How To Compare Installer Quotes

Two quotes can look the same and not be. Line them up on the same terms.

Get These In Writing

• Battery brand and model, usable capacity, and continuous power.
• Which circuits are backed up and whether a new subpanel is needed.
• Total price including permits, interconnection fees, and electrical upgrades.
• Warranty length, what it covers, and who honors it if the installer closes.
• Payment terms: cash, loan, or lease, and the total you pay over time.

Check The Installer

• State contractor license and electrical license, looked up on your state board website.
• Insurance and recent local installs you can verify.
• Complaints on your state attorney general or Better Business Bureau pages.

Take Your Time

A good offer will still be there tomorrow. Be wary of countdown pricing and of anyone who will not put terms in writing.
