Suntech Power Internal Controls

Suntech Power Holdings Co., Ltd. (NYSE:STP) one of the world's leading manufacturers of photovoltaic (PV) cells and modules, today announced that it has met the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 ("SOX") regarding internal controls over financial reporting as stated in its annual report for the year ended December 31, 2006.

''This successful completion of the SOX 404 audit represents a strong indication of our long-standing commitment to the highest standards of corporate governance,'' said Dr. Zhengrong Shi, Suntech's Chairman and CEO. ''The internal control systems established as part of this have also enabled us to achieve significant growth in production and sales.''

Section 404 of SOX requires that companies listed on U.S. stock exchanges file an internal control report within the annual report that states management's responsibility for internal controls of financial reporting, and includes an assessment of the effectiveness of the controls and an external audit of the reliability of the internal control structure and procedures. Compliance with SOX Section 404 is a testament to the veracity and transparency of all financial information that a company discloses.

''Suntech is proud to have achieved official approval of our internal financial controls and processes. Our extensive efforts to comply with SOX 404 as a public company demonstrate our dedication to corporate transparency,'' said Amy Zhang, Suntech's CFO. ''The rigor of SOX compliance has also been an excellent opportunity to improve our business processes and increase back- office efficiency.''
