| A solar system warranty can protect homeowners from equipment defects, installation-related issues, and certain component failures, but coverage varies by provider. Learn what warranties typically cover, what can void them, how annual inspections help prevent problems, and why owners of orphaned solar systems still have options when service or warranty support is needed. |
While today’s solar panels and equipment are built to last, no system is completely immune to manufacturing defects, equipment failures, or installation-related issues. That’s where solar system warranties come in, providing an added layer of protection and peace of mind.
But not all solar warranties are created equal.
Coverage can vary depending on the manufacturer, installer, and components involved, with some warranties covering equipment and others extending to workmanship or labor.
For solar power system owners, knowing the details of your warranty can be just as important as understanding how your system works. It can make the difference between a straightforward repair process and unexpected out-of-pocket expenses.
8 Things the Best Solar Warranties Cover
The exact coverage provided by a solar system warranty depends on the manufacturers and installers involved. However, most warranties are designed to address equipment defects, installation-related issues, and other problems that may impact the safety, performance, or reliability of your system.
Common items covered by a solar system warranty include:
- Solar panels
- Inverters
- Optimizers and microinverters
- Workmanship and installation defects
- Roof penetrations and leaks
- Mounting and racking systems
- Roof penetration and leaks
- Battery storage systems
1. Solar Panels
Most manufacturers provide warranties that protect against defects in materials and workmanship. Many also include a performance warranty that guarantees the panels will continue producing electricity at a specified level over time.
2. Inverters
Inverters are among the hardest-working components in a solar energy system, making warranty coverage particularly important. Depending on the manufacturer and model, inverter warranties often range from 10 to 25 years.
3. Optimizers & Microinverters
Many modern solar systems use optimizers or microinverters to maximize energy production and improve system performance. These components often carry their own manufacturer warranties and may be covered for 20 years or more, depending on the product.
4. Workmanship & Installation Defects
A workmanship warranty covers issues related to how the system was installed rather than the equipment itself. This can include problems resulting from improper wiring, faulty connections, or installation errors that affect system performance.
5. Roof Penetrations & Leaks
When solar panels are installed on a roof, mounting hardware requires carefully sealed penetrations. Many installation warranties cover leaks or water intrusion that can be traced back to the solar installation process.
6. Mounting & Racking Systems
The racking system that secures solar panels to your roof or ground mount is also often covered under warranty. Coverage typically applies to manufacturing defects or premature failures that impact the structural integrity of the system.
7. Monitoring Equipment & Communications Devices
Monitoring systems help homeowners track energy production and identify performance issues. Depending on the manufacturer and equipment involved, warranty coverage may extend to monitoring hardware, communication gateways, and related devices that support system monitoring.
8. Battery Storage Systems
If your solar energy system includes battery storage, the batteries and associated equipment typically have separate warranty coverage. These warranties often address defects, performance degradation, and overall battery capacity retention over a specified period of time.
6 Things Solar System Warranties Don’t Always Cover
Solar system warranties do have their limits with coverage.
In many cases, problems caused by external factors, improper maintenance, or events outside the manufacturer’s control are not covered.
- Storm and weather damage
- Physical damage caused by accidents
- Normal wear and tear
- Improper maintenance or neglect
- Damage caused by pests or animals
- Unauthorized modifications or repairs
1. Storm & Weather Damage
Most warranties do not cover damage caused by severe weather events such as hail, high winds, lightning strikes, or falling trees. These situations are often handled through a homeowner’s insurance policy rather than a warranty claim.
2. Physical Damage Caused by Accidents
Accidental damage is generally excluded from warranty coverage. This can include damage caused during roof work, home renovations, or other activities that impact the solar energy system.
3. Normal Wear & Tear
Solar equipment is designed to withstand years of outdoor exposure, but gradual aging is expected. Warranties typically do not cover cosmetic changes, minor deterioration, or other forms of normal wear and tear.
4. Improper Maintenance or Neglect
Failure to properly maintain your system may affect warranty eligibility. Ignoring known issues or allowing minor problems to worsen can sometimes lead to denied claims.
5. Damage Caused by Pests or Animals
Birds, squirrels, rodents, and other animals can occasionally damage wiring or system components. Because this damage is caused by outside factors, it is often excluded from standard warranty coverage.
6. Unauthorized Modifications or Repairs
Making modifications to your solar energy system or allowing unqualified individuals to perform repairs can create safety concerns and may void portions of your warranty. If you suspect a problem, it’s always best to work with a qualified solar professional.
What Voids a Solar Panel Warranty?
Having a warranty is valuable, but maintaining that coverage is just as important. Manufacturers and installers typically require solar systems to be installed, serviced, and maintained according to specific guidelines. Failing to follow those requirements can sometimes void part or all of a warranty.
One of the most common causes of warranty issues is allowing an unqualified individual to perform work on the system. Solar energy systems involve specialized electrical equipment, wiring, and mounting components that require proper training and experience. If unauthorized repairs, modifications, or alterations are made, manufacturers may deny future warranty claims.
Improper installation can also create warranty complications. If a system was not installed according to manufacturer specifications, certain components may not qualify for coverage.
While every warranty is different, most providers expect system owners to take reasonable steps to protect and maintain their equipment.
The best way to avoid unexpected warranty issues is to carefully review your warranty documents and work with qualified solar professionals whenever service or repairs are needed. Taking the right approach today can help ensure your coverage is there when you need it most.
Staying Ahead of Having to Use Your Warranty
Though there’s no way to completely eliminate the possibility of equipment failures or unexpected issues. Even the best solar panel warranty can’t prevent every problem. However, there are steps homeowners can take to identify concerns early and reduce the likelihood of costly repairs.
The #1 thing you can do is schedule a professional solar system inspection once a year. During an inspection, technicians can evaluate your panels, inverter, wiring, mounting system, and overall performance to identify signs of wear, damage, or declining production before they become larger problems.
Annual inspections can also help uncover issues that may not be obvious to the average homeowner. Loose connections, damaged wiring, pest activity, and equipment faults can sometimes go unnoticed until they begin affecting energy production or system reliability.
In addition to annual inspections, it’s important to monitor your system’s performance and address any unusual production changes promptly. Catching small issues early can help keep your system operating efficiently and may simplify the warranty claim process if a covered problem is discovered.
While no solar energy system is completely maintenance-free, a proactive approach can go a long way toward protecting your investment and helping your system deliver reliable performance for decades.
My Solar Company Went Out of Business. Where Do I Turn to for Help Filing a Warranty Claim?
Discovering that your solar installer is no longer in business can be frustrating, especially if your system needs service or you believe a warranty claim may be necessary. Fortunately, having an orphaned solar system does not automatically mean you’ve lost all warranty protection.
In many cases, manufacturer warranties remain in effect even if the original installer is no longer operating. However, navigating the warranty process can be challenging without an experienced solar professional to diagnose the issue, communicate with manufacturers, and perform any necessary repairs or replacements.
Solar by CIR regularly helps homeowners with solar system maintenance issues, determine whether warranty coverage may apply, and work through the claims process when appropriate.
Beyond warranty assistance, orphaned solar system owners often need ongoing maintenance, inspections, repairs, monitoring support, or replacement equipment.
If your original solar installer is no longer available, you’re not out of options. With the right support, many warranty claims can still be pursued, and many system issues can still be resolved without replacing the entire system.
Solar System Warranties for Peace of Mind
A solar energy system is built to provide decades of value, and understanding your warranty is an important part of protecting that investment.
Whether you’re reviewing coverage, staying proactive with annual inspections, or looking for help with an orphaned system, having the right support can make all the difference when issues arise.
