What Former ADT Solar Customers Need to Do After the Company's Closure

When homeowners invest in solar, they expect decades of clean energy production, lower utility bills, and ongoing support from their installer. Unfortunately, when a solar company shuts down, files for bankruptcy, or exits the market, customers can find themselves in a difficult situation known as becoming a solar orphan.

Many of the homeowners affected by ADT Solar's closure were originally Sunpro Solar customers. ADT acquired Sunpro Solar in 2021 and rebranded the company as ADT Solar, expanding its presence across numerous states. However, after ADT Solar shut down its residential solar business in 2024, thousands of homeowners, including both former ADT Solar and legacy Sunpro Solar customers—were left without their original installer for service, maintenance, and warranty support.

If you previously purchased a solar system from the company, this guide explains what it means to be a solar orphan, what support options remain available, and how you can protect your solar investment moving forward.

Common Problems ADT Solar Customers Experience

The absence of an original installer can make diagnosing and resolving solar system issues more difficult. Below are some of the most common problems customers may face.

Inverter Failures

If your inverter is experiencing problems, you may notice reduced solar production, error messages appearing on the inverter or monitoring app, monitoring systems showing the inverter as offline, or a complete loss of solar generation. These symptoms often indicate a malfunctioning inverter or a related communication or electrical issue that should be diagnosed promptly to prevent extended energy losses.

Many inverter manufacturers provide warranties ranging from 10 to 25 years, but homeowners need a qualified technician to diagnose the problem.

Monitoring System Issues

Former customers report difficulties accessing:

• Production data

• Consumption monitoring

• Mobile applications

• Historical performance reports

Monitoring interruptions can make it difficult to determine whether the system is functioning properly.

Roof Leak Concerns

Solar panels are secured to the roof using mounting systems that require roof penetrations. While properly installed systems are designed to remain watertight, leaks can occasionally develop years after installation due to aging materials, weather exposure, or installation-related issues. For customers, determining who is responsible for repairs can be particularly challenging when the original installer is no longer available.

If you notice water stains, moisture intrusion, or signs of a roof leak near your solar array, it is important to have the issue inspected by a qualified solar service provider. They should evaluate both the roofing components and the solar mounting hardware to identify the root cause and ensure repairs are completed without compromising the safety or performance of the solar system.

System Underperformance

A solar system producing less electricity than expected may result from:

• Equipment failures

• Damaged wiring

• Shading changes

• Dirty panels

• Inverter problems

• Communication failures

Without monitoring, many homeowners do not realize their systems are underperforming until utility bills increase.

For homeowners dealing with these challenges, understanding the status of their warranty coverage is often the next critical step.

Are ADT Solar Warranties Still Valid?

One of the most common concerns among  customers is warranty coverage. The answer depends on the type of warranty involved.

Manufacturer Warranties

In many cases, manufacturer warranties remain active even if the installer is no longer operating.

Examples include warranties from equipment manufacturers such as:

• Enphase Energy

• SolarEdge Technologies

• Tesla

• Qcells

• REC Group

These warranties generally remain in force because they are issued directly by the manufacturer rather than the installer.

However, homeowners often need an independent solar service company to diagnose issues and coordinate claims.

Workmanship Warranties

Workmanship warranties are more complicated. These warranties typically cover:

• Installation defects

• Roof penetrations

• Wiring issues

• Mounting system problems

If ADT Solar provided the workmanship warranty, coverage may no longer be available because the company that issued it no longer performs service work. This is often the biggest challenge for solar orphans.

Understanding your warranty status is only part of the solution. The next step is knowing how to obtain service, repairs, and ongoing support for your solar system. 

How to Get Help as a Former ADT Solar Customer

Step 1: Gather System Information

Before seeking service or warranty support, gather all available documentation related to your solar system. This should include your solar installation contract, warranty paperwork, equipment serial numbers, utility interconnection documents, and monitoring platform login credentials. Having these records readily available can make troubleshooting faster, simplify communication with manufacturers or service providers, and help expedite any warranty claims.

Step 2: Identify Your Equipment

Identifying the major components of your solar energy system is an important first step when seeking repairs, maintenance, or warranty support. Most residential solar installations consist of three primary equipment categories: solar panels, inverters, and, if applicable, battery storage systems. Knowing the manufacturer and model of each component can help you verify warranty coverage, access technical support, and find qualified service providers familiar with your equipment.

Solar Panel Brand

Solar panels are responsible for converting sunlight into electricity and are the most visible part of your solar system. Former ADT Solar installations commonly feature panels from manufacturers such as:

• Qcells

• REC

• Silfab

• Panasonic

You can typically find the panel manufacturer listed in your installation documents or on a label attached to the back of the solar modules. Since many panel manufacturers offer product warranties of 20 to 25 years, identifying the brand is an important first step when investigating performance issues or potential warranty claims.

Inverter Brand

The inverter is the heart of your solar system, converting the direct current (DC) generated by your panels into usable alternating current (AC) for your home. Common inverter brands found on ADT Solar systems include:

• Enphase

• SolarEdge

• SMA

If your system experiences reduced production, monitoring failures, or error messages, the inverter is often one of the first components that should be checked. Knowing the inverter manufacturer can help you access diagnostic tools, technical support, and warranty services directly from the company.

Battery Brand

If your solar system includes energy storage, you should also identify the battery manufacturer and model. Popular battery solutions installed alongside residential solar systems include:

• Tesla Powerwall

• Enphase IQ Battery

Battery systems often carry separate warranties and support programs from the solar installation itself. Having the battery information readily available can simplify troubleshooting and ensure you receive the appropriate support if storage-related issues arise.

Knowing who manufactured your solar panels, inverter, and battery is critical because warranty protection may still be available directly through the equipment providers, even if your original installer is no longer operating. This information can save time, streamline service requests, and help ensure your system continues to operate efficiently for years to come.

Step 3: Contact Manufacturers

Once you have identified the brands and models installed on your system, the next step is to contact the equipment manufacturers directly. Even if ADT Solar is no longer available to provide support, many manufacturers continue to honor their product warranties and offer assistance to homeowners experiencing equipment-related issues.

Manufacturers may be able to assist with the following:

• Verify Warranty Status
  Confirm whether your solar panels, inverter, battery, or other components are still covered under the manufacturer's warranty.

• Review Equipment Diagnostics
  Analyze system performance data, error codes, and monitoring information to help identify potential equipment failures.

• Recommend Certified Service Providers
  Direct you to authorized installers or service technicians in your area who are trained to work on their products.

• Assist With Replacement Claims
  Guide you through the warranty claim process and coordinate replacement equipment if a covered component has failed.

Having your equipment serial numbers readily available before contacting support can significantly speed up the process and help manufacturers provide more accurate assistance. In many cases, direct communication with the manufacturer is the fastest way for solar orphan homeowners to resolve equipment issues and access available warranty benefits.

Step 4: Find an Independent Solar Service Company

If your original installer is no longer available, partnering with an independent solar service provider is often the best way to ensure your system continues operating efficiently. Many solar companies now specialize in assisting solar orphan customers, offering maintenance, repair, and warranty support for systems installed by defunct or inactive installers.

When evaluating service providers, look for companies that have experience working with the specific equipment installed on your home. Familiarity with your panel, inverter, and battery brands can help speed up diagnostics, repairs, and warranty claims.

Finding a qualified service provider is important for long-term system maintenance, but homeowners can often monitor system performance themselves using manufacturer-supported monitoring applications. 

Can You Monitor Your ADT Solar System Yourself?

In many cases, customers can continue monitoring their solar system even after the installer's closure. The process depends on the equipment installed and whether access to the monitoring platform can be transferred or restored. Monitoring your system regularly is important because it allows you to track energy production, identify performance issues, and detect equipment failures before they significantly impact your savings.

Common monitoring options include:

• Enphase – Homeowners may be able to regain access through the Enphase monitoring platform and mobile app, depending on account ownership and system registration.

• SolarEdge – Customers can often work directly with SolarEdge to restore monitoring access and view system performance data through the company's monitoring portal.

• Tesla – Systems equipped with a Tesla Powerwall or other Tesla energy products are typically monitored through the Tesla mobile app, which provides real-time production and storage information.

Once monitoring is in place, homeowners can use the data provided by these platforms to identify issues early and implement preventive maintenance strategies. 

How to Prevent Future Solar Problems

Even if your solar system is currently operating without issues, taking a proactive approach can help prevent unexpected failures, reduce repair costs, and maximize long-term energy production. For solar orphan homeowners, regular system oversight is especially important since there is no original installer actively monitoring the system's performance.

Here are a few best practices to help keep your solar system running smoothly:

• Monitor Production Monthly
  Review your system's energy production on a regular basis. Sudden drops in output may indicate equipment failures, shading issues, or communication problems that require attention.

• Save All Documentation
  Keep digital and physical copies of important records, including:

  • Installation contracts

  • Warranty documents

  • Permits and inspection reports

  • Electrical diagrams and system specifications

• Schedule Periodic Inspections
  Professional inspections every few years can identify hidden issues such as loose wiring, damaged components, corrosion, or roof-related concerns before they become major problems.

• Verify Warranty Coverage
  Familiarize yourself with your equipment warranties, including:

  • Coverage periods

  • Labor provisions

  • Warranty exclusions

  • Transferability requirements

• Establish a Relationship With a Service Provider
  Working with a trusted solar maintenance company such as Sunny Energy RX before problems arise can make future repairs and warranty claims much easier. Having a reliable service partner in place can also reduce system downtime and help ensure ongoing support when needed.
