Is $37,000 to install a solar panel system with battery backup a fair price?
Project Details
This is my top quote from a reputable company in Southern California with many great reviews and years in business. I'm happy with their warranty terms. They can install the system 1-2 months before the tax credit expires, and the quoted price of $37,000 already accounts for the credit, which they will handle. I'm adding a second electric car, which is increasing my energy needs. I've been assured this is a purchase, not a lease or PPA, and I will be reviewing all contracts carefully on Thursday to confirm this. I'm also curious if using power while producing will affect what's sent to the batteries. For my previous home, I used Project Solar, which offered a great price but used subcontractors, and their responsiveness has been zero this time, so I opted for a more established company for peace of mind.
