Yet by that standard, Tesla as well as Amazon are "awful businesses" too. He's not looking to the future, or closely examining why they're losing money.
As for why I think it's an awful business:
1) Huge amount of debt 2) Hugely negative free cash flow (-$790m last year)
Sometimes this can work, but it's absolutely the last thing Tesla needs (they need to put cash to work building out the battery factory and production of the Model 3, not subsidize solar panels).
He wouldn't have done this if he hadn't carefully analyzed every aspect of the situation and concluded it could all be done. He's not just throwing dice in the air. Neither SpaceX nor Tesla could have done any of the things they've done if he was.
That said, purchasing the hardware costs as much as a car, so maybe can't do that.

The retail price of electric power basically never decreases. Therefore, if a solar purchase makes sense today, it won't be regretted later. If it doesn't make sense, i.e. because the cost of financing the loan is greater than the projected savings on electricity spending, then it would be reasonable to wait for higher-performance panels.
I'm pretty sure the big win is giving Solar City access to Tesla's financing facilities.
You could say that for pretty much every service you buy. Yet people keep spending money for things they could do (cheaper) themselves!
If you have a PPA, the installer reaps all of the financial benefits. If you finance the system, you get all of the financial benefits. Its the difference between leasing a car versus financing it and then driving it until the wheels fall off (keep in mind, panels have a 25 year warranty but will still produce above 80% capacity for decades after that).
More like Solar City is going to ruin Tesla's financing facilities.
Not if Tesla can borrow those credit lines, and then lend them out with Solar City installs at a profit.
Not losing $300 Million / quarter.
Musk has lots of work to do for sure.
