JA Solar Modules Pass PID Tests Conducted by TUV SUD

SHANGHAI, China, Jan. 23, 2013 (GLOBE NEWSWIRE) -- 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
its multicrystalline and monocrystalline PV modules successfully passed
Potential Induced Degradation (PID) tests conducted by TÜV SÜD, one of the
world's leading providers of testing and certification services.

JA Solar's modules were tested under extreme conditions, including
temperatures of 85 degrees Celsius, 85% relative humidity, and 1,000 volts of
system bias voltage, for a duration of 96 hours. Test results showed less than
1% power degradation in the modules.

The solid performance of JA Solar's modules stems from the Company's adoption
of PID-resistant solar cells in the module-manufacturing process. The
PID-resistant cells significantly decrease undesired power loss caused by high
system voltages, lengthen the lifespan of modules, and ensure stable operation
in adverse weather conditions.

"The strong performance of our modules in TÜV SÜD's PID tests represents
another milestone in JA Solar's efforts to produce industry-leading products
with superior stability," said Mr.Yong Liu, CTO of JA Solar. "Customers value
JA Solar for the reliability and efficiency of our product offering, and our
persistent focus on technological innovation ensures that we meet and exceed
their high expectations."
