You’ve made a smart investment by choosing solar for your home. A well-designed system can lower your energy bills, reduce your carbon footprint, and deliver clean power for decades. But like any major investment, it’s important to understand your solar panel warranty so you’re prepared if anything goes wrong.
Even though solar panels are built to endure, they constantly face harsh weather and environmental wear. Over time, repairs may be needed. That’s when having solid solar panel warranty coverage makes all the difference. Without the right protection, out-of-pocket solar panel repair costs can undercut your long-term savings.
A good solar panel warranty provides:
Coverage for manufacturer defects and premature equipment failures
A solar panel guarantee for long-term energy production
Support for repair or replacement labor in some cases
Peace of mind knowing your investment is protected
GreenLancer has been a trusted solar energy partner for over a decade. We understand how important it is to properly use your solar panel warranty. Whether you're dealing with panel repairs or navigating solar panel warranty claims, knowing what's covered—and what might void your warranty—helps prevent unexpected expenses.
What Is a Solar Panel Warranty?
A solar panel warranty is a manufacturer's guarantee that your panels will perform as expected for years. These warranties typically cover material defects, performance issues, and sometimes labor, offering essential protection for your solar investment.
Understanding your solar panel warranty information helps you avoid costly surprises. Most solar panel warranties exclude coverage for improper installation, poor maintenance, or damage from extreme weather or vandalism. Knowing these exclusions upfront can prevent denied solar panel warranty claims down the line.
5 Tips to Avoid Voiding Solar Panel Warranty Coverage
Keeping your solar panel warranty coverage intact helps preserve system performance and long-term savings. Follow these best practices to maintain eligibility and streamline any solar panel warranty claim:
Register Your Solar Panel Warranty Early
Some manufacturers require product registration to activate coverage. Don’t delay—make sure your solar panel guarantee is in place. Many installers complete this step for you, but it’s worth confirming.
Stick to Manufacturer Maintenance Guidelines
Regular maintenance—like safe cleaning and periodic inspections—keeps your system running smoothly. Follow approved methods to protect your solar panel warranty from being voided due to neglect.
Use Certified Installers and Compatible Equipment
Most solar panel warranties require installation by certified professionals and the use of approved components. Choosing the right team ensures system reliability and keeps your solar panel warranty information valid.
Save All Documentation
Keep records of your purchase, installation, maintenance, and repairs. These documents are essential if you ever need to file a solar panel warranty claim.
Know the Performance Guarantee Terms
Most manufacturers offer a performance solar panel guarantee, ensuring a certain output over 25 to 30 years. If your panels underperform beyond this threshold, you may be eligible for repair or replacement under your solar panel warranty.
Types of Solar Panel Warranties
Not all solar panel warranties are created equal. Understanding the different types of solar panel warranty coverage can help you protect your investment and avoid costly surprises. Here’s a breakdown of the most common types of solar panel warranty information available today.
Solar Panel Product Warranty
A solar panel product warranty covers defects in materials or workmanship. If a panel fails due to a manufacturing flaw or faulty components, the manufacturer is responsible for repair or replacement.
Most product warranties last between 10 and 25 years.
Higher-end panels often come with longer solar panel warranty periods.
This is the baseline protection every system should have.
Solar Panel Power Performance Guarantee
The performance guarantee, sometimes called a solar panel output warranty, ensures your panels produce a minimum percentage of their rated power over time. All panels lose efficiency gradually, but this solar panel guarantee protects you from excessive degradation.
A typical solar panel warranty guarantees at least 90% output at year 10 and 80% by year 25.
This ensures consistent long-term energy savings.
If performance drops below guaranteed levels, you're eligible for remediation or replacement.
Solar Panel Labor Warranty
This lesser-known but critical solar panel warranty coverage protects against labor costs associated with panel removal, replacement, or reinstallation. It's especially important now, as many original installers have exited the market, leaving homeowners with orphaned solar systems and expired labor coverage.
Solar panel labor warranties typically last between 1 and 10 years.
Some are offered by the installer, while others are backed by manufacturers.
Without this, even covered equipment failures could result in out-of-pocket labor costs.
What's Not Covered by a Solar Panel Warranty?
Even the best solar panel warranties have limitations. Understanding what’s excluded helps you avoid costly surprises and protects your investment.
Most solar panel warranty information clearly states that damage caused by improper installation, poor maintenance, or extreme weather events, such as hurricanes, floods, and hailstorms, is not covered. Issues such as vandalism, environmental stress, or repairs made by unapproved technicians may also void your solar panel guarantee.
If your panels are damaged by severe weather, you’ll likely need to file a claim through your homeowner’s insurance rather than relying on your solar panel warranty. To avoid warranty disputes, always use certified installers and follow the manufacturer’s maintenance recommendations. Avoid do-it-yourself repairs or using abrasive tools when cleaning or removing snow, as these can void your solar panel warranty coverage entirely.
Where to Find Your Solar Panel Warranty Information
If you're experiencing system issues or want to review coverage, knowing where to find your solar panel warranty details is important. Your warranty outlines coverage, duration, and what could create a solar warranty void situation. Here's where to look:
1. Solar System Ownership Documents
Start with the paperwork you received when your system was installed. Most installers include documents outlining the solar panel warranties, inverter protection, and other equipment guarantees.
If you can't locate these records, contact your original installer. They should have documentation to confirm whether your issue qualifies for a solar panel warranty claim or if it might require repair outside of warranty.
2. Check Your Solar Panel Manufacturer
If your installer is no longer in business, you can find solar panel warranty information directly through the panel manufacturer. Most major brands publish warranty documents on their websites, detailing their solar panel product warranties, performance guarantees, and any conditions that could void your coverage.
When reviewing your manufacturer’s information, look for:
The length of the solar panel product warranty (often 10–25 years)
Details of the solar panel guarantee on power output
Any solar panel labor warranty provisions
Specific exclusions or voiding conditions
3. Review Your Purchase Documents or Lease Agreements
If you financed or bought your solar system outright, your contract or invoice may include a summary of the solar panel warranty terms. For leased systems, warranty support is often handled by the leasing company, which typically manages solar panel repairs under the lease agreement.
Understanding where to find accurate solar panel warranty information helps you avoid guesswork and unnecessary repair costs when system issues arise.
How to File a Solar Panel Warranty Claim
If your system isn’t performing as expected, you may need to file a solar panel warranty claim. Understanding how the process works can help you avoid delays and ensure your coverage is honored under your solar panel warranties.
Contact Your Installer – Begin by contacting the original installer listed in your solar panel warranty information. They can confirm what’s covered and guide you through the claim process. If your installer has gone out of business or isn't responding, GreenLancer can connect you with experienced solar repair technicians.
Schedule a system Inspection – An inspection is often required to confirm the issue qualifies for warranty coverage. Some manufacturers request photos, diagnostic reports, or third-party verification before approving a solar panel warranty claim.
Wait for Solar Panel Warranty Claim Approval – Once your issue is reviewed, the manufacturer or installer will decide if repair, replacement, or reimbursement is appropriate. Approval depends on the solar panel warranty terms and the type of problem.
Complete the Repair or Replacement – If the claim is approved, the faulty panel will be repaired or replaced. Some solar panel warranties also cover labor costs, while others only apply to equipment. If your solar panel warranty is void due to installation errors or unauthorized changes, you’ll need to arrange out-of-pocket repairs.
What Can Void a Solar Panel Warranty?
While warranties protect against defects and performance issues, certain actions can void your solar panel warranty, leaving you responsible for repairs. Common warranty-voiding factors include:
Improper Installation – Many solar panel warranties require certified professional installation. DIY installations or hiring unqualified contractors can void your warranty if errors cause damage.
Lack of Maintenance – Skipping routine care, like clearing debris, inspecting wiring, or checking connections, can lead to denied solar panel warranty claims. Follow the manufacturer’s maintenance guidelines to preserve your coverage.
Unauthorized Repairs or Modifications – Making changes to your system without approval, such as using incompatible parts or altering wiring, can void your solar panel warranty. Always check the warranty terms before upgrading or repairing any part of the system.
Environmental Damage – Most solar panel warranties don’t cover damage caused by hurricanes, hail, fire, floods, or vandalism. For full protection, review your homeowner’s insurance policy to see if it covers weather-related or accidental damage.
