Terms of Use

Last updated: July 28, 2026

Acceptance of these terms

By using ClearWatt (clearwattguide.com), published by Clear Watt Guide, based in Spain, you agree to these terms. If you don't agree, please don't use the site.

What this site is

ClearWatt publishes educational articles and an interactive calculator about home solar costs, incentives, financing, and equipment for a U.S. audience. Content is provided for general informational purposes only and does not constitute financial, tax, legal, or engineering advice. See About & Methodology for how we research and source what we publish.

The calculator and other tools

The solar savings calculator produces estimates based on the numbers you enter and a simplified, disclosed methodology. It is a planning aid, not a quote, and we make no guarantee about the accuracy of its output for your specific situation. Always verify figures with a licensed installer, your utility, and a tax professional before making a financial decision.

No professional advice, no guarantee of outcome

Nothing on this site should be relied on as a substitute for advice from a licensed professional who knows your specific circumstances. We are not liable for decisions made based on information published here.

Intellectual property

Article text is © ClearWatt unless otherwise noted. You're welcome to link to our pages or quote short excerpts with attribution and a link back to the original article. Photography used on this site is licensed from third parties — see the Photo credits section on the About page for the specific license and attribution required for each image; those licenses, not this paragraph, govern reuse of the photos themselves.

Third-party links and advertising

Articles link to external sources (government agencies, research organizations, manufacturer documentation) for verification. We don't control those sites and aren't responsible for their content. This site also displays advertising served by Google AdSense; see our Advertising & Monetization Disclosure and Privacy Policy for details.

Governing law and jurisdiction

These terms are governed by the laws of Spain, without regard to conflict-of-law principles, since Clear Watt Guide is established there. Any dispute arising from your use of this site that isn't resolved informally will be subject to the exclusive jurisdiction of the competent courts of Spain. This doesn't remove any consumer-protection rights you may have under the mandatory law of the country where you live, if those rights can't be waived by agreement.

Changes to these terms

We may update these terms as the site evolves. The "Last updated" date at the top of this page reflects the most recent revision.
