Frequently Asked Questions

What is a good solar payback period?

Most residential solar systems pay for themselves in 6-10 years in the US. In states with high electricity rates and good incentives (California, Massachusetts, New Jersey, New York), payback can be as fast as 4-6 years. In states with low rates and few incentives, it may take 10-14 years. Since panels last 25-30 years, everything after payback is pure savings.
