What Warranties Should I Look for While Purchasing Solar Panels?

 

This question is part of the Super Big Solar Panel FAQ from Solar Mango, where expert answers to over 100 important questions on solar panels are provided.

 

Overall, buyers look for two kinds of warranties:

  • Product warranties
  • Performance warranties

Product warranty essentially provides a guarantee about the overall life and robustness of the solar panel to last for 25 years. This is a guarantee that is not unlike what you get as standard product warranty for many conventional products.

What you should be more interested in the context of solar panel warranties are the Performance Warranties, which guarantee a minimum performance/output from the solar panels during its lifetime.

There are two performance warranties that come with solar panels

  • Standard Warranty
  • Linear Warranty

The Standard Warranty gives you a minimum output per Wp for a fixed period, while the Linear Warranty clearly stipulates the minimum output from the solar panel for each of the 25 years.

Overall, the Linear Warranty can give you a much higher output over the 25 year period than the Standard Warranty, even if does cost slightly higher.

So, go for the Linear Performance Warranty.
