About SolarPaybackCalc

SolarPaybackCalc is an independent tool that helps homeowners understand the real economics of going solar — without the sales pressure. We are not a solar installer and we do not sell leads. Our only goal is to give you an honest, transparent estimate so you can judge a quote on your own terms.

Who writes this

The site is run by Marcio, an independent tools builder. Every article here is written or reviewed by a human with hands-on experience, and we update the numbers as costs and incentives change.

How our estimates work

Our calculator starts from your net system cost (price minus incentives) and projects savings over the 25-year warranty life of typical panels, accounting for utility-rate increases and gradual panel output loss. The methodology is explained openly on the home page. Estimates are exactly that — estimates — and your actual results depend on your specific quote, roof and utility.

How we stay free

This site is supported by advertising. Ads are clearly distinct from our content and never influence the estimates the calculator produces.
