If there’s one trend that’s surged in popularity recently, it’s solar energy. As climate change and sustainability awareness increases, more and more homeowners are installing solar panels. Not only do solar panels help lower your carbon footprint, but they also increase your home’s value and reduce long-term energy costs.

However, before you can enjoy the benefits of solar panels, you have to decide which ones to install. There are many factors to consider, from the types of solar panels to the overall costs. While reviewing these criteria, it’s important not to overlook the solar panel warranty. For many homeowners, the warranty information can be the deciding factor in your investment.

Understanding Solar Panel Warranties

Solar panel warranties are crucial as they are guarantees from the manufacturer, ensuring that their products will adhere to certain quality standards over a designated period. Let’s delve into the three primary types of solar panel warranties:

  • Performance warranties: These warranties guarantee that solar panels will produce a certain percentage of their original power output over time. If the panels don’t meet these performance levels, the manufacturer will cover the cost of replacement panels. 
  • Product warranties: Product warranties offer coverage if you receive a damaged or defective product. If the panels break down due to subpar materials or workmanship, the manufacturer will repair or replace them. Generally, product warranties last between 10 and 15 years. 
  • Installation warranty: Also known as a workmanship warranty, this offers coverage in case problems occur due to an improper installation. It typically lasts anywhere from one to 10 years. 

Additionally, it’s important to note that many solar panel warranties are transferable. This feature allows you to pass the warranty to a new homeowner if you decide to sell your house, though some manufacturers may impose transfer fees.

At Photon Brothers, we pride ourselves on offering an exceptional 25-year production warranty, ensuring that the production and efficiency of your system will be no less than 90% of its original output. Moreover, we provide a comprehensive 25-year warranty on all labor and parts, surpassing many competitors’ offerings.

Types of Coverage: What Is Covered?

Not all issues are covered by warranties. While terms vary, many warranties offer coverage for the following:

  • Product defects: Most solar panel warranties cover defects in materials and workmanship, such as manufacturing problems or faulty components.
  • Performance quality: As mentioned earlier, warranties ensure that your solar panel will maintain a certain power output within a designated time frame. 
  • Environmental factors: Certain warranties cover physical damage caused by animals or environmental factors, such as hail, wind, or snow. 
  • Roof damage: Solar panel warranties may come with a roof warranty to protect against roof damage caused by panels or installation. Traditionally, this warranty lasts around 10 years. 
  • Human error: Many warranties specifically cover the installation of solar panels.

When it comes to coverage, our team goes above and beyond. In addition to our above-average production guarantee, we offer a 25-year workmanship and roof guarantee. Panels are covered under our 25-year production guarantee, and batteries are covered under warranty for 10 years (you can purchase an additional battery warranty for an extended warranty period if you’d like). We also provide critter protection, safeguarding your panels against unexpected damage.

Common Exclusions: What Isn’t Covered?

Even the most expansive solar panel warranties don’t cover everything. Here are a few common exclusions: 

  • Natural disasters: While some warranties cover damage from minor weather events, many exclude coverage for natural disasters such as earthquakes, floods, or lightning strikes. Depending on location, you may opt to purchase additional coverage for these risks.
  • Cosmetic wear and tear: Warranties typically don’t cover natural wear and tear, such as minor cosmetic issues. Rather, they focus on performance output. 
  • Unauthorized modifications: If the solar panels are modified without permission from the manufacturer or the original installer, the warranty may be voided. This includes attempts by third-party service providers to alter the panels. 
  • Consequential damages: Many warranties don’t cover consequential damages, such as financial loss or property damage caused by solar panel failure. You may want to seek additional insurance coverage for these risks.

If you install your panels through Photon Brothers but need to detach and re-install for any reason (such as a roof replacement), know that we offer in-house detach and reset services. When you go through us, you’ll have peace of mind that your warranties will remain valid.

Length of Warranty

The length of your solar panel warranty definitely affects your investment. Some warranties may have a tiered structure, in which the coverage percentage decreases over time. At Photon Brothers, our performance guarantee lasts a full 25 years – whether you’ve owned your solar panels for five years or two decades, you’ll enjoy the same standard of quality. 

It’s important to note that certain events or incidents can invalidate your warranty terms or duration. To keep your solar panel warranty valid, consider these measures:

  • Regular maintenance: Follow the manufacturer’s recommended maintenance guidelines to keep your solar panels in optimal condition. This may include periodic cleaning, inspection, and servicing.
  • Avoid unauthorized modifications: Refrain from making any unauthorized modifications or alterations to your system.
  • Monitor performance: Keep track of your solar panel system’s performance over time. By monitoring elements like energy production and system output, you can identify issues early and schedule the necessary repairs as soon as possible. 

Be sure to familiarize yourself with your solar panel warranty terms and conditions. It’s also a good idea to understand the claims process in the event you need to file a claim.

Claims Process and Customer Support

If you ever experience issues with your solar panel, and the warranty covers those issues, you’ll need to submit a claim. Manufacturers often have different procedures, and navigating these can be tricky. Here are a few general tips to keep in mind: 

  • Review terms and conditions: It’s essential to carefully read the terms and conditions of your solar panel warranty. Pay close attention to coverage duration, exclusions, and guarantees. When filing claims, knowing what is (and isn’t) covered is helpful. 
  • Keep documentation: The manufacturer may ask for certain documentation to validate warranty coverage. Keep a record of anything relevant, such as purchase receipts, performance data, and installation and maintenance records. 
  • Document the problem: Besides maintaining a paper trail, document the current issue carefully. Provide detailed descriptions, including when the problem started and how it affects performance. 
  • Cooperate with the warranty provider: The manufacturer or warranty provider may request additional information (such as photographs) throughout the claims process. They may also schedule an inspection. Following their instructions can help make the process go smoothly.

What to Look for in a Warranty

The solar panel warranty plays a huge role in your overall investment. If anything goes wrong, the warranty will determine your coverage. When deciding between providers, here are a few key things to look for:

  • Coverage amount/​duration: You want long-term coverage from your warranties. Photon Brothers offers 25-year production guarantees, surpassing most traditional warranties.
  • Product quality: A lengthy warranty means little if the company doesn’t stand by its products. At Photon Brothers, we use high-quality, US-made products, such as REC or Silfab panels.
  • Customer support: How much support does the company offer? If you’ve tried reaching out and struggled to receive a response, that’s a sign that you may have difficulty submitting warranty claims. 
  • Reliable installer: While the solar market is booming, many new companies are going out of business, so it’s important to work with an established installer in your area. Otherwise, you could be stuck footing the labor bill if you need repairs, even if your labor warranty is still valid. 

At the end of the day, you need to work with a company that you can trust. This means a reputable installer with a history of producing high-quality products and honoring their warranties, such as Photon Brothers. We’ve been in business for well over 10 years, and we’ve built a 5‑star reputation throughout the process.
