Investing in solar panels is not only a smart decision for a sustainable future but also a significant financial commitment. As you explore your solar options, one aspect you should pay close attention to is the warranty that comes with your solar panels. Solar panel warranties can vary, and understanding what’s covered and what’s not is crucial. In this blog, we’ll demystify solar panel warranties to help you make an informed decision.

The Two Main Types of Solar Panel Warranties

Solar panel warranties generally come in two main categories:

Performance Warranty: This warranty guarantees that your solar panels will produce a certain amount of electricity over a specified period. It typically lasts 25 years and ensures that your panels will maintain a minimum level of efficiency throughout that time.

Product Warranty: Also known as the manufacturer’s warranty, this covers any defects in materials or workmanship of the solar panels. The duration of a product warranty can vary from 10 to 25 years, depending on the manufacturer.

What’s Covered by Solar Panel Warranties?

Performance Warranty:

Power Output: The performance warranty ensures that your solar panels will produce a minimum percentage of their rated power output over time, typically 80% or more after 25 years.
Efficiency: It covers any drop in efficiency below the guaranteed level. If your panels fall short of the promised performance, the manufacturer may replace or compensate you for the lost energy production.
Product Warranty:

Material Defects: Product warranties cover any issues related to the quality of materials used in the solar panels. This includes issues like delamination (layers separating), corrosion, and other material defects.
Workmanship: If there are defects in the manufacturing or assembly of the panels, such as loose connections or faulty soldering, the product warranty should cover these issues.
What’s Not Covered by Solar Panel Warranties?

External Factors: Solar panel warranties typically do not cover damage caused by external factors such as natural disasters (e.g., hailstorms), vandalism, or improper installation and maintenance.

Degradation Within Specified Limits: While performance warranties guarantee a certain level of efficiency over time, they do not cover degradation that falls within the specified limits. For example, if your panels degrade from 100% to 80% efficiency within 25 years, they are still within the warranty’s coverage.

Failure to Meet Maintenance Requirements: If you neglect proper maintenance of your solar panels, any damage or efficiency loss resulting from your negligence may not be covered by the warranty.

Tips for Maximizing Your Warranty Benefits

Choose a reputable solar panel manufacturer with a solid track record of honoring warranties.
Follow recommended maintenance procedures to ensure your panels operate at their best.
Keep thorough records of your solar panel installation and any maintenance and repairs.
In conclusion, understanding the nuances of solar panel warranties is essential to protect your investment. While warranties provide peace of mind, it’s equally important to choose high-quality panels and have them installed by a qualified professional. By doing so and adhering to maintenance guidelines, you can maximize the benefits of your solar panel warranty and enjoy the long-term financial and environmental advantages of solar energy.
