Is $27,456 to install a 6.44 kW solar system with 10 kWh whole home battery backup a fair price?
Project Details
I am new to solar and am seeking a sanity check on this proposed system. I am located in southern California and am under Nem3.0. I am uncertain about the battery investment as my household does not consume a large amount of electricity, roughly 8000kWh annually, primarily due to EV charging. I am considering if the whole home backup is necessary given my consumption or if I should negotiate a lower price without the backup, especially since a battery is needed for net metering.
