I have a SGIP contract with a 3rd party. No powerwalls for the last 9 months. I was told yesterday that there is now a chip shortage. My concerns are that I have until October to complete the SGIP process to get the rebate. I have asked the installer if that date can be extended due to supplier issues. The installer is pissed because they have several installs hung up due to this. Their engineering team is now looking into alternatives. As a Model Y owner I feel that I am getting shafted.
