How to check a solar installer's license and bond in California

Solar, batteries and heat pumps are big purchases, and the company you hire matters as much as the equipment. In California, a few minutes on the Contractors State License Board website tells you whether an installer is licensed, bonded and in good standing.

What the bond is. Every active California contractor license needs a $25,000 contractor's bond on file with CSLB. That amount took effect January 1, 2023, under Senate Bill 607. CSLB describes the bond as protection for consumers damaged by defective construction or other license law violations, and for employees who were not paid wages owed to them.

What it can and cannot do for you. If you are harmed by an installer's license law violation, you can file a claim against the bond. Claims go directly to the surety company, which you can find through the Contractor's Bond History link on the contractor's license detail page. CSLB does not process bond claims; it handles license complaints separately.

Why the status matters. CSLB suspends a license if the bond is canceled and no replacement arrives within 30 days of the cancellation notice, or if claims reduce the bond below the required amount. CSLB warns that any work done while a license is suspended is considered unlicensed.

How to check an installer before you sign:

Step 1: Ask for the company's license number. It should be on the quote and contract.

Step 2: Look it up on the CSLB website. Confirm the business name matches, the license is active, and the classification fits the work.

Step 3: Check the bond section and the Contractor's Bond History link to see that a current bond is on file.

Step 4: If anything looks off, such as a suspended license or a different business name, ask the installer to explain before you sign or pay a deposit.

This is general information. For a dispute, contact CSLB or an attorney.

Today's next step: look up the license number on every quote you have before choosing an installer.
