Being in the bay area has to be a big plus since installs are definitely being done around here, certainly compared to states they aren't installing at all, and I'd suspect parts of CA they're not working in either. Still being a relatively new thing, I have to assume that there's still a dependency on the complexity of the project, and perhaps size. With v2 they made it pretty clear they weren't interested in taking on projects that were <10kW. Now I've heard of v3 proposals smaller than that, so it seems like that bar has at least been lowered, but I'm not sure it's gone (i.e. they might not be interested in a roof that turns out to only be able to do 2,3, or 5 kW, at least not as quickly as bigger projects). And I do think they're paying close attention to any unusual features of the roof, though I guess that one might go both ways, if there is a feature that they're ready to take on then they might look for a house to try it out on.
I have to imagine there are still original (v1/v2 time frame) deposit holders they haven't gotten back to, yet there are clearly orders since the v3 announce that are already at or near completion. What I don't understand is what puts some of these projects before others.
Curious, is there anyone reading this who is (1) in the bay area and (2) put in a deposit before the v3 announce (and hasn't since withdrawn it) who hasn't heard from Tesla yet? I have to assume such people exist (surely they got lots of deposits in the bay area, and haven't installed that many roofs yet), but I kinda doubt any of them are on this forum.
Anyway, my much less speedy timeline for my v2 install, obviously they've streamlined a lot since:
06/05/17 - Deposit placed
07/12/18 - First contact from Tesla Energy Advisor
07/21/18 - Site survey
09/10/18 - Received design proposal
09/18/18 - Signed contract
10/25/18 - PG&E interconnect documents ready/signed
[In between, pre-construction work (asbestos abatement and power riser code upgrade performed by PG&E)]
12/07/18 - Install scheduled (for 12/17, which didn't work for me due to holiday schedule)
[A few more tries for a schedule fit, one late cancel by Tesla for January, next proposed time (early Feb) not good for me, settled on late February start]
01/15/19 - Powerwall installed but not fully wired (this would have been in the middle of the install date Tesla cancelled, but they did the PW anyway)
02/26/19 - Roof tear-off started
