I would assume so. If you want the panels removed from the house you have to pay $1,500. I haven't looked at the contract, but from what I looked at it looked like you could cancel and leave the panels on the house. You only had to pay the $1,500 if you wanted them removed.
So maybe a new plan for the shorts to bankrupt Tesla would be to sign up to have Tesla put solar on their house and then cancel after the first month. It would cost them $50, but Tesla has paid for all the permitting, installation, and equipment costs. (Sure they will get their money back eventually but it could put pressure on the FCF.)
But maybe Tesla plans to "securitize" all of these installs and just scrape some profit off of the top, so they don't have to outlay all of the cash themselves.
