We've had an awful experience with Tesla - our installation was not run of the mill, and I spent quite a bit of time educating the sales people about how our system would work with a whole home backup (they would not let me talk with engineering directly). It probably took 3-4 months to get a build-out, and the cost increased about 75% (almost double), and included a "pad", which sales couldn't explain to me why it was needed.
Needless to say we were NOT happy, but decided to accept the new pricing given that PSPS was a few months off. Tesla submitted and got permits approved and the install date was set 2-3 months later.
On install day, the electrician decided the project required moving a sub-panel to a different location due to height limitations in the work area to comply with code. This was despite the fact that I had sent Tesla pictures months earlier and provided the height of the room - they were well aware of these facts before they submitted for permits. The Tesla sales team said I had to sign a new agreement with another $7k price increase, but Telsa never sent it, the "field manager" pulled their team from the worksite (the powerwalls were onsite and ready for install) and I have received no substantive response from them since.
I'm told by sales that the "executive team" will reach out, but we never hear anything back - it's been about a month now and the install was supposed to be completed back in August.
I'd be curious if someone has an inside contact at the company.
We also applied for SGIP early on under the equity resiliency program, and Tesla since upped the price more than one in their revisions, so our current pricing doesn't match the SGIP application exactly. I'm not sure if this will bump us out, but we're under funded on SGIP at the moment. We can't reapply since the equity resiliency program in the PGE area is already maxed.
If we can't do SGIP, then we'll need to cancel since I'm not going to pay $52k out of pocket. This would be a massive bummer given that we started the process in early February.
And "yes", our house luckily survived the latest Glass Fire (barely) despite the fact that our new onsite water system was disabled due to the lack of electricity.
