Yingli Green Energy Holding Company Limited is a vertically integrated photovoltaic (PV), product manufacturer worldwide.
The Company designs, manufactures and sells PV modules, and design, assemble, sell and install PV systems. Its products and services substantially cover the entire PV industry value chain, ranging from crystalline polysilicon ingots and wafers, PV cells and PV modules to the manufacture of PV systems and the installation of PV systems. The Company sells PV modules under its own brand names, Yingli and Yingli Solar, to PV system integrators and distributors located in various markets around the world, including Germany, China, the United States, Greece, Spain, Italy, France, India, Japan, the Netherlands, the United Kingdom, Israel, Korea and Belgium.
Polysilicon Ingots and Blocks
A polysilicon ingot is formed by melting, purifying and solidifying polysilicon feedstock into a brick-shaped ingot. The Company produces 400 kilogram, 420 kilogram, 480 kilogram and 500 kilogram multicrystalline polysilicon ingots, which account for approximately 90% of its ingots. The polysilicon ingots are then cut into blocks. Its polysilicon blocks are generally available in cuboid with the same face the size of 156 millimeters x 156 millimeters and different heights. The Company uses its polysilicon blocks to produce polysilicon wafers.
A PV cell is a device made from a polysilicon wafer that converts sunlight into electricity by a process known as the photovoltaic effect. The conversion efficiency of a PV cell is the ratio of electrical energy produced by the cell to the energy from sunlight that reaches the cell. The conversion efficiency of PV cells is determined to a large extent by the quality of wafers used to produce the PV cells, which is, in turn, determined by the mix of different types of polysilicon raw materials used in the ingot casting process. In addition, the Company has commercialized 600 megawatts of monocrystalline production capacity for each of monocrystalline ingots and wafers, cells and modules in Baoding, Hebei Province.
A PV module is an assembly of PV cells that are electrically interconnected, laminated and framed in a durable and weatherproof package. Most of its PV modules are made with PV cells produced by the Company. Its PV modules are made with a frame design that enhances their ability to withstand wind and vibrations. A majority of PV modules produced by the Company has outputs ranging from 150 to 270 watts.
Integrated PV Systems
The Company produces PV systems and also design, assemble, sell and install stand-alone PV systems for lighting systems, mobile communication base stations and residential applications. In order to focus on its PV products and their components, it no longer produces controllers, inverters and other components used in its PV systems but instead source them from third-party manufacturers and sell them to the customers as part of its PV systems. The Company installs these systems on-site for the customers. For its PV systems, the Company works with the customers on-site to design, install, test and oversee the system start-up.
The Company competes with Sharp Corporation, SunPower Corporation, First Solar, Inc., SolarWorld AG, Renewable Energy Corporation, Suntech Power Holdings Co. Ltd. and Trina Solar Limited.
