I’m in Vegas, near 215/S Eastern area.
I ordered a 12.24kWh system with 2 PowerWalls in late August 2020. Had to get a 200A power box upgrade and an HOA approval before Tesla would continue my order. After that they installed everything Dec 1 and I got PTO on Jan 6(due to holiday schedule with NVEnergy).
I had a few personal issues with items I was not pleased with, but Tesla fixed them quickly without pushback.
My install crew was very good and friendly. They brought extra crew members to get my system installed in 1 day instead of the scheduled 2 days.
