Disclaimer

Estimates are not quotes

Calculator results use state averages and simplified assumptions. Actual production, cost and savings depend on your roof, shade, equipment, utility tariff, installer, financing and future electricity prices. No result on this site is a guarantee.

Not professional advice

Nothing here is financial, tax, legal or engineering advice. Incentives and laws change often. Confirm eligibility with official sources and a tax professional. Electrical work, including connecting batteries, generators or transfer switches to your home, must be done by a licensed electrician in line with local codes.

Advertising and referrals

Simple.solar shows ads through Google AdSense and may receive referral fees from installers when readers request quotes, as well as payments from labeled sponsors. These relationships never change our calculations or recommendations.

External links

We link to outside websites for reference. We don't control them and aren't responsible for their content.

Accuracy

We work hard to keep figures current, but errors can happen. Report a correction.
