I agree that it was an outstanding letter and call. I agree with the highlight lists I've seen. One key point I've not seen mentioned which I suspect will work its way into many of the analyst reports is the number of times Elon said the words "guessing", "early days", and "speculative." To me, Elon basically threw out the idea that stationary storage response is "off the hook" in the first week, making it logical to consider a 50% increase in plans for GF1, but added a hedge by using those words I mentioned repeatedly. It was a bit like he wanted the analysts to see where they see the numbers going, but he did not want the numbers he was using to be characterized as guidance (fwiw, I think the words "guessing", "early days," and "speculative" out of context convey more caution than I think Elon was actually signaling, but nonetheless, I do think he was presenting something of a hedge). One other point, Elon explicitly stated that a year from he thinks they'll have a very good picture on stationary storage.
Bottom line, I see the analysts putting in higher valuation for Tesla Energy than I thought they would before the call, but I see that based on best case 2020 Tesla Energy revenue talk going from $4-5 billion to $10-12 billion, but still with a considerably steeper discount than what they put on the vehicle business' 2020 revenue projections.
