YGE

Yingli Green Energy Holding Company Limited

We are one of the leading vertically integrated photovoltaic, or PV, product manufacturers in the world. We design, manufacture and sell PV modules, and design, assemble, sell and install PV systems. With an overall annual manufacturing capacity of 600 megawatts for each of multicrystalline polysilicon ingots and wafers, PV cells and PV modules as of the date of this annual report, we believe we are currently one of the largest manufacturers of PV products in the world as measured by annual manufacturing capacity. With our in-house polysilicon manufacturing capacity, which started trial production in late 2009, our current products and services substantially cover the entire PV industry value chain, ranging from the manufacture of polysilicon, multicrystalline polysilicon ingots and wafers, PV cells and PV modules to the manufacture of PV systems and the installation of PV systems. We believe we are one of the largest PV companies in the world to have adopted a vertically integrated business model. Our end-products include PV modules and PV systems in different sizes and power outputs. We sell PV modules under our own brand names, Yingli and Yingli Solar, to PV system integrators and distributors located in various markets around the world, including Germany, Spain, Italy, Greece, France, South Korea, the United States and China.

In 2002, we began producing PV modules with an initial annual manufacturing capacity of three megawatts and have significantly expanded production capacities of our PV products in the past seven years to the current level. We currently plan to expand our overall annual manufacturing capacity of each of polysilicon ingots and wafers, PV cells and PV modules to one gigawatt by the end of 2010 by building 300 megawatts of monocrystalline PV manufacturing capacity and an additional 100 megawatts of multicrystalline PV manufacturing capacity. In addition, through Fine Silicon, our in-house polysilicon production subsidiary, we expect to have a polysilicon production capacity of 3,000 tons per year by the end of 2010.
