HANWHA SOLARONE announces latest Modules to receive UL, MCS and TUV quality certifications

Shanghai (ots) - Hanwha SolarOne Co., Ltd. ("Hanwha SolarOne" or
the "Company") (NASDAQ: HSOL), a vertically integrated manufacturer
of silicon ingots, wafers and photovoltaic ("PV") cells and modules
in China, today announced quality certifications for its new
crystalline solar modules in the British, North American, and German
markets. The new certifications come from three independent quality
certification bodies including U.S.-based Underwriters Laboratories
Inc. ("UL"), UK-based Microgeneration Certification Scheme ("MCS"),
and Germany's Technischer Überwachungs-Verein [Technical Inspection
Association] ("TÜV Rheinland").

To date, Hanhwa SolarOne has maintained a strong portfolio of UL-
certified crystalline modules. Long recognized as a guarantee of
high performance, safety, environmental friendliness and quality,
certification from UL is essential for products sold in the U.S.
market. The Company's most recent certifications include its X-tra
serial and Black Diamond modules, as well as some from its standard
[normal? xxx] line.

The Company has also validated a significant number of modules
through TÜV Rheinland, recognized across Europe as the highest
guarantee of product safety and performance. Similarly, for the UK
market, products bearing the MCS mark are likely to be seen as the
preferred option in the market place. MCS is also linked to
financial incentives which include feed in tariffs.

Dr. Peter Xie, President and Chief Executive Officer of Hanwha
SolarOne, commented, "I am very pleased to announce the latest
international certification achievements of our newest crystalline
modules. As we grow into a global company, we continue to make every
effort to ensure the market-leading safety, reliability and
performance that our brand has become known for, is extended to all
of our customers. The UL certification extends even more of our
high-quality products to the North American market, while the MCS and
TÜV Rheinland labels will enhance our offerings in the United Kingdom
and EU. The certifications are a great accomplishment, and are a
strong signal of our company's commitment to expanding in these
markets."
