Solar by State

Terms of use

Last updated 7 October 2026

General information only

Everything on Solar by State is general information and estimates based on public data and state rules as we understand them on the date shown on each page. It is not a quote, nor legal, tax or financial advice, and it does not take your circumstances into account. Utilities and installers apply their own tariffs and prices, and rules change. Before you act, check with your utility and get quotes from licensed installers.

Calculators

The calculators give estimates from official base figures. They are not a decision on your application and we do not guarantee any outcome.

Liability

We work to keep the site accurate, but to the extent the law allows we are not liable for decisions made on the basis of its content. Links to other sites are provided for reference; we are not responsible for their content.

Copyright

The text, calculators and design are ours. You can quote short passages with a link to the page. Official figures and laws belong to their publishers.

Law

These terms are governed by Spanish law.
