- Site purpose
- Explain residential solar payback before a homeowner enters a quote funnel.
- Revenue model
- Contextual advertising may support the site, but Solar Payback Map does not sell homeowner leads.
- Data approach
- Public production, electricity, cost, and policy sources are translated into conservative payback ranges.
- Decision limit
- Estimates screen location-level economics and do not replace property-specific quotes or professional advice.
Why we exist
Deciding whether to put solar on your roof is a five-figure decision. Some websites that claim to help are also paid when a homeowner becomes a sales lead. That incentive can make optimistic assumptions feel normal.
Solar Payback Map is built as an editorial and data product. We take public U.S. data, run it through a deliberately conservative model, and explain what the estimate says, including when solar may not be worth it where you live.
What we believe
- 01
Honest beats optimistic
A conservative estimate you can trust is worth more than a rosy one you cannot.
- 02
Show the work
Every number should point back to a source and assumption. No black boxes.
- 03
Ranges, not false precision
We publish payback as a band because a single decimal is usually a promise the data cannot keep.
- 04
No incentive to mislead
We do not sell leads, so we have nothing to gain from talking you into solar.
How we make money
Plainly: advertising, not your data.
Solar Payback Map is supported by contextual display advertising. We do not collect your contact information to sell to installers, run a quote marketplace, or take referral fees that would bias a recommendation.
Because our revenue does not depend on talking you into solar, we can afford to tell you when it is a bad idea.
The data behind every number
We stand on the shoulders of U.S. agencies, national labs, and public policy databases, and we cite them wherever the numbers appear.
