Ever feel like you’re trying to hit a moving target? …What if that target is the company responsible for the solar panels on your roof?

If you started your solar journey with Zenith Solar, you’ve been on a wild ride. Your account has been passed through a dizzying chain of companies: first Zenith was acquired by Deca, which was then absorbed into Lumio. Now, Lumio has filed for bankruptcy, leaving you to wonder who, if anyone, is left to stand behind your investment. 🙂

When you’re facing a problem with your system and the company name on your contract has changed three times, it’s completely normal to feel lost and frustrated.

My hope and thought is that you can find a clear path forward through this corporate mess. And you definitely don’t have to feel abandoned just because the companies you dealt with have disappeared.

When you were promised decades of support and warranty coverage, that promise should not vanish with a bankruptcy filing. The good news is, there are powerful consumer protection laws designed for this exact situation.

Ready to untangle the Zenith-Deca-Lumio story and learn how to protect yourself? This post will (hopefully) walk you through everything you need to know, from the chain of acquisitions to the legal actions you can take today. Let’s get started!

A Tangled Web: Zenith Solar Corporate History

Understanding your situation starts with tracing the convoluted path of your account. It likely followed these steps:

  1. Zenith Solar: This is the company you may have originally signed with. They operated as a solar sales and installation company. 
  2. Acquired by Deca Solar: Zenith was later acquired by Deca Solar, and your account might have been transferred to Deca. Or you may have originally signed up with Deca depending on the installer listed on your contract. 
  3. Merged into Lumio: In 2021, Deca Solar was one of several large solar companies that merged to create a new national entity called Lumio. At this point, your warranty and service obligations may have been transferred again, this time to Lumio.

For years, Lumio was one of the largest and fastest-growing solar installers in the country. But that growth was not sustainable.

The Customer Experience: Lost in the Shuffle

Even before the final collapse, customers in this chain of companies often reported feeling lost. On review sites like the Better Business Bureau (BBB), complaints frequently cited confusion and a lack of support.

Common issues included:

  • Poor Communication: Customers struggled to get answers as their accounts were passed from one company to the next.
  • Service and Warranty Issues: Getting service for a system installed by Zenith or Deca became increasingly difficult under Lumio’s management.
  • Blame Game: When problems arose, it was often unclear which entity was responsible, leaving homeowners stuck in the middle. I know I’ve personally seen how these corporate shells games can be a nightmare for consumers.

What Went Wrong: The Lumio Bankruptcy

The instability culminated in June 2024, when Lumio abruptly ceased operations and filed for Chapter 7 bankruptcy.

This is the most critical fact for you to understand. A Chapter 7 bankruptcy is not a reorganization; it is a liquidation. This means Lumio is shutting down permanently. The company is selling all its assets to pay its debts, and it will not be completing any projects, servicing any systems, or honoring any warranties.

The company that held your warranty obligation has been legally dissolved.

Are They Still in Business? The Final Answer

No. According to the information that we have been able to find, Zenith Solar, Deca Solar, and Lumio are all believed to be out of business. (Updated 10/31/25)

You may have heard that another company, Suntuity Renewables, “took over” Lumio’s accounts. It is crucial to understand what this means. Suntuity acquired Lumio’s customer list out of the bankruptcy, but they did not acquire the company itself or its legal liabilities. This means Suntuity has no legal obligation to honor the workmanship warranty you received from Zenith, Deca, or Lumio.

The Million-Dollar Question: What About Your Warranty?

Your solar system came with two primary warranties. Here’s where they stand now:

  1. Workmanship Warranty: This covered the installation labor and was held by Lumio at the time of bankruptcy. Because Lumio was liquidated, this warranty is now void. There is no company left to honor it.
  2. Manufacturer’s Warranty: This covers the physical hardware (your panels and inverters). This warranty is provided by the equipment manufacturer and is still valid. You can and should file claims directly with the manufacturer for any defective parts.

Your Strongest Legal Shield: The FTC Holder Rule

This is the most important part of this entire article. Just because the installers are gone does not mean you are out of options. If you financed your solar system, you are protected by a federal law called the FTC Holder Rule.

So…what is the Holder Rule?

The Holder Rule states that the company that holds your loan is subject to the same legal claims you could have asserted against the seller. Since Lumio (the final seller) breached your contract by failing to provide a lasting 25-year warranty, you can now hold the finance company that holds your loan legally responsible for this failure.

This powerful protection means you may be able to:

  • File a legal claim directly against your lender for the full value of your non-supported system.
  • You may be able to challenge the validity or enforceability of the loan if the system was misrepresented.
  • Seek to have your loan balance canceled entirely and get a refund for payments already made.

This rule was created to protect consumers from being left with a debt for a failed product or service.

Legal Steps for Former Zenith, Deca, and Lumio Customers

If you are one of the thousands of homeowners caught in this situation, it’s time to take action.

  1. Gather All Your Documents. Find your original contract (whether it says Zenith, Deca, or Lumio) and, most importantly, your loan and financing agreements.
  2. Document All Problems. If your system is failing, take pictures and videos. Get a quote from an independent solar technician for any necessary repairs. This will serve as evidence of your damages.
  3. Notify Your Lender in Writing. Send a formal letter or email to your finance company. State that Lumio has filed for Chapter 7 bankruptcy and has breached its warranty contract. Inform them that you are asserting your consumer rights under the FTC Holder Rule.
  4. Consult with an Experienced Consumer Law Attorney. A law firm that is experienced in handling solar panel and Holder Rule cases is your most effective ally. They can navigate the complex legal process of filing a claim against a large financial institution on your behalf.

Zenith Solar Conclusion

The journey from Zenith Solar to the Lumio bankruptcy is a textbook example of the instability in the residential solar industry. The constant mergers and acquisitions created a house of cards that ultimately collapsed, leaving countless homeowners with unsupported systems and voided warranties.

However, the final chapter is not yet written for you. You are not simply a victim of corporate failure; you are a consumer with powerful legal rights. The FTC Holder Rule provides a direct path to hold your lender accountable for the broken promises of the sellers.

Above all, remember that you are not stuck. By taking informed and decisive action, you can protect yourself from a devastating financial loss and work towards a just resolution.

Zenith Solar FAQs

Who do I call for service on my solar panels now?

You will need to contact a local, independent solar repair company. You will have to pay for this service yourself, but these costs can be included as part of the damages in a legal claim against your lender.

Will Suntuity honor my Lumio warranty?

It is highly unlikely. Suntuity purchased a customer list, not Lumio’s legal obligations. You should not expect them to provide free warranty service for a system installed by a different, now-bankrupt company.

How do I find out who the manufacturer of my solar panels is?

The brand and model of your panels and inverters should be listed in your original contract documents. You can then visit that manufacturer’s website to initiate a warranty claim for faulty equipment.

What is the difference between Chapter 7 and Chapter 11 bankruptcy?

Chapter 11 is a reorganization, where a company tries to stay in business. Chapter 7, which is what Lumio filed, is a liquidation. It means the company is shutting down for good.

Why is it better to sue my lender instead of the solar company?

You cannot effectively sue a company that has been liquidated through Chapter 7 bankruptcy. There is nothing left to recover. Your lender, however, is a financially stable company that is legally subject to your claims under the Holder Rule.
