Part 2. - SCTY
So I must admit I wasn't 100% happy about this either, mainly because of the questionable financial background of SCTY and the distraction it can provide to Elon and co. But 2 things tell me this will still be a great move in retrospect.
One, is Elon and JB. Like others, I trust those guys and think if they are on board I either continue to trust them or sell my TSLA. This is not blind trust, just logic based on past performance.
Two. On the consumer market this may be the next "iPhone moment". Apple didn't invent the smartphone, but Jobs found the flaws with how other manufacturers designed/presented them to consumers. Elon the same way, realizing if the design can be attractive and easy to deploy, consumers interest will rise. If Tesla can take you off the grid with an integrated panel-inverter-storage design that is installed by 1 team in a few hours/day, that's a major feat. They will also have pricing on their side, as the new panels will be 20-30% more efficient than mainstream ones used today, meaning you may need that much less of them. Panels and inverters are both very expensive today and your return is 5-15 years depending on your country/state and incentives. If a combined Tesla advanced PV panel and inverter design can make that 1/4 less expensive and it even looks good, well, that may be a no brainer. And if you can afford it, they can add a Powerwall to the mix with the cheaper GF1 cells and you can go completely off grid.
Three, and this is the big one. On utility scale designs Tesla will be able to deliver complete, turn-key power plants at a fraction of the time and probably less cost than building a new peaker gas plant. OK, ok, so there are probably a few other things that go into a power plant, but you get the idea, they can deliver the guts of the plant in one deal in a matter of months. PV + inverter + Powerpack.
I haven't quite finished the Elon biography yet, but what is already clear to me about the man is that he felt he got burned every single time he let things out of his hands, when he had to depend on 3rd parties and outside vendors. Look at what Tesla has been doing with insourcing much of their component production - the total opposite of what the rest of the vehicle industry was doing. Fact is, and Mobileye is the latest example, no outside partner can , or is willing to match Tesla's development speed. Elon is taking much higher risks and doing much more revolutionary, ground up new designs than what standard corporate culture would allow. So yeah, maybe it would have made sense to snatch up SCTY a year from now when M3 is already in production, but by then SCTY would have either gone bankrupt or would have been too expensive due to the success of the new panels and he wasn't going to risk that.
