Does a Solar Installer Need General Liability and Workers’ Comp Insurance? A Buyer-Side Vetting Checklist

General Liability Is a Licensing Gate, Not a Nice-to-Have

General liability insurance, commonly at a minimum of $1 million in coverage, is a baseline contractor-licensing requirement in most states, and contractor licensing boards typically require proof of active general liability coverage, often alongside a surety bond, as a condition of issuing or renewing a solar or electrical contractor license. That means whether an installer carries general liability insurance is not something a homeowner has to take on faith, it is directly checkable against the installer’s actual license status with the state licensing board.

A rep or homeowner who wants a real answer, rather than a verbal assurance, can confirm this the same way a licensing board would: by looking up the installer’s license and confirming its status is active and in good standing, since a lapsed or suspended license is the clearest sign the underlying insurance requirement is not currently being met.

Workers’ Compensation Is Mandatory Almost Everywhere, With Two Named Exceptions

Workers’ compensation coverage is legally mandatory in most states for any contractor with employees, and it is directly tied to license issuance and renewal in most of those states. Oklahoma and Texas are the two states most commonly cited as elective, meaning a business operating there is not required by state law to carry workers’ comp. That is an important, specific exception for a buyer-side checklist to name rather than assume away, since a homeowner in one of those two states cannot rely on licensing status alone to confirm coverage exists.

Outside Oklahoma and Texas, the same logic that applies to general liability applies here: an active contractor license is meaningful evidence that workers’ comp requirements are being met, because most state licensing boards will not renew a license without it.

What Is at Stake for the Homeowner Without Coverage

General liability specifically covers third-party bodily-injury and property-damage claims arising from the job, a worker damaging the roof, a fall causing injury on the homeowner’s property, plus the installer’s legal defense costs for those claims. Without it, a homeowner can be left directly exposed to liability or an uncompensated damage claim if an accident happens during their own installation. That is the concrete “why this matters” behind a checklist that might otherwise read as a formality: the coverage is what stands between the homeowner and paying out of pocket for an accident that was not their fault.

Workers’ compensation protects a different party in the same accident: the worker themselves. A crew member injured on a job without workers’ comp coverage can, depending on the state, pursue a personal-injury claim against whoever is on the property, which in some circumstances can reach the homeowner rather than staying contained to the contractor.

A Buyer-Side Checklist to Run Before Signing

• Ask for the installer’s state contractor license number and confirm its status directly with the state licensing board, not from the installer’s own paperwork alone.
• Ask for a certificate of insurance naming general liability coverage of at least $1 million, and confirm it is currently active, not expired.
• If the property is in Oklahoma or Texas, ask specifically whether the installer carries workers’ compensation coverage, since it is not a mandatory requirement in either state.
• Confirm whether any subcontractors on the job, electrical, racking, or otherwise, carry their own coverage or fall under the general contractor’s policy.

Four questions, asked before a contract is signed, are enough to move this from a trust-me claim to something a homeowner can independently verify.
