Is $38,200 to install a solar and battery storage system a fair price?
Project Details
I received several quotes from companies with over 10 years of experience and 4.8+ Google reviews, and this quote appears to be the most favorable. I calculated that the system would take 8-9 years to break even, considering the opportunity cost of cash with a 5% inflation assumption and a 5% year-over-year return on index funds. The total cost is $38,200 before a tax credit of $26,700. I chose REC panels over Mission panels, which would have been approximately $4,000 cheaper but are inferior in specifications. While I wanted a larger system, this quote is at my maximum budget, and my original plan did not even include a battery. I plan to inquire about removing the gateway to potentially save costs. I will likely sign with this company next week.
