Terms of use

Last updated November 12, 2026.

Using this site

AskSolarEnergy provides calculators and reference content related to solar energy systems. By using this site, you agree to the terms below.

The calculators are estimates

Every number a calculator produces is an estimate based on the inputs you provide and the assumptions built into that tool. Results can differ from what an installer quotes, what a utility credits, or what a system actually produces once installed. See the disclaimer page for more on this.

No professional advice

Nothing on this site is financial, legal, tax, or engineering advice. Decisions about purchasing, financing, or installing a solar system should involve a licensed professional familiar with your specific property and jurisdiction.

Content ownership

The text, design, and code on this site belong to AskSolarEnergy unless otherwise noted. You're welcome to link to any page here. Reproducing substantial portions of our content elsewhere without permission isn't allowed.

Third-party data

Some figures on this site reference public data from sources like DSIRE, the National Laboratory of the Rockies (NLR), and NRCan. We don't claim ownership over that underlying data, only over how we've organized and presented it.

No warranty

This site is provided as is. We work to keep the data current, but we don't guarantee that every figure is accurate or up to date at the moment you view it. Programs and rates change without notice from the agencies that run them.

Limitation of liability

AskSolarEnergy isn't liable for decisions made based on information from this site, including financial outcomes from a solar purchase, installation, or financing arrangement.

Changes to these terms

We may update these terms from time to time. Continued use of the site after a change means you accept the updated terms.
