A Comprehensive Guide to Solar Panel Warranties

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 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.

Why is a solar panel warranty so important?

One of the key factors to consider when investing in solar panels is warranty. Most solar companies offer around 25 years of warranty on solar panels, giving you long-term peace of mind. 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.

Solar Panel Warranty Types

When looking at solar panel warranties, you’ll find that there are generally four main types: product warranty, performance warranty, power warranty, and installation warranty.

Product Warranty

A product warranty covers defects in materials and workmanship in solar panels. This warranty ensures that if the solar panel itself fails due to manufacturing issues, the manufacturer will repair or replace it. Most product warranties last between 10 and 25 years, depending on the brand. High-quality solar panels often have longer product warranties, which shows that the manufacturer is confident in its product.

Performance Guarantee

Solar panels naturally degrade over time , meaning they produce less energy as they age. A performance guarantee ensures that your panels will maintain a certain level of efficiency for a specified period. Typically, manufacturers guarantee that their panels will still produce 90-85% of their original capacity after 20 years. If your panel’s performance falls below this level, you may be eligible for a replacement or repair under this warranty.

Power Supply Warranty

A power warranty focuses on the energy output of your solar panels. It is similar to a performance warranty, but usually emphasizes continued energy production over the life of the panel. While this warranty sounds similar, it specifically covers any significant drop in the amount of power generated by the panel beyond normal degradation. If your panels fail to produce the energy they should, a power warranty may cover the cost of repairing or replacing them.

Installation Warranty

This warranty is usually provided by the installer rather than the manufacturer. It covers any issues related to the actual installation of the panels, such as mounting problems, wiring problems, or leaks caused during the installation process. Most installation warranties last about 5 to 10 years.

The Best Solar Panel Warranties on the Market

When buying solar panels, it’s worth looking at brands that offer the best warranties. These warranties can be a good indication of product quality and long-term reliability. Here are some of the top brands known for offering comprehensive solar panel warranties:

1. SunPower
   is known for offering some of the best warranties in the industry. Their product warranty is 25 years, covering defects in materials and workmanship. In addition, they offer a performance guarantee that ensures their solar panels will still produce 25% of their original power output after 92 years. This is one of the highest performance guarantees available.
2. LG Solar
   LG solar panels come with a 25-year product warranty and performance guarantee, guaranteeing that their power output will be restored to 90.8% of the original output after 25 years. LG is also known for the durability and efficiency of its solar panels, making them a reliable choice for homeowners.

What Doesn’t a Solar Panel Warranty Cover?

While solar panel warranties are comprehensive, there are several things they typically don’t cover. Here are some common things solar warranties typically don’t cover:

• Natural disasters : Events such as hurricanes, tornadoes, hail, and lightning strikes are not usually covered by insurance. For these events, you need homeowners insurance.
• Damage caused by pests : Animals such as birds, squirrels, or rodents that cause damage to your panels are usually not covered by the warranty.
• User Error : If you or someone without proper training attempts to modify or repair the system and damage occurs, the warranty will be void.
• Shading issues : If your solar panels produce less energy because they were installed without taking into account shading from trees or nearby buildings, this is generally not covered by the warranty.
• Wear and tear : Normal wear and tear or degradation of performance beyond the natural performance limits of the panel is not usually covered, as the warranty only covers severe underperformance.
• Improper Maintenance : Failure to maintain your solar panels according to the manufacturer’s recommended maintenance can also void part of your warranty. It is vital to strictly follow maintenance guidelines.

How to Compare Solar Panel Warranties?

When comparing solar panel warranties from different manufacturers, it’s important to focus on several key factors. Here’s how to compare them effectively:

1. Length of warranty : The most obvious comparison factor is the length of the warranty. Some manufacturers offer 10 to 15-year warranties, while top brands offer up to 25 years. The longer the warranty, the better the protection.
2. Product vs. Performance Warranty : Check to see if the manufacturer offers both a product warranty and a performance warranty. A product warranty covers physical defects, while a performance warranty ensures that your solar panels will continue to produce a certain percentage of their original output for a certain period of time. Ideally, you want a company that offers strong warranties for both.
3. Degradation rate : Pay attention to the degradation rate promised in the performance guarantee. A lower degradation rate means your solar panels will remain more efficient over time. For example, some companies guarantee 25% efficiency after 90 years, while others may only guarantee 80%.
4. 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 increase the value of your property and ensure your solar system continues to be protected.
5. Exclusions and the fine print : Take a close look at what your warranty doesn’t cover. Certain exclusions, such as damage from extreme weather or improper maintenance, may affect the actual coverage you get.
6. Customer Service : Finally, check reviews of the manufacturer’s customer service. A good warranty is only as good as the company that offers it. You want to make sure that the company is responsive and helpful if you need to file a claim.

What conditions will void your solar panel warranty?

Even with a solid warranty, certain actions or conditions may void the warranty and leave you without coverage.

1. Unauthorized repairs or modifications : If you or an unqualified technician attempts to repair or modify the panel, the warranty will be void. Always use an authorized technician for repairs or upgrades.
2. Improper installation: If a certified professional doesn’t install the panels, the warranty may not cover any problems that arise. That’s why it’s important to choose a reputable solar installer.
3. Neglect or poor maintenance : Failure to properly clean or maintain your solar panels within the manufacturer’s guidelines can void your warranty. For example, allowing debris to build up or neglecting routine inspections could be considered neglect.
4. Environmental conditions : If your panel is exposed to an environment it was not designed to withstand, such as extreme temperatures or harsh chemicals, this may void your warranty.
5. Removing or relocating panels : If you decide to move or remove panels without following the correct procedures or using a qualified installer, this may void your warranty.

How do I make a solar panel warranty claim?

If you experience issues with your solar panels and need to make a warranty claim, it’s important to follow the correct steps to ensure a smooth process.

1. Check your warranty : Before filing a claim, check your warranty documentation to confirm if the issue you are experiencing is covered. Make sure you understand which type of warranty (product, performance, or installation) applies to the issue.
2. Contact the manufacturer or installer : Depending on the terms of the warranty, you will need to contact the manufacturer or installer. Many manufacturers prefer that you contact the original installer first, especially for installation warranties.
3. Gather documentation : Be prepared to provide documentation such as the purchase receipt, installation date, and any maintenance or inspection records. Photos of the damage or problem can also help speed up the process.
4. Schedule an inspection : In most cases, the manufacturer or installer will send a technician to inspect the solar panels and verify the problem. This inspection helps determine if the problem is covered under warranty.
5. Replacement or Repair : If the claim is approved, the manufacturer will repair the panel or provide a replacement. Some warranties may also cover labor costs, while others may require you to pay for labor.
6. Follow up after the course : Stay in touch with the manufacturer or installer to make sure the process is going smoothly. If there are delays or complications, always ask for updates.
