Interesting... the Tesla Tiles must be doing installs in the Valley as I get calls about once a month, then tell them I'm in Flagstaff and they say "ah, nevermind, we're not up there yet". I'm personally waiting for cost per installed watt to hit $1, not including energy storage. In preparation I've already upgraded my panel to a solar-ready panel, have a Sense energy monitor, I've removed all natural gas from my home (my insurance went down $385/yr because of this!), no more gas anything, have a tankless hot water system for domestic water and space heating, and should be able to pull the trigger one day soon.
This is a bit off topic though, back to that Supercharger - I am glad it is closer to downtown but I'm really anxious about the new downtown Supercharger... just don't know where yet. It's on the map, but just at the center of town. I started a separate thread for it.
The Solar PV and controllers (huawei) at the Biltmore SC are not Tesla brand. They can't seem to get their solar panels going yet. The Power Pack and Wall are also sold out and going to Australia and other places but not the US. I'd sure like to see their Solar PV and Power Walls all over. Growth at such a fast rate is hard to keep up with products.
