What is the warranty on Yingli solar products?

Yingli Solar typically offers a limited warranty for their solar products, which is generally divided into two main components: the product warranty and the performance warranty. The product warranty usually spans about ten years, covering defects in materials and workmanship. On the other hand, the performance warranty often guarantees that the solar panels will produce a certain percentage of their rated power output over a specified period, commonly up to twenty-five years. This means that Yingli Solar aims to ensure the panels maintain a specified level of efficiency throughout their operational life. However, warranty specifics can sometimes vary based on the product line or regional offerings. Therefore, it is advisable to refer to the official Yingli Solar website or the product documentation for the most accurate and detailed information regarding the warranty for specific products.
