Received a call today from Solar City to schedule my Powerwall x 2 installation. Tentatively scheduled for December 14 and will take 2 days to complete. I'm not sure if there have been any installs in Houston but I ordered mine back in April. My Solar installation was completed in August and the trifecta will be complete whenever the Model 3 arrives. Are there any Powerwall installations in Houston and, if so, what is your opinion?
