How to Verify a Solar Contractor's Licence Before You Sign
By Seamless Home Team, Solar fulfillment operations · August 14, 2026
Quick answer
Ask for the licence number and the exact legal name of the contracting entity, then look both up on your state's contractor licensing board website, which is free and public. Confirm the licence is active, that it is held by the same legal entity named on your contract, that its classification covers the work, and that any bonding or insurance the state requires is current. Also check whether there are complaints or disciplinary actions on the record. If the name on the licence does not match the name on the contract, resolve that before signing rather than after.
A licence number printed on a contract proves that somebody typed a licence number onto a contract. It does not prove the licence is active, that it belongs to the company in front of you, or that it covers the work being sold.
Checking properly is free, public and takes roughly ten minutes. It is the highest-value ten minutes in the entire process of buying PV solar.
What to ask for first
Before you can check anything you need two pieces of information, and you are entitled to both:
- The licence number.
- The exact legal name of the entity you would be contracting with, not the brand on the van or the letterhead, but the legal entity in the contract's party block.
Those two frequently differ, and the difference is the point. A company may trade under one name and hold its licence under another; a sales organisation may be a separate entity from the licensed contractor that will perform the work.
A contractor who is reluctant to give you either of these has told you something useful.
The lookup itself
Every state maintains a contractor licensing authority, and nearly all publish a free public search. Search for your state's contractor licensing board, then look up either the number or the legal name.
Some states also license at city or county level for certain trades, so if the state record looks thin for the work involved, check locally as well.
What to confirm on the record
| Check | What you are looking for | Why it matters |
|---|---|---|
| Status | Active, not expired, suspended or revoked | An inactive licence cannot lawfully pull your permit |
| Legal entity | Exactly matches the name on your contract | If they differ, you may be contracting with an unlicensed party |
| Classification | Covers PV solar, electrical or the relevant trade | A licence for unrelated work does not cover your installation |
| Expiry date | Comfortably beyond your install date | A licence expiring mid-project is a scheduling risk |
| Bond and insurance | On file where the state requires it | Your recourse if something goes wrong |
| Disciplinary history | Complaints, citations, actions | Pattern matters more than any single item |
Reading the disciplinary history sensibly
This is where people either over-react or skip the section entirely.
A contractor that has been trading for fifteen years and has one resolved complaint is not a warning. Construction generates disputes; a resolved one shows the system working.
What to look at instead:
- Frequency relative to time in business. Several complaints in two years is a different signal from several across fifteen.
- Whether they were resolved, and how.
- Whether they concern the work you are buying. Workmanship claims about roof penetrations are directly relevant to a roof-mounted PV solar array. A billing dispute is less so.
- How recent they are. Recent problems say more about the company today than old ones.
Insurance, separately
The licence record may show whether a bond is on file, but general liability and workers' compensation are usually separate.
Ask for a certificate of insurance, and check the dates on it. A certificate from two years ago tells you the contractor was insured two years ago.
Workers' compensation matters more than people expect. If an uninsured worker is injured on your property, the question of who is responsible can become your problem.
What to do if something does not check out
Licence expired or inactive. Do not proceed. This is not a paperwork technicality. The permit cannot lawfully be pulled against it.
Name mismatch. Ask which entity will be the contractor of record, get the answer in writing, and verify that entity's licence.
Classification does not obviously cover the work. Ask how the work is classified in your state. There may be a good answer; there may not.
No record at all. Confirm you have the correct number and state first, because transcription errors are common. If there is genuinely no record, that is decisive.
A pattern of unresolved workmanship complaints. You have other options.
Why this matters more in PV solar than in most trades
Two features of residential PV solar make the check unusually worthwhile.
First, the selling company and the installing company are often different, more so than in most home improvements. That separation is lawful and often sensible, but it means the entity you build a relationship with may not be the entity responsible for the work. See who is the contractor of record.
Second, the warranty that matters most is a promise from a specific company. Equipment warranties come from manufacturers and generally survive whatever happens to the installer. The workmanship warranty, the one covering roof penetrations, mounting and wiring, is only as durable as the company that issued it. That is covered in who stands behind a solar installation warranty.
Checking that the licensed entity is real, active and identifiable is the closest thing to a guarantee that there will be somebody to call.
A ten-minute checklist
- Ask for the licence number and the exact legal entity name.
- Look both up on your state's contractor licensing board site.
- Confirm the licence is active and unexpired.
- Confirm the entity name matches your contract.
- Confirm the classification covers the work.
- Check bond and insurance are current; ask for a certificate of insurance.
- Read the disciplinary history, weighing pattern over any single item.
- Confirm in writing who will pull the permit and who owes the workmanship warranty.
- Do all of the above before signing or paying a deposit.
The bottom line
The check costs nothing, takes ten minutes, and is the single most informative thing you can do before signing a PV solar contract.
The most common finding is not fraud. It is a mismatch between the company selling and the company that will be responsible, which is often a perfectly legitimate structure that simply needed explaining. Asking the question early gets it explained while you still have every option open.

Frequently asked questions
How do I check if a solar contractor is licensed?
Search your state's contractor licensing board website for the licence number or the company's legal name. Most states publish a free public lookup showing whether the licence is active, what classifications it covers, when it expires, the qualifying individual behind it, and whether there is any disciplinary history. If your state licenses at city or county level for some work, check there too.
What should the licence lookup tell me?
At minimum whether the licence is active and unexpired, the exact legal entity that holds it, the classification or trade it covers, and whether bonding and workers' compensation coverage are on file where the state requires them. Many states also show complaint and disciplinary history, which is worth reading rather than skimming.
The licence is under a different name than the company I am talking to. Is that a problem?
It needs explaining before you sign. There can be legitimate reasons: a company operating under a trading name, or a sales organisation working with a separately licensed contractor who will perform the installation. What you need is a clear account of which entity is which, and confirmation that the licensed entity is the one that will pull the permit and be responsible for the work.
Does a solar contractor need a special licence?
It depends on the state. Some issue a specific solar or photovoltaic classification, others cover the work under a general, electrical or specialty contractor licence. Electrical work often requires its own licensed party regardless. The point is not which category applies but whether the classification the contractor holds actually covers the work being done.
Should I check insurance and bonding as well?
Yes. Ask for a certificate of insurance naming general liability and workers' compensation, and confirm the coverage is current rather than expired. Where your state requires a contractor bond, the licence record usually shows whether it is on file. Insurance matters because an uninsured crew working on your roof can leave you exposed if someone is injured.
What if I find complaints against the contractor?
Read what they are before drawing a conclusion. A single resolved complaint over many years of trading is different from a pattern of unresolved workmanship claims. Look at how recent they are, whether they were resolved, and whether they concern the kind of work you are buying. A pattern is a reason to look elsewhere; one old resolved item usually is not.
When should I do this check?
Before signing, and before paying any deposit. The check is free and takes about ten minutes. Doing it afterwards still tells you something useful, but it removes your best option, which is simply choosing a different contractor.
