When Solar Panel Agreements Go Wrong: The Lien Problem

In a separate article, we explained why it is important to be cautious before signing a solar panel contract. But what happens if you have already signed and then stop making payments?

The answer depends heavily on what type of lien has been filed as a result of that agreement. Solar panel disputes in Arizona can involve a mechanic’s lien, a standard UCC-1 financing statement, or a fixture filing. Each type of lien is distinct and the variations between them may result in different outcomes.

Before going any further – it is worth noting that this article assumes the solar company has performed as the written contract requires (even if the sales pitch promised more than the agreement delivered). If the agreement was breached by the contractor or the lender then the dispute would follow the resolution procedures spelled out in the signed agreement. This article considers the situation where there was no determination of a breach by the solar company, but the homeowner does not pay the required amount.

The first thing to consider is the nature of the lien. A solar agreement could result in a Mechanic’s Lien or a UCC-1 Lien.

Mechanic’s Liens (Lien Against the Home Itself)

A solar panel company can file a mechanic’s lien against the home if it is not paid for installation work or materials. This type of lien:

  • Attaches directly to the home itself (not just the panels).
  • Can give the company the right to pursue foreclosure of the home if unpaid.
  • Requires the contractor to be properly licensed and to follow Arizona’s notice and filing rules.

Mechanic’s liens usually arise only if the installer or its subcontractors have not been paid. These liens must be filed within 120 days of when the installation work is completed. If a finance company already paid the installer, a mechanic’s lien is unlikely.

As such, the balance of this article will focus on the impact of what is known as a UCC-1 lien.  Just be aware, If a mechanic’s lien exists the options available to the lienholder are even more powerful.

UCC-1 Liens (Most Common in Solar Financing)

Most solar loans or leases result in a UCC-1 financing statement, not a mechanic’s lien. A UCC-1 (“Uniform Commercial Code” ) filing is a public notice that a lender has a lien or security interest in specific property, such as solar panels.  These liens secure the solar panels themselves rather than the entire property.

But there are two variations of UCC-1 liens:

Standard UCC-1 Filing

  • Filed with the Arizona Secretary of State.
  • Covers the panels and related equipment as personal property.
  • May not automatically show in county title searches, but can still cloud title.
  • Title and escrow companies often require releases before a home can be sold or refinanced.

Fixture Filing (Special UCC-1)

  • A type of UCC-1 filed in county land records, with the property’s legal description.
  • Declares the panels “fixtures” attached to the home.
  • Appears prominently in a title search—treated much like a lien on the property.

In both standard and fixture filings, the lien gives the lender rights in the panels. The difference is mainly in visibility.  Either type can and likely will have an impact on real estate transactions: fixture filings integrate directly into the property’s title history, while standard UCC-1s are tracked at the state level.

The Lender’s Enforcement Options

Once a UCC-1 lien exists, the lender controls which enforcement path to take if they are not paid per the terms of the agreement:

Repossession of the panels

  • In theory, the lender can remove the panels which may be done to penalize the home owner, to allow a contractor to re-use the panels or to potentially re-sell the panels.
  • In practice, repossession is rarely pursued because:
    • Used solar panels have little resale value.
    • Removal is expensive and can damage the roof.
    • The process is logistically difficult and often not worth the cost.
  • The lender may then sue for the remaining balance (deficiency) and damages, just like after a car repossession.

Lawsuit without repossession

  • More commonly, the lender skips repossession
  • They leave the panels in place, keep the lien active, and file a lawsuit for the full unpaid balance.
  • This usually results in a money judgment plus a lien that clouds title until released.

The borrower has no power to force repossession. The lender decides which remedy to pursue, and most lenders choose the lawsuit path.

The Role of Bankruptcy

Bankruptcy can help, but only to a point:

  • What bankruptcy can do:
    • Discharge the borrower’s personal liability for the debt, whether from repossession (deficiency balance) or a lawsuit without repossession.
    • Prevent wage garnishment, bank levies, and other collection on the judgment.
  • What bankruptcy cannot do:
    • Remove the UCC-1 lien if the panels were not repossessed.
    • The lien remains on record even after bankruptcy, creating ongoing issues.

The Lingering Impact of the Lien

A UCC-1 lien that is not cleared can cause long-term headaches:

  • Sale of the home – Title companies usually require the lien to be satisfied before closing.
  • Refinancing – Lenders won’t refinance with an active lien on record.
  • Estate transfers – A lien can block the property from being smoothly transferred to heirs.

Because many lenders prefer lawsuits over repossession, these liens often sit for years. Bankruptcy may wipe out the personal obligation, but the lien itself is a problem that almost always resurfaces later.

The Takeaway

If payments stop, the lender—not the borrower—chooses the remedy. Bankruptcy can protect against personal collection, but it does not erase the lien unless repossession occurs. For most homeowners, the bigger issue is not the lawsuit or even repossession, but the long-term effect of a lingering UCC-1 lien on their property.

Early negotiation with the lender is often the best chance to resolve the debt before it grows into a lawsuit, judgment, and years of title complications.
