You signed a contract, the panels went up, and eighteen months later the phone number on your invoice is disconnected. Top Solar Services is a directory that vets solar contractors by license status, insurance, and verified customer reviews before listing them, and one of the most common questions homeowners bring us is what to do when the company they hired is simply gone. A closed installer cannot honor a workmanship warranty, cannot answer a monitoring-app alert, and cannot show up for a repair truck roll. Solar installer insolvency is the situation where the company that sold, financed, or installed your system stops operating, leaving the manufacturer warranties on the equipment as your only remaining protection.

The good news is that a closed installer does not usually mean a dead system. The bad news is that finding out what still applies, and who is now responsible for it, takes real work that most homeowners never expected to do.

How Common Is It for Solar Installers to Go Out of Business?

Residential solar has gone through several rounds of consolidation as financing costs rose and the federal residential solar tax credit under Section 25D expired on December 31, 2025. Regional and national installers have closed, merged, or exited residential work entirely during past downturns, and smaller local shops with thin cash reserves are especially exposed when a slow permitting season or a financing partner pulling out stretches their payroll. None of this means solar itself is a bad investment; it means the installer you hire is a separate risk from the equipment on your roof, and the two need to be evaluated separately.

What Happens to Your Warranty When the Installer Closes?

A residential solar system carries three separate warranties, and they do not all end when the installer does. The table below shows who remains on the hook for each one.

The workmanship warranty is the one that disappears, and it is the warranty that covers roof leaks at the mounting points, wiring errors, and labor for any repair. Losing it means you now pay a new contractor's hourly rate for anything that is not a defective part covered by the manufacturer.

How Do You Check an Installer's Stability Before You Sign?

You cannot see a company's bank balance, but several public signals correlate with how likely it is to still be around in five years.

1. Look up the installer's state contractor license number and confirm it is active, not expired or suspended, on your state licensing board's website.
2. Check how long the license has been held under the current business name — a license transferred or reissued within the last year is a flag worth asking about directly.
3. Confirm the company carries at least $1 million in general liability insurance and current workers' compensation, and ask for a certificate naming your project address.
4. Ask whether the panel and inverter warranties are registered in the manufacturer's system under your name, not just the installer's dealer account, so you can file a claim directly if needed.
5. Call two or three of the installer's references from installs completed at least two years ago, not just recent ones — a company in trouble often still delivers a good first year.
6. Ask directly how the company would handle a warranty claim if it closed tomorrow, and get the answer in writing as part of the contract, not a verbal promise.

Doing that legwork for every quote you collect is tedious, which is exactly the point where most homeowners either skip it or hire the first company that returns a call. Top Solar Services checks state license status, insurance, and verified review history before a contractor is listed in our directory of vetted solar companies, so the stability screening is already done before you request a quote.

What Should You Do If Your Installer Already Closed?

Start with the paperwork, not a new sales call. Locate your original contract, the panel and inverter serial numbers, and any warranty registration confirmation emails. Contact the panel manufacturer and the inverter manufacturer directly — most have a support line for homeowners whose installer is no longer operating, and they can confirm whether your equipment is still registered under warranty. If your system uses a monitoring platform tied to the installer's dealer account, the manufacturer can often transfer that account to you directly once you verify ownership.

Once you know what is still covered, you need a new licensed installer for any future service call, since the closed company's workmanship warranty cannot be honored by anyone. Look for a contractor who has experience servicing systems they did not originally install — not every installer will take on someone else's wiring, and the ones who do usually charge a diagnostic fee for the first visit regardless of what they find.

Is It Worth Choosing a Cheaper, Newer Installer to Save Money?

A lower bid from a company that has been licensed for eight months is not automatically a bad choice — every installer was new once — but it does shift risk onto you in a way a ten-year-old company with a deep reference list does not. If the price gap is small, the stability signals above matter more than the discount. If the price gap is large, ask what is different about the equipment, the crew, or the overhead that lets them bid lower, and get that answer in writing before you sign. A written five-year or ten-year workmanship warranty is only worth as much as the company backing it is likely to still exist.

The U.S. Department of Energy's homeowner guide to going solar advises verifying installer credentials and getting multiple quotes before signing, precisely because the equipment usually outlasts the company that installed it. The North American Board of Certified Energy Practitioners maintains a public lookup at nabcep.org where you can confirm a specific installer's certification is current rather than expired.

What Should You Ask Before Signing a Solar Contract?

Beyond price and equipment brand, ask what happens to your workmanship warranty if the company is acquired, and whether that warranty transfers automatically or requires you to re-register. Ask whether the crew doing the physical installation is direct employees or a subcontracted crew, since a subcontractor relationship can end even if the parent company stays open. Our solar company FAQ page covers additional licensing and warranty questions worth reviewing alongside your specific contract.

None of this is a reason to delay going solar — it is a reason to spend the same hour you would spend comparing panel brands on comparing the company standing behind them. A system installed by a company that closes in year three still saves you money for the next twenty-two years; you simply lose the free labor for anything that goes wrong.
