Solar sales pitches are designed to make the math look better than it is. We built GoSolarMath.com to give homeowners honest, independent numbers before anyone knocks on their door — panel cost, savings, payback period, and bill reduction, all calculated with 2026 pricing and without a lead form.
The solar industry runs heavily on door-to-door and phone sales, and most "free solar calculators" online exist purely to collect your contact information for installer lead generation. We're not a solar company and don't sell leads — this is a free calculator resource, full stop.
Each calculator uses current national average solar equipment costs, regional sun hour data, and updated tax incentive rules — including the expiration of the federal 30% tax credit as of January 2026. We update our underlying data periodically to reflect current market conditions.
No paywalls or "unlock your results" tricks.
We never ask for your phone number or address.
Current 2026 pricing, no outdated tax credit math.
We don't sell your data to solar installers.
