I expressed interest in the PowerWall yesterday on the Vector web site. Out house does not have an ideal roofline for Solar, but I was interested in the PowerWall as a standby power supply.
I received a call form a very helpful Vector gentleman a short time ago and was given an approx $15,000 installed price. Higher than I expected, and certainly higher than I can justify spending at this point. My Googling had given me the impression that it might be in the $5000-$6000 region which may have been affordable for my intended use.
Dreams are free. Storing power is not. Oh well. I can potentially potentially come up with a DIY solution, but the PowerWall would have been much more attractive on the wall.
