I'm in the SF Bay Area (Tesla's backyard). Ordered my Powerwall in February, had my site inspection in April, and got my quote and put down my $500 deposit in May. Then last week I got an email saying that they can't give an estimate for installation, and that I won't hear from them for another six months.
Here's the main part of the email:
"Due to current product limitations we have placed all Powerwall projects on hold pending a formal installation timeline. Once we have a definitive timeline in place, we will begin moving forward.
"In the past we have provided soft timelines but have had trouble keeping to those expectations. In the best interest of our customers, we are now holding off on providing timelines that we are unable to honor. We appreciate your patience as we work to meet the growing demand of this product. I will reach out again within 6 months once we have an update."
