Terms of Service

Battery Calculator provides informational estimates for household battery planning. By using the site, you understand that results are estimates and are not financial, legal, utility, or installation advice.

Accuracy and eligibility

Program rules, rates, equipment eligibility, and incentives can change. You are responsible for confirming current terms with the utility or program administrator before signing a contract.

Use of the site

You may use the calculators for personal evaluation of a battery quote. Do not rely on the results as a guarantee of savings, program enrollment, tax treatment, or payback.

External sources
