WUXI, China, Dec. 18, 2012

WUXI, China, Dec. 18, 2012 /PRNewswire/ -- Suntech Power Holdings Co., Ltd.
(NYSE: STP), one of the world's largest producers of solar panels, today
announced that its solar modules have passed the Blowing Sand Test based on
DIN EN 60068-2-68 LC2 by SGS, the world's leading inspection, verification,
testing and certification company. The SGS test result confirms that Suntech's
solar modules are suitable for solar installations in desert regions.

"As solar energy proliferates around the world, it is critical to develop
solar modules that can perform optimally in different terrains and
environments. For our customers, passing the Blowing Sand Test confirms that
Suntech's solar modules are well-suited for desert regions and can withstand
high-velocity sand and windy conditions," said Dr. Stuart Wenham, Suntech's
Chief Technology Officer. "Quality assurance is an integral part of Suntech's
value proposition, and we pride ourselves on rigorous testing procedures to
ensure that our customers have a product that can operate for 25 years
anywhere on the globe."

Dr. Daniel Deng, Technical Manager for SGS said, "SGS follows an internally
developed test procedure and can customize specifications like sand
homogeneity, sand concentration, sand shape and wind speed according to single
selected deserts. We were extremely impressed with the quality of Suntech's
solar modules and their ability to withstand the Blowing Sand Test that
replicates the conditions of a heavy desert sandstorm. Endurance testing is
critical in order to understand the reliability and longevity of solar panels
in real world conditions."

To determine the effects on solar panels of dust and sand suspended in air,
SGS's Desert Dust Test simulates the erosion effects of high-velocity sand
particles within dust chambers. Pulses of compressed air are blown through a
manifold located in the bottom of a collection trough, forcing dust up and
over the solar module. Suntech solar modules passed the maximum power
determination, the insulation test and the wet leakage current test.

State-of-the-art manufacturing and quality testing lies at the core of
Suntech's business, which enables it to deliver high-quality solar products to
customers at an affordable price. Suntech's quality control program features
52 tests and checks throughout the cell and module manufacturing process. Once
fully assembled, all Suntech modules undergo a final performance test and are
categorized based on power and current production. In addition, Suntech solar
panels undergo the Combined Cycle Testing at its advanced testing laboratories
that simulate long-term environmental stress conditions. Suntech's rigorous
review process ensures that it delivers only the highest quality products to
our customers.
