I believe you have to use the same installer to install both Solar and Powerwall in the same year in order to get the SGIP rebate (someone can correct me on this).
I don't believe this is correct. The Powerwall is eligible for SGIP even without solar. For the federal ITC, you must have solar in order for the Powerwall to be eligible, but as long as it's installed after the solar I think it should be ok. I got my Powerwall a year later than my solar system and got both SGIP and the ITC. The Powerwall was installed by Tesla and the solar system by a local independent installer.
