About HomeSolarPayback

HomeSolarPayback estimates how long solar panels take to pay off at your ZIP code, using public government data: NASA POWER sunshine, U.S. EIA Form 861 utility rates, and OpenEI ZIP-to-utility mapping. The number is an estimate, not a quote.

The site is free. Some links go to solar quote partners; we may earn a referral fee if you request a quote or sign an agreement. That never changes the payoff math. See our affiliate disclosure and methodology.
