How to Check a Solar Installer’s License and Insurance
Use a practical checklist to verify a solar installer’s public license, insurance, scope, subcontractors, warranties, and current contact information.
Quick answer
Verify an installer through the relevant state or local licensing authority, request current insurance details, and make sure the company named in the contract matches the company performing the work.
Use the official license lookup
Search the responsible contractor-licensing authority using the company’s legal name and license number. Confirm the license status and classification are appropriate for the proposed scope.
Ask about insurance and subcontractors
Request current insurance information and ask whether electrical, roofing, or installation work will be subcontracted. The contract should identify who is responsible for each part of the project.
Match paperwork to the actual company
The salesperson’s brand, contract counterparty, permit applicant, and installer can be different entities. Keep records showing who sells, installs, warranties, and services the system.
Check the support path
Ask who handles monitoring, warranty claims, roof issues, and future service. A good proposal gives you a clear contact path after installation, not only a sales number.
