JA Solar Holdings Co., Ltd. manufactures high-performance solar cells based in China. The company sells its products to solar module manufacturers who assemble and integrate its solar cells into modules and systems that convert sunlight into electricity. It sells its products to customers primarily in China, Germany, Sweden, Spain, South Korea and the United States.
The company focuses on solar cell design and manufacturing, a stage in the solar power industry value chain. It designs, manufactures, and markets solar cells, which are made from specially processed silicon wafers and convert sunlight into electricity through a process known as the photovoltaic effect.
The company produces only monocrystalline solar cells as all of its silicon wafer supplies are monocrystalline. As of December 2006, it sold a total of approximately 10.9 million 125 mm × 125 mm solar cells with a total power output of approximately 26.2 MW.
Format: The company produces solar cells with a format of 125 mm × 125 mm with maximum power of 2.60 watts and an optimum operating voltage of 0.62v. It produces different sizes of solar cells by making minor adjustments to the equipment used in its manufacturing lines.
Cell Thickness: One of the company’s research and development projects is focused on refining process technologies for ultra-thin wafers. The average thickness of the silicon wafers from its suppliers is in the range of 210-230 microns. The company is capable of processing silicon wafers that are as thin as 180 microns.
The company purchases all of its wafer supplies from Jinglong Group. It has also entered into a 31-month wafer supply agreement with ReneSola in September 2006 and a 54-month wafer supply agreement with M.SETEK in December 2006.
