JA Solar Modules Pass Salt Mist Corrosion and Sulfur Dioxide Corrosion Tests
Conducted by TUV NORD

SHANGHAI, China, Feb. 25, 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
all of its PV module series have successfully passed salt mist corrosion and
sulfur dioxide corrosion tests. The independent tests were conducted by TÜV
NORD AG, a leading multinational provider of inspection, product testing and
certification services. The test results confirm that JA Solar's products
offer exceptional reliability even in severe environments.

High salt concentration and humid conditions are associated with coastal
regions and certain pastoral farming areas. Prolonged exposure to these
conditions may corrode module components including the frame, junction box and
glass, causing lower module power output. Conducted against IEC61701 standards
for power output, ground continuity, wet leakage current, insulation
resistance and appearance, the salt mist corrosion test revealed that JA
Solar's modules are in conformance with the aforementioned standards and are
able to maintain high performance even under extreme conditions.

JA Solar's modules also passed a sulfur dioxide corrosion test. High sulfur
dioxide concentration, common in volcanic areas and around chemical
manufacturing facilities,can cause corrosionin PV modules and decrease
energy output. JA Solar's modules were tested against DIN EN ISO 6988-1995
standards, involving exposure to sulfur dioxide for a period of 480 hours, and
were tested for power output degradation, ground continuity, wet leakage
current, insulation resistance and appearance. JA Solar's modules successfully
passed the test and showed less than 5% power output degradation.

"We are delighted with the strong performance of JA Solar's modules under TÜV
NORD's stringent testing, and we pride ourselves on our products' ability to
function reliably under the most challenging conditions," said Mr. Yong Liu,
CTO of JA Solar. "Our commitment to continuous technological innovation is
vital to our ability to provide our customers with high-performance,
high-efficiency and high-reliability products."
