I only know one person who successfully got one installed, and his installation was endlessly delayed, after which their paperwork got screwed up on Tesla's end so they had it for free until they sold house (not sure if they ever got charged for it honestly). It worked, but reportedly wasn't as efficient as panels would've been.
