Is $25,792 to install a 6.53 kW solar system with Tesla Powerwall 3 a fair price?
Project Details
I had a few companies give me quotes and I'm down to 2 companies, both are 4.5 and above rated and reputable. Company 2 had an incentive where they said they could give me 2 batteries; Company 1 matched but with Tesla Powerwall + extended. I'm trying to decide if Tesla would be better or EG4s.
