I think I asked a few times as well and never got anything until the permit plans showed up at the house. Then I scanned them to my computer. You can check with your building department. It may be more difficult, but you may actually get them vs Tesla may have policy not to send because it would just lead to more questions and requests from guys like you and me. All I can say is that in the end I was very happy, even though it took several attempts to finish install and they failed final inspection. Its working better than I expected and install is done professionally. If I didn't mention previously, they consulted me the day of for where I wanted everything. When I resisted they said they only include normal install in price but I could make request for it to be done how I wanted it, but there could be additional cost. I caved at that point and let them put things where they made sense and I was happy with the end result.
