@mattferrell Yeah I caught a lot of this shit online from my blog post series on getting panels and batteries. Assuming the annual cost of electricity is the same as 2017 when I got the first "wave" done, with wave two and three done in 2019 and 2022 respectively, it will all be paid for in electric bill savings in about 2030. However since rates have slowly increased, that will be actually 2026.
Works fine on cloudy and winter days, can charge my EV for free, and my neighbors in this working class neighborhood are getting solar, despite the "cost".
Plus if the zombie apocalypse happens and the zombies attack the grid itself, I'll still be up and op, probably bitching online about zombies.
