Terms of Service

Last updated July 2026.

These terms cover the calculators, guides, and state pages on SolarPanelCostGuide. Using the site means you accept them.

What the calculators are for

The four calculators and the state-by-state guides exist to help you understand solar cost, the 30% federal credit, payback, and system sizing before you talk to an installer. They run on formulas you can see, using inputs you control. They are not a quote, a contract, or a substitute for a site assessment.

Figures can be wrong or out of date

Tax credit rates, average install costs, and state incentive programs change over time. We update pages when we catch a change, but cannot guarantee every figure reflects the current year. Verify credit eligibility and rates directly with the IRS or a tax preparer before filing anything.

Not tax or financial advice

Nothing on this site is tax, legal, or financial advice. The tax credit calculator estimates a federal credit amount; it does not account for your specific tax liability, filing status, or other credits that might interact with it. Talk to a licensed tax preparer before relying on any number here for a return.

Content and other sites

Text, calculators, and design on this site belong to SolarPanelCostGuide unless otherwise noted. Links to government sources and other Encore Editorial sites are provided for reference; we don't control or vouch for everything on those sites.

No warranty, limited liability

The site is provided as is. We are not liable for decisions made based on calculator output, installer contracts you sign, or losses connected to using this site or any site it links to.

Changes

We can update these terms at any time. Continuing to use the site after a change means you accept the new version.
