I have NEM 2.0 and 25 kWh of batteries. They'll be "paid for" in about 5 years because I load shift from $.81/kWh to $.15/kWh in summer. For example, during peak, my system will feed 100% of my solar back at the $.81 rate and then charge back during the $.15 off-peak. Penciling it out, this saves me an average of $12/day in charges. 5.4 years and then I saved more than I paid AND have whole home backup AND continue to save ~$300/mo. Two EV household, multiple kids, etc. We use more juice than we should.
