SHANGHAI, China, Nov. 12, 2012 -- 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, today
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

cost or demand on space.

produce industry-leading output at competitive cost levels," said Dr.
