Maybe this is a good place to ask. During off-peak hours my local utility charges $.025/Kwh versus $.25/Kwh for peak. If I charged a 11Kwh Telsa powerwall, I could easily get through the day on $.025/kwh electricity, even on hot days, and the payback would be something like 11 years. Why wouldn't this be cheaper at grid scale and why isn't it doable today?
