Suntech Power Holdings Co., Ltd.

We are one of the leading solar energy companies in the world as measured by production output in 2009, with leading positions in key solar markets. Since we commenced business operations in May 2002, we have grown rapidly to become the world’s largest manufacturer of crystalline silicon PV cells and modules in 2009, based on production output. We believe that we are a key player in the rapidly expanding solar power industry globally. We design, develop, manufacture and market a variety of PV cells and modules, including a broad range of value-added BIPV products. Our products are used to provide reliable and environmentally friendly electric power for residential, commercial, industrial and public utility applications in various markets worldwide. We also provide PV system integration services to customers in China and the United States, and are expanding into the development of utility scale solar power systems.

We sell our products in various key solar energy markets worldwide including Germany, Italy, the United States, China, South Korea, Spain, the Middle East, Australia and Japan. We currently sell our products primarily through a selected number of value-added resellers such as distributors and system integrators and to end users such as project developers that have particular expertise and experience in a given geographic or applications market. We have established local sales offices in our key markets such as Spain, Germany, Italy and the United States, and have also been actively establishing sales offices and regional offices in Switzerland, Australia, Japan and South Korea in Asia Pacific, and the United Arab Emirates in the Middle East. We plan to continue to increase our direct sales activities across all regions. We believe that our local sales offices will enhance our ability to localize customer service and support, which will help foster closer relationships with our key customers.

We believe that we have been able to grow rapidly because of our ability to capitalize on the PV market’s demand for high efficiency products at low cost per watt. Our strong research and development capabilities have enabled us to develop advanced process technologies and manufacture, cost-effectively and on a large scale, PV cells and modules with high conversion efficiencies. Conversion efficiency rates measure the ability of PV products to convert sunlight into electricity. As of December 31, 2009, the average conversion efficiency rates of our monocrystalline and multicrystalline silicon PV cells were 17.40% and 15.69%, respectively. In 2009, we continued commercial production of PV cells utilizing Pluto technology, a high efficiency PV technology that allows us to achieve conversion efficiency rates in the range of 18.0% to 19.0% on PV cells manufactured with monocrystalline silicon wafers and 16.5% to 17.5% on PV cells manufactured with multicrystalline silicon wafers. We had achieved 100 MW of Pluto cell production capacity by December 31, 2009, and plan to accelerate retrofitting of existing production lines to Pluto technology in order to achieve 450 MW of Pluto cell production capacity by mid 2010.

We believe our China-based design, development and manufacturing facilities provide us with several competitive advantages, including access to low-cost technical expertise, skilled labor and facilities. We leverage our cost advantages by optimizing the balance between automation and manual operations in our manufacturing processes, which we believe lowers our operating costs and capital expenditures and enables us to expand our manufacturing capacity in a cost-effective manner. We continuously evaluate and adjust our combination of automated and manual operations in our manufacturing processes in order to optimize our cost structure while improving our manufacturing yields and quality.
