About SunReckon: who runs it and how it works
SunReckon helps US homeowners answer one expensive question honestly: does going solar actually pay off for me? It is a free payback calculator plus state-by-state guides to cost, incentives, and net metering — built from primary data and written without trying to sell you anything.
Who runs SunReckon
SunReckon is an independent site created and edited by Matias Mardones. Matias built the calculator, chose its assumptions, and researches and edits every article. You can reach him directly at hubloxapp@gmail.com or find him on GitHub .
SunReckon is not a solar installer, lender, broker, or utility. Matias is not a licensed financial or tax advisor, so nothing here is financial advice — the site’s job is to show the math clearly enough that you can check an installer’s proposal yourself.
Why it exists
Most “solar savings” tools are lead-generation funnels. They ask for your phone number first and often inflate the result — the most common example in 2026 is still subtracting a 30% federal tax credit that no longer applies to homeowners who buy a system this year. SunReckon does the opposite: the calculator runs in your browser, never asks for contact details, and shows every assumption it uses.
How the work gets done
- Data first. Electricity rates come from the U.S. Energy Information Administration (EIA), sun-hours from NREL, incentives from DSIRE, state energy offices and utility tariffs, and federal tax rules from the IRS. Each article lists its sources at the bottom.
- Estimates, labeled as estimates. SunReckon has not installed or monitored solar systems itself. Payback figures are modeled from the public data above, and worked examples are illustrations, not case studies of real customers.
- Tools, disclosed. AI writing and research tools help draft and cross-check some text. Every figure, rule, and program status is checked against the primary source before it is published, and Matias is responsible for what appears on the site.
- Dated and corrected. Every article shows when it was last updated. When a program closes or a rate changes, the page is updated and re-dated.
The full process is in the editorial policy.
How SunReckon is funded
The site is self-funded today. It may show clearly labeled display ads in the future (Google AdSense). Ads will never change what the calculator outputs or which states and programs a guide recommends, and SunReckon does not sell leads or forward your details to installers.
