, etc that a contractor must follow....reading the statute may help.  

You could just get one under your personal name and later file a quitclaim and transfer title into the name of the LLC.There is a slight risk that the bank could call the loan due, but it is not likely

There are a few other different ways to accomplish it too with just being listed as lien holder on the title and transferring title immediately.

I was thinking a sub2 would work and then transfering the sub2 to someone that has money or someone to partner.

So are you just transferring the deed? 

Easy to track what is owed and has been paid.Free although it takes several days for ACH to transfer to my bank.

As in any transfer of title that violates the due on sale clause of an existing mortgage, the mortgagee has the right to accelerate the note, and complying with state law can foreclose.
