When investing in solar panels, one of the key factors to consider is the warranty. Most solar panels come with a warranty of around 25 years, which gives peace of mind for long-term use. However, not all warranties are created equal, and understanding what they cover can help ensure you make the right choice for your solar system.
Why Solar Panel Warranties Matter?
One of the key factors to consider when investing in solar panels is warranty. Most solar companies offer a warranty on their panels for around 25 years, which gives you peace of mind for the long term. However, not all warranties are created equal, and understanding what is covered can help you ensure you make the right choice for your solar system.
Types of Solar Panel Warranties
Product (Equipment) Warranty
This warranty covers defects in materials or workmanship of the solar panels. If a panel malfunctions due to manufacturing issues, the manufacturer will repair or replace it. Standard product warranties typically last between 10 to 12 years, with some premium panels offering up to 25 years of coverage.
Performance (Power Output) Warranty
Over time, solar panels experience a natural decline in their ability to generate electricity, known as degradation. Performance warranties guarantee that this degradation will not exceed a specified rate over a certain period, ensuring the panels produce a minimum percentage of their original output. For example, a common performance warranty guarantee at least 90% of the original output after 10 years and 80% after 25 years.
Labor (Workmanship) Warranty
This warranty covers issues arising from the installation process, such as improper mounting or electrical problems. Labor warranties are typically provided by the installation company and can range from 1 to 10 years, depending on the installer.

How to Compare Solar Panel Warranties?
When comparing solar panel warranties from different manufacturers, it’s essential to focus on several key factors. Here’s how you can effectively compare them:
-
Warranty Length: The most obvious factor to compare is the duration of the warranty. Some manufacturers offer warranties of 10 to 15 years, while top brands provide up to 25 years. The longer the warranty, the better the protection.
-
Product vs. Performance Warranty: Check if the manufacturer offers both a product warranty and a performance guarantee. The product warranty covers physical defects, while the performance guarantee ensures your panels will still produce a certain percentage of their original output over time. Ideally, you want a company that offers strong warranties for both.
-
Degradation Rate: Pay attention to the degradation rate promised in the performance warranty. A lower degradation rate means that your panels will retain more of their efficiency over time. For example, some companies guarantee 90% efficiency after 25 years, while others may offer only 80%.
-
Transferability: If you plan to sell your home, it's worth checking whether the warranty is transferable to the new owner. A transferable warranty can add value to your property and ensure continued protection for the solar system.
-
Exclusions and Fine Print: Look carefully at what is not covered by the warranty. Certain exclusions, like damage from extreme weather or improper maintenance, may affect how much coverage you actually get.
-
Customer Service: Lastly, check reviews of the manufacturer’s customer service. A good warranty is only as helpful as the company standing behind it. You want to ensure that the company will be responsive and helpful if you ever need to make a claim.
What Can Void a Solar Panel Warranty?
Even with a solid warranty in place, certain actions or conditions can void it, leaving you without coverage.
Improper Installation
Installing solar panels incorrectly or not following the manufacturer's guidelines can void the warranty. It's essential to use certified professionals for installation to ensure compliance with all requirements.
Unauthorized Repairs or Modifications
Attempting DIY repairs or hiring unauthorized personnel to modify your solar system can lead to warranty nullification. Always consult the manufacturer or authorized service providers for any repairs or changes.
Neglecting Maintenance
Failing to perform regular maintenance, such as cleaning and inspections, can cause issues that may void the warranty. Adhere to the maintenance schedule recommended by the manufacturer to keep the warranty intact.
Environmental Damage
Damage from natural disasters like hurricanes, floods, or lightning strikes is typically not covered under standard warranties. Consider additional insurance to protect against such events.
Using Non-Approved Accessories
Integrating components or accessories not approved by the manufacturer can lead to system issues and void the warranty. Ensure all parts used are compatible and manufacturer-approved.
Improper System Usage
Using the solar panel system beyond its intended capacity or for unintended applications can result in warranty voidance. Operate the system within the specified parameters to maintain warranty coverage.
Non-Compliance with Local Codes
Installing the system in violation of local building codes or regulations can void the warranty. Ensure compliance with all relevant codes during installation.
Roof-Related Issues
In some cases, installing solar panels can void your roof warranty if the roofing system is damaged during the installation process. It's important to coordinate with both your roofing and solar installation companies to ensure that warranties remain valid.
To preserve your solar panel warranty, always follow the manufacturer's guidelines, use authorized service providers, and maintain proper documentation of all maintenance and repairs. This diligence will help ensure your warranty remains valid throughout its term.
