First China-based Solar Company to Pass Blowing Sand Test

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

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
