JA Solar Responds to U.S. Department of Commerce's Final Decision on Anti-Dumping Tariffs on Chinese Solar Products

Under the ruling, solar modules assembled in China from cells produced in third countries do not fall within the scope of the duties.

SHANGHAI, China, Oct. 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 responded to
the final determination by the U.S. Department of Commerce ("DOC") on
imposing anti-dumping duties on China-produced solar products.

In its final decision, the DOC determined that crystalline silicon
photovoltaic ("PV") cells produced in China, whether or not assembled into
modules, would be subject to antidumping and countervailing duties. Under
the ruling, solar modules assembled in China from cells produced in third
countries do not fall within the scope of the duties.
The U.S. International Trade Commission ("ITC") will make its final
determination on or before November 23, 2012.

Pursuant to the DOC's determination, PV cells produced in China by JA Solar
will be subject to an antidumping duty of 25.96% and a countervailing duty
of 15.24%.

Jonathan Pickering, president of JA Solar USA, commented, "We are pleased
that the dispute is coming to a close and that the scope of the
investigation was not expanded. JA Solar cooperated fully with the DOC
during its investigation, and we continue to state our case to the ITC."

Mr. Pickering continued, "We remain focused on addressing our customers'
need for high-quality, high-performance products, and we're determined to
play an active role in the rapid growth of the U.S.
market."

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
