BTW.... its probably not apparent from my other posts in this particular thread, but, I LOVE (love love) having my 2 powerwalls. It only takes one multi day outage, when you have solar on your roof already and the sun is shining, to get extremely frustrated at " WHY THE @!#$%!@#! is my solar not working!!!!" (at least for me, anyway lmao).
Knowing that I can either "live like normal" during a shorter outage, and/ or reduce consumption to go longer if needed, still enjoying things in my home, is immensely gratifying to me.
They dont pencil out financially though, especially since I am still on NEM 1 (until they take it away from me, anyway). Still, I am super happy with them, glad I bought them, etc.
I still think the value proposition is a personal one though, and if there isnt some intangible value there, its hard to make them pencil out. I still love them though.
