You've made a smart investment by choosing solar for your home. Your solar system can save money, reduce your carbon footprint, and provide reliable power for decades. But like any major investment, your panels need ongoing attention to maintain peak performance. That's where understanding your solar panel warranty becomes essential.
Solar panels are built to last, but they face the elements constantly. From harsh weather to normal wear and tear, repairs may become necessary. Having comprehensive solar panel warranty coverage ensures you're protected if issues arise. Without proper warranty protection, solar panel repair costs can quickly add up, diminishing your long-term savings.
A good solar panel warranty provides:
Protection against manufacturing defects
Guaranteed solar power production levels over time
Coverage for solar repair or replacement costs
Peace of mind for your long-term investment
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 protects your investment. It covers defects in materials, performance, and often labor, providing peace of mind for years to come.
Understanding what's covered by your solar panel warranty is crucial. Manufacturers typically exclude coverage for improper installation, neglected maintenance, and damage from natural disasters or vandalism. Knowing these details helps you avoid denied solar panel warranty claims and unexpected repair costs.
5 Tips to Avoid a Void Solar Panel Warranty Coverage
Protecting your solar panel warranty ensures long-term performance and financial benefits. Follow these key steps to keep your coverage intact so you can make a solar panel warranty claim if needed.
Register Your Panel Warranty Immediately: Some manufacturers require product registration to activate coverage. Completing this step ensures your warranty is valid, protecting against defects or performance issues. Many solar installers will handle this on your behalf.
Follow Manufacturer Maintenance Guidelines: Routine cleaning and inspections help maintain efficiency and longevity. Using approved cleaning methods and recommended maintenance practices ensures solar panel warranty claims are approved.
Use Approved Installers and Components: Many solar panel warranties specify certified installers and compatible equipment. Choosing approved professionals and components supports long-term system reliability and keeps your warranty in effect.
Keep All Documentation and Proof of Purchase: Maintaining records of your purchase, installation, and maintenance history simplifies the warranty claims process. These documents confirm eligibility for repairs or replacements.
Understand Performance Degradation Terms: Performance warranties guarantee a specific power output over time (e.g., 80–90% after 25–30 years). If output declines beyond the guarantee, a warranty claim can help restore efficiency.
Types of Solar Panel Warranties
Different types of solar panel warranty coverage offer various protections. Here's a breakdown of the most common warranty types:
Solar Panel Product Warranty
This warranty covers defects in materials or manufacturing. If a panel is faulty due to component issues, this warranty ensures the manufacturer will repair or replace it.
Product warranties typically last 10-25 years, depending on the manufacturer and panel quality. Premium panels often come with longer solar panel warranty periods, providing extended protection.
Solar Panel Power Performance Guarantee
This guarantee ensures your panels maintain specific efficiency levels over time. Solar panels naturally degrade, reducing their electricity conversion ability as they age. This warranty guarantees your panels will retain a minimum percentage of their original efficiency.
Most manufacturers guarantee their panels will produce at least 90% of original output after 10 years and 80% after 25 years. This protection ensures continued energy savings even as your system ages.
Solar Panel Labor Warranty
Labor warranties cover the costs of replacing faulty panels. This solar panel warranty coverage is often separate from product and performance warranties. Labor represents a significant portion of solar panel repair costs, making this warranty essential for protection against unexpected expenses.
Labor warranties typically range from 1-10 years, depending on the installer and manufacturer. If you need a panel replaced, this warranty covers removal, replacement, and reinstallation costs. Unfortunately, many solar companies have closed recently, leaving homeowners with orphaned systems and potentially expired labor warranties.
What's Not Covered by a Solar Panel Warranty?
While these warranties provide substantial protection, certain exclusions exist. Issues like improper installation, lack of maintenance, or damage from hurricanes, floods, or hailstorms typically aren't covered. Many warranties also exclude solar panel warranty void situations caused by environmental factors, vandalism, or unauthorized repairs.
If your panel suffers weather damage, you'll likely need homeowner's insurance rather than relying on your solar panel warranty. To avoid warranty issues, ensure certified professionals handle installation and perform recommended maintenance. Avoid DIY solar panel repairs, as they can void your warranty completely. Likewise, avoid damaging solar panels when cleaning or removing snow from solar panels.
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
Check your original installation paperwork first. Most installers provide documentation including warranty details for panels, inverters, and other components.
Can't find your paperwork? Contact your installer directly. They should have records of your system specifications and warranties. They can help determine if your issue qualifies for a solar panel warranty claim or requires out-of-pocket repair.
2. Research Your Solar Panel Brand
If your installer is unavailable or out of business, find solar panel warranty information by researching your panel manufacturer. Most solar companies list warranty details on their websites, including downloadable documents.
When researching your solar panel warranty, check:
Solar panel product warranty duration (typically 10–25 years)
Power performance guarantee percentages
Labor warranty terms and coverage
Conditions that could void your solar panel warranty
3. Review Your Purchase Documents
Check your contract or invoice if you financed or purchased your system outright. These documents often contain warranty coverage details. If you leased your system, your leasing company may handle solar panel repairs under your agreement terms.
How to File a Solar Panel Warranty Claim
If your panels aren't performing properly, you may need to file a solar panel warranty claim. The process typically follows these steps:
Contact Your Installer – Your original installer is usually the first point of contact. If they're no longer operating or you're unsatisfied with their work, GreenLancer can connect you with qualified repair technicians nationwide.
System Inspection – An inspection may be required to verify the issue falls under your solar panel warranty coverage. Some manufacturers require specific documentation or testing before approving claims.
Solar Panel Warranty Claim Approval – If the problem qualifies, the manufacturer or installer will approve repair, replacement, or rarely, a refund. The approval process depends on your warranty terms and the issue's nature.
Repair or Replacement Process – If your claim is approved, the faulty panel will be repaired or replaced. Some warranties cover all solar panel repair costs, including labor, while others may require you to pay for installation. If your solar warranty is void due to improper installation or unauthorized modifications, you'll need alternative repair options.
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 warranties require certified professional installation. DIY installations or hiring unqualified contractors can void your warranty if errors cause damage.
Lack of Maintenance – Neglecting system maintenance, like allowing debris accumulation or ignoring damaged wiring, can be grounds for denying a solar panel warranty claim.
Unauthorized Repairs or Modifications – Unapproved system changes, like using non-manufacturer components or tampering with wiring, can void your warranty. Always check terms before making adjustments.
Environmental Damage – Though solar panels withstand harsh conditions, most warranties don't cover hurricane, hailstorm, fire, flood, or vandalism damage. Consider additional homeowners insurance coverage for complete protection.
