What Happened to Kosmos Solar? A Guide for Abandoned Customers

Feel like you were promised the moon and stars, and now left stranded on the ground? …What about when that promise involved a major investment in solar panels for your home?

If you were a customer of Kosmos Solar, that feeling is probably all too familiar. You put your trust in a local company that promised quality service and long-term support, but they have since closed their doors, leaving you with an unsupported system and a lot of worries. 🙂

When the company you paid thousands of dollars to suddenly vanishes, it’s natural to feel angry, frustrated, and unsure of what to do next.

My hope and thought is that you can find a clear path forward, even when the original company is gone. And you definitely don’t have to accept being stuck paying for a system that’s broken, underperforming, or was never even finished.

The warranty and service promises made to you were a key part of the deal you signed. Just because Kosmos Solar is no longer around doesn’t mean you’re out of options. In fact, powerful consumer protection laws became designed for this exact scenario.

Ready to understand what happened with Kosmos Solar and what steps you can take to protect yourself? This post will (hopefully) walk you through everything you need to know, from their history of complaints to the legal action you can take today. Let’s begin!

A Look at Kosmos Solar’s History

Based in North Richland Hills, Kosmos Solar served the Dallas-Fort Worth area and other parts of Texas for several years. They positioned themselves as a reputable local installer, handling everything from residential to commercial solar projects.

The company was a significant player in the North Texas solar scene, completing many installations and building a substantial customer base. However, beneath the surface, a pattern of serious operational issues was developing that would ultimately lead to their failure.

The Warning Signs: A Pattern of Customer Complaints

Even while they were still in business, customer review sites like the Better Business Bureau (BBB) and Yelp were accumulating a growing number of serious complaints. These red flags pointed to a company that was struggling to meet its obligations.

Common issues reported by Kosmos Solar customers included:

• Abandoned Projects: Many customers paid large deposits, only to have the company stop work and cease all communication, leaving them with unfinished and non-operational systems.
• Poor Installation Quality: Some homeowners reported shoddy workmanship that led to property damage, including roof leaks.
• Inability to Get Service: A major complaint was the company’s failure to honor its warranty. Customers with broken or underperforming systems found it impossible to get Kosmos to send a technician for repairs.
• Non-Existent Communication: The most frequent complaint was a total lack of communication. Calls, texts, and emails went unanswered, leaving customers feeling completely abandoned. I know I’ve personally seen this is one of the most common signs that a solar company is about to collapse.

The BBB gives Kosmos Solar an “F” rating and notes a clear pattern of unanswered customer complaints.

What Went Wrong: An Abrupt Shutdown

Sometime in 2023, Kosmos Solar appears to have ceased all operations. The company didn’t make a formal announcement or file for a high-profile bankruptcy. They simply shut down.

Phones disconnected, offices closed, and the company walked away from its responsibilities. This left countless customers in a terrible position—some with unfinished projects, others with systems that failed shortly after installation, and all of them without the warranty they were promised.

Is Kosmos Solar Still in Business?

No. Kosmos Solar is permanently out of business. The company has been marked as “Permanently Closed” on review sites, and the BBB has confirmed that it is no longer in operation. There is no one left to call for help or to honor the commitments they made to their customers.

The Big Question: What About Your Warranty?

Kosmos Solar sold systems with the promise of long-term warranty coverage. Now that they are gone, it’s essential to understand what, if any, of that warranty remains.

1. Workmanship Warranty: This warranty covered the installation labor (wiring, mounting, etc.) and was provided by Kosmos Solar. Since the company no longer exists, this warranty is now completely worthless.
2. Manufacturer’s Warranty: This warranty covers the physical solar equipment like your panels and inverters. This coverage is provided by the manufacturer of the parts and is still valid. If you have a defective piece of equipment, you can and should file a claim directly with the manufacturer.

Your Most Important Legal Tool: The FTC Holder Rule

This is the most critical piece of information for any former Kosmos Solar customer who financed their system. You have a powerful legal protection called the FTC Holder Rule.

So…what is the Holder Rule?

This federal law is designed to protect consumers in situations just like this. It states that the lender who holds your loan is subject to the same legal claims and defenses you could have asserted against the seller (Kosmos Solar). In simple terms, because Kosmos breached its contract by failing to provide a working system or a valid warranty, you can hold your lender legally accountable for that failure.

This powerful consumer right means you may be able to:

• Bring a legal claim directly against the finance company that holds your loan.
• Stop making payments on a loan for an abandoned or broken solar system.
• Seek to have your entire loan canceled and get a refund for the payments you’ve already made.

The Holder Rule prevents a finance company from saying, “That’s not our problem,” when the seller they worked with fails.

Legal Actions to Take When Your Solar System Isn’t Working

If you are a former Kosmos Solar customer, you are not without options. You can take concrete steps to protect yourself.

1. Gather Your Paperwork. Collect your contract with Kosmos Solar, any project plans, and, most importantly, your loan and financing agreements.
2. Document the Problems. Take clear photos and videos of your unfinished or faulty system. Get a written quote from a reputable, independent solar company detailing the cost to complete or repair the work.
3. Notify Your Lender in Writing. Send a formal letter or email to your finance company. State that Kosmos Solar is out of business and has breached its contract. Inform them that you are asserting your rights under the FTC Holder Rule.
4. Consult with an Experienced Consumer Law Attorney. The most effective way to enforce your rights against a lender is to have professional legal representation. An attorney with experience in solar lawsuits can manage the entire process and fight to get you the remedy you deserve.

Frequently Ask Questions (FAQs)

Who can finish or fix my solar installation now?

You will need to hire another local, licensed solar contractor to complete or repair your system. You will have to pay for this work, but the cost can be included as part of your financial damages in a legal claim against your lender.

How do I find out who manufactured my solar panels?

The brand names of your solar panels and inverters should be listed in your contract documents from Kosmos Solar. You can then go to the manufacturer’s website to find their warranty information.

What’s the difference between a workmanship and a manufacturer warranty?

A manufacturer warranty covers defects in the product itself. A workmanship warranty covers the quality of the labor used to install it. The workmanship warranty from Kosmos is now void.

How do I find out who my lender is?

Your lender is the company to whom you make your monthly payments. Their name will be on your loan agreement and on your monthly billing statements.

Why is it important to have a lawyer for a Holder Rule claim?

Finance companies are large, powerful institutions that often try to deny their responsibility under the Holder Rule. An experienced attorney knows how to build a strong case, counter their arguments, and, if necessary, take them to court to enforce your rights.
