Solar panel warranties protect your solar investment. That’s why it’s key to understand what types of warranties exist and how they work.
There are two different kinds of warranties that ensure your panels are covered, but each have their differences in exactly what they cover you for.
Which Types Of Solar Panel Warranties Exist?
Solar panels come with two warranties: a product and a performance warranty. Both warranties are offered by the panel manufacturer, so it’s the responsibility of the manufacturer to ensure warranty conditions are met.
Product warranties are very straight forward.
If, due to no fault of your own, a solar panel you have bought stops working or performs poorly, you’re entitled to a replacement.
For quality solar panels you can expect a product warranty of 10-25 years.
The performance warranty promises that the performance of your solar panels doesn’t fall under a certain point.
The performance warranty for quality solar panels will typically ensure that your panel’s performance is 90% at 10 years and 80% or more at 25 years.
This is one major reason to choose quality solar panels because they come with a better performance warranty.
What’s The Difference Between Product And Performance Warranty?
You may think the product and the performance warranty sound very similar. You might even think that if a panel fails and your system performs below the promised level, you’re entitled to replacement.
If you think that, you’re right.
What most people aren’t aware of when it comes to solar panel warranties
If a panel fails or its output falls below the promised level after the product warranty ends, but still during the performance warranty, the manufacturer will have to repair or replace it.
This means panels that come with a 25-year performance warranty are ensured for their entire lifetime.
If at any point during their lifetime your system’s output falls below the promised performance, it is covered by the performance warranty.
Why it pays to get a 25 year performance warranty
This is vital to understand since many people assume their panels aren’t covered for more than the product warranty. This is not true.
If one of your solar panels fails after 15 years, it will affect the performance of your solar system.
If the performance of your solar system isn’t as high as promised by the performance warranty, your panel manufacturer is obligated to repair or replace the failed panel.
Pro-Tip: You don’t need a solar monitoring system to send proof of your system’s performance to the manufacturer. This can be done by your solar installer.
Why do Product Warranties matter?
Why does the manufacturer offer two different warranties when the performance warranty covers both product and performance?
The performance warranty does not cover any panel replacement or repair when your system’s performance falls below what you expect, but is higher than what the performance warranty guarantees.
