Hanwha SolarOne Co., Ltd. (Hanwha SolarOne), a leading global manufacturer of silicon ingots, wafers and photovoltaic ("PV") cells and modules, announced that it will extend its materials and workmanship warranty from two to five years to 12 years for modules manufactured in China. Hanwha SolarOne believes that it offers the longest warranty protection in the entire global solar industry. Hanwha SolarOne will also replace its existing warranty for power generation capacity with an improved 25-year linear warranty.
"Hanwha SolarOne is pleased to offer warranties that reflect the exceptional quality and reliability of our PV modules," said Ki-Joon Hong, chief executive officer of Hanwha SolarOne. "We believe that the solar industry has a very bright future ahead of it, and we are committed to being a trusted long-term partner of our customers — providing them with quality products and exceptional service every step of the way."
Hanwha SolarOne plans to apply the improved warranties to its modules sold after January 1, 2012. Under the new 25-year linear warranty, Hanwha SolarOne guarantees no less than 97% of the nominal power generation capacity for its typical poly PV modules and 96% of the nominal power generation capacity for its typical mono PV modules in the first year, and an annual output degradation of no more than 0.7% for both poly and mono PV modules thereafter. By the end of the 25th year, the actual power output shall be no less than 82% of the nominal power generation capacity.
