Its not super bad. $55/month per powerwall. With them running around 10-15k installed, you get roughly 20yrs out of the battery pack before you could have "bought" it for the same price. That likely lines up to effectivly 2x end of life, with most of these packs estimated to last 10yrs or so. So its really a deal at up $110/month.

Of course, it carries some issues when selling the home like leased solar. Lease to own would have been a better system, but apparently people are happy to sign up without it, so im not suprised they aren't offering it.

Overall, its a really good idea. With enough distributed battery packs, you not only gain breathing room in outages, you reduce the need to spin up dirty, expensive to maintain *baseline" load generators like coal/natural gas/etc.

You can get more and more out of renewables overall with more storage, and with powerwalls and other options, utilities now have a convient way to improve service resilience and go greener while using customers homes as energy storage. Win win.

Why would a regulated infra company helo its customers achieve energy security
