What is a typical warranty period for solar panels?

The typical warranty period for solar panels generally aligns with the 25 years for performance and around 10 years for materials, which is indicative of the industry's standards.

Manufacturers commonly provide a performance warranty that guarantees that the panels will maintain a certain level of power output over 25 years, ensuring that they will produce at least 80% of their original output by the end of the warranty period. This long duration reflects the expected lifespan of solar panels and gives consumers confidence in the investment. The warranty on materials or workmanship, usually spanning around 10 years, covers potential defects in the panels or issues arising from manufacturing processes.

This differentiation in warranty duration highlights the emphasis placed on performance guarantees, reinforcing the reliability and longevity of solar technology. Solar panel technology has matured, leading to increased confidence in the resilience and efficiency of solar products over time.
