JA Solar Holdings Co., Ltd.(Nasdaq:JASO), ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, announced that it has launched its new 6-inch full-square monocrystalline module series. The modules have been certified by TUV Rheinland, one of the world's leading providers of technical services, as having a maximum conversion efficiency of 16.82% and a maximum power output of 275W. JA Solar will commence mass production of the new product offering this month.

With the adoption of JA Solar's high-efficiency 6-inch full-square monocrystalline solar cells and proprietary module encapsulation technologies, the new 6-inch full-square modules produce a mainstream power output of 270W, making them the most powerful modules using P-type solar cells in a 60-cell format on the market. On average, the modules produce an annual accumulated output 4% higher than comparable models, allowing PV systems to generate superior performance with no additional installation cost or demand on space.

"The 6-inch module series is another significant step in our efforts to produce industry-leading output at competitive cost levels," said Dr. Peng Fang, CEO of JA Solar. "The new modules' unparalleled output, outstanding conversion efficiency, and competitive cost make them a clear leader in the 60-cell format and an ideal solution for the burgeoning rooftop market."
