The new warranty terms are introduced retroactively as of January 1st 2017 and complement the 25-year linear performance guarantee that was already introduced in 2012. By extending the product warranty to 15 years, manufacturer Winaico stays ahead of the market with longer duration of protection to the customers from material or production defects in solar modules. The 25-year linear performance guarantee ensures a performance of at least 97 percent of rated performance in the first year, and annual power degradation no more than 0.7 percent in the following 24 years.
According to Winaico all modules are produced in their own manufacturing plants at the headquarters in Taiwan, the firm controls all stages of the production process of each module to ensure top quality for our modules.
