Solar panels and PW installed last year. In October, 2022, Tesla tech discovered that the junction box on one of our panels is stuck in the "off" position which results in all downstream panels not delivering power so production is cut in half. Repair was scheduled for November 3rd but before then, Tesla called and canceled claiming lack of crew availability. Turns out they were installing a new system at one of my referral's home on November 3rd. I have chatted and talked with customer support but they will not do anything. Now it is December 11th and I find out they are installing new panels on another referral's home about 2 miles away! Still won't come fix my existing system. They also claim to not have any responsibility for the lost production and that all I get is their "repair promise." BUYER BEWARE - once you pay Tesla support goes away!
The install teams and repair teams are not the same. That doesnt excuse it, but its the fact of how its setup so the installations at your referrals homes have nothing to do with your repair.
They do take way too long to fix something though, and there is no performance payback guarantees.
