As solar panel prices have dropped, roofs that weren’t “economical” for solar a few years ago work just fine now. For example, this system is on a roof that is only 70% of the ideal (meaning 100%), yet the system will pay for itself in about 6.5 years.
After that, all the savings and green income go right into the homeowner’s pocket!
