How do solar companies fulfill their warranties? Do they change one panel if it breaks or is underperforming? How long will my system be out of commission if this happens?

Solar panels will typically come with two types of warranties in order to safeguard your solar investment in the unlikely case of a problem. These two types of warranties are the manufacturer's warranty and the product warranty.

The manufacturer's warranty will cover your solar panels against things like defects and premature wear-and-tear. They typically last about 10-12 years. If you need to have a panel replaced, the warranty will cover the panel itself, and may also cover shipping and labor.

The product warranty covers the power output of your solar panels. These warranties are typically valid for 25-30 years, and guarantee that power production of your panels will not fall below a certain percentage of their original output - for example, no less than 80% of the original efficiency by the 25th year.

In the case of both types of warranties, you should check with the manufacturer to find out exactly what the details are. Also check the warranty for details about how long it will take for you to get the new one. How much of the work and costs will you be responsible for? Your installer should be able to give you some idea as well.
