- pstrateman 2y agoA powerwall is $12k installed. That's about 5 years worth of power bills for most people.

At 131mm American households [1] and $11.5k per PoweWall [2] that’s over $750bn at 50% loading.

- lukan 2y agoChina is starting to mass produce NaCl batteries. They will be cheaper. And also only Powerwalls produced in this quantity would have way lower prices. My point was batteries are getting cheaper every day.
- j16sdiz 2y agoIt could be less stable, if each and every powerwall is slightly out of phase.
