Is $32,500 to install a 6.9 kW solar system with a Tesla Powerwall 3 and electrical panel upgrade a fair price?
Project Details
I am questioning if the Powerwall is too expensive. I was initially told the ROI was 6 years, but after checking the paperwork, it's actually 10 years with a 12% ROI. I'm also unsure why I need a 13.5 kW battery and 15, 460-watt panels. I feel the $32,500 price without tax credit is not cheap and plan to shop around, as the Tesla website quotes a better deal for a larger system.
