Is $27,131 to add a 5.72 kW non-export solar system with 27 kWh battery storage a fair price?
Project Details
I’m in Southern California and currently have a 13-panel system from 2020 on NEM 2.0. I’m looking to add a second, non-export system so I can keep my NEM 2.0 status and increase evening/night coverage plus backup capacity. I'm asking for a review of this solar quote to see if there's anything I should change.
