Tesla House Battery / Utility Scale Battery

Well, some more news re the PowerWall....

1. SolarCity has stated that it will not be installing the 7kWh system, but will instead offer its own off-grid system in the near future. Snub!

2. SolarCity will install the 10 kWh backup system to interested customers for a $7100 installed, or leased for $5k.

3. The backup unit and the 100 kWh PowerStack grid storage system (for $25k) are 'sold out' through next year, anticipated production is already booked.

100 kWh for $25k is interesting to me! Wonder what that is in Cdn$. Much more no doubt.

Yep - the Bloomberg article says that Tesla is selling batteries at a loss, and they won't sell the 7kWh battery at all. No doubt, the 7 kWh and 10 kWh battery are just the same battery but with different ratings for discharge rate and number of cycles. Therefore, they make $500 more on the 10kWh battery. But that doesn't even allow them to turn a profit, so the real price is $7140 purchase or $5000 lease. Why the discount on the lease? Likely so that they can retain the rights to control the storage capability and make money off of that.

Yawn. I'll check back in 3-4 years.

That price is with installation and inverters, and not a direct reflection of Tesla's loss.
