Is $35,714 to install a solar system with battery storage a fair price?
Project Details
My current electrical bill is approximately $300 per month. My average usage is 1,400kWh during winter and 2,000kWh during summer. I am going to shop around for better financing options as the 9.99% interest rate seems high.
