Maybe someone out there can help me with cost justification on installing 2 Powerwalls. The quotes I’m getting are between $23,000 and $25,000 before FTC and SGIP. I’m retired so the tax credit is not that useful and step 4 on the SGIP is around $7,000, so a net of just over $18,000. Since I’m not sure how many times and for how long the power will be out it seems like a lot of money just for backup. If I could save some money on my PG&E bill it might make sense, I have solar and I’m with our local CCA. What works for me right now is my peak kW is from 1 to 7 and the credits I get back from high solar generation at that time make my system work. Not sure if I could save money with the addition of Powerwalls.
