Reading the presentation, Musk seems to be saying, "Solar City is great and will be even better if I run it like I do Tesla". And a hand wavy, "we have the same customers."
This seems like an unusually sketchy move from him.
Feels like a "thanks cousin, but now it's time I run this company too" pseudo takeover thing. Personally I don't mind, as an investor in both SCTY and TSLA.
Well, I assume that means the Powerwall, in which case I agree, they do have a lot of the same customers.
I think there's a lot of potential to market Tesla cars/batteries to Solarcity customers, and Panels to Tesla car/battery owners. I wouldn't be surprised to see combo packages sold in the future.
He means the cars. When you buy a Tesla the first thing they do is send you marketing materials to get a Solar City install to charge your car at home, as they are an "approved vendor".
So a lot of people with the cars have Solar City installs on their roof.
