Spec.... This entire post by you is one extreme Fantasy.
If my currency is Dollars, and I am forced to take spare Russian Rubbles or Nigerian Naira "Loans" that I don't want, can barely use, and disrupt my dollar business, and I am forced to return those Rubbles in US Dolars of the same numeric value, what Kind of Loans is that?
I have a better idea, let Me keep my Dollars, and the Russians and Nigerians keep their Rubbles and Nairas, and we'll all live happily.
Spec..What you are really doing is this. Any excess good is low value good, that is why it is excess, nobody wants it nor can use it.
You are simply looking for a way to reduce your own costs, you buy into a PV scheme which allows you to pawn off your low value excess energy on the utilities. You convince yourself that you are doing them a favor. Then YOU demand that they turn over their High value energy in exchange for the low value energy that you are forcing them to "Loan".
Don't go telling the utilities that your excess solar power is high value to them, it is not. Don't go telling them that it displaces Toxins, which may not be true if they already use nuclear, their own solar, or their own wind+ Nat Gas.
You should just Man-Up and buy some batteries, and eat your own solar power.
I am not sure if this qualifies as a shell game, but it smells close to it to me.
