How long until solar pays for itself in Rhode Island?
In Rhode Island, solar panels pay for themselves in about 7 years. That is faster than the U.S. average payback of roughly 8 years. After the payback point, the electricity your panels produce is essentially free for the remaining 15+ years of their warranty.
