A June 2026 Harvard Business School analysis reported that roughly 100 U.S. solar companies have filed for bankruptcy since 2023 — including SunPower, Sunnova, Mosaic, Titan Solar Power, and Freedom Forever. For real estate professionals, this is no longer an industry-news curiosity. It's a closing-table problem. With more than 5 million U.S. solar installations and third-party ownership now covering over half the residential market, the odds that one of your listings has solar from a company that no longer exists are rising fast. This guide gives you the pre-listing due diligence that keeps a solar system from stalling your escrow, spooking your buyer, or landing on your errors-and-omissions exposure.
Why the shakeout is your problem now
When a solar company fails, the panels stay on the roof — but the paperwork that makes them transferable can quietly break. The HBS analysis put it bluntly: because solar financing is often tied to the home, borrowers "may face liens that complicate refinancing or selling their property," turning an energy decision into a housing risk. That risk lands on your desk the moment you take a solar listing.
The scale is what's new. U.S. residential installs topped 5 million, third-party ownership (leases and PPAs) grew from 40% to 52% of the market in a single year, and the failures now include the biggest financiers and installers in the country. A meaningful share of the solar homes coming to market this year and next were sold, financed, or serviced by a company that has since gone under.
The five ways a failed solar company kills a deal
| Risk | What happens at closing |
|---|---|
| Undisclosed UCC-1 lien | Title turns up a fixture filing on the equipment; escrow can't close until it's cleared or the payoff/holder is identified. With the original lender bankrupt, finding the successor takes time. |
| Unassignable lease / PPA | Buyer must qualify for and assume the agreement; the servicer (often a post-bankruptcy successor) has to approve. Miss it early and it becomes a contingency scramble. |
| Open / unfinaled permit | The installer went under mid-project or never closed the permit. An open permit can block a sale or trigger lender conditions. |
| Net-metering that doesn't transfer | A grandfathered rate worth thousands per year may not pass to the buyer — a value and disclosure issue if the listing implied "low electric bills." |
| Stranded workmanship warranty | Buyer asks "who services this?" and the honest answer is "the company that installed it no longer exists." Without a plan, that kills buyer confidence. |
Each of these is fixable — but only if you find it before you list, not during a 10-day inspection window. For the mechanics of what to do when solar is holding up a closing, see solar is holding up my closing and solar problems after closing: an agent's guide.
The pre-listing due-diligence checklist
Run this on every solar listing, ideally at the listing appointment:
- Determine ownership. Owned outright, financed with a loan, or third-party owned (lease/PPA)? This single answer drives everything else.
- Identify the installer and its status. Is it still operating, acquired, in Chapter 11, or gone? Get the name off the permit or interconnection paperwork, then check.
- Search for a UCC-1 fixture filing. Check the state's Secretary of State UCC database against the seller's name. Identify the secured party and, if it's a failed company, the current payoff holder. See solar UCC liens & title.
- Confirm permit status. Verify the solar permit was finaled with the local jurisdiction. See open solar permits at closing.
- Check for a PACE lien. Some systems were financed through property-assessed clean energy programs that attach to the tax bill. See PACE liens at closing.
- Establish net-metering transferability. Confirm whether the grandfathered rate passes to the buyer in your state and utility. See net-metering transfer at resale.
- Locate the financing servicer. For a loan or lease, identify who currently services it and start any transfer or payoff request early.
- Document the equipment and warranties. Panel, inverter, and battery makes and models — and which manufacturer warranties remain, independent of the installer.
A SolarDisclosure™ closing report pulls the installer status, UCC and PACE liens with payoff holders, permit status, financing servicer, equipment warranties, and net-metering transferability into one document you can hand to title, the seller, and the buyer.

Owned outright
Lowest risk, but not zero. Still check for a UCC filing (some cash-plus-loan systems have one), confirm the permit was finaled, and document equipment warranties so the buyer knows what's covered. A failed installer here mainly means "no workmanship service," which you can address with a local servicing contractor. See our owned-solar value guide.
Solar loan
The loan is almost always held by a lender, not the installer — so even a bankrupt installer usually doesn't touch the financing. The lien and payoff are the closing issues. If the lender itself failed (e.g., Mosaic), the loan and lien were transferred; identify the successor servicer for an accurate payoff. See finding solar financing before an offer.
Lease or PPA (third-party owned)
Highest complexity, and now the most common. The panels belong to a third party; the buyer must assume the agreement or the seller must buy it out. If the lease company went bankrupt, the transfer runs through a successor servicer — start it the day you list. See solar leases at closing and what happens to a solar lease when the company goes bankrupt.
What to say to sellers and buyers
To a seller at the listing appointment: "About 100 solar companies have gone bankrupt since 2023, so buyers and their lenders are scrutinizing solar homes more than they used to. Let's document your system now — the lien, the permit, who services it, and how the net-metering transfers — so it's a selling point instead of a question mark. It also protects you from a price renegotiation later."
To a buyer or buyer's agent: "Yes, the installer is no longer in business. Here's the documentation: the equipment warranties are with the manufacturers and remain valid, the permit is finaled, the lien payoff is identified, and here's who services the system going forward." That turns the single most common objection into a closed loop.
Protecting yourself and your commission
Undisclosed solar issues are a disclosure-and-liability exposure, not just a deal-speed problem. Agents have been drawn into post-closing disputes over liens a buyer didn't know about and net-metering savings that didn't materialize. The protection is simple and it's the same in every case: document the system in writing before you list, and put that documentation in the buyer's hands. A disclosure report is inexpensive relative to a stalled escrow, a renegotiated price, or an E&O claim — and it's a differentiator when you win the listing.
Frequently asked questions
The installer is bankrupt. Can we still sell the home?
Yes. A bankrupt installer doesn't stop a sale. What matters is the paperwork: clearing any lien, confirming the permit is finaled, arranging lease/loan transfer or payoff, and documenting warranties. Handle those and the system becomes a straightforward part of the transaction.
How do I find out who now holds the loan or lease if the company failed?
Start with the seller's most recent statement, then trace the successor servicer named in the bankruptcy. A UCC search identifies the secured party of record. A SolarDisclosure™ report does this trace for you and returns the current payoff holder.
Do buyers really care that the installer is gone?
They care about service and cost, not the installer's corporate status. When you can show the equipment warranties are intact, the permit is closed, and there's a plan for future service, the objection disappears. Silence is what kills confidence.
Document the solar before you list
One SolarDisclosure™ report covers installer status, UCC and PACE liens with payoff holders, permit status, servicer, warranties, and net-metering transferability — the whole checklist, in a document you can hand to title and the buyer.
