SunEdison Companies
SunEdison, Inc.
SunEdison's solar materials group produces granular polysilicon, silicon-crystal ingots, silicon wafers, and specifies the production of solar cells and solar modules. It produces granular polysilicon in purities usable in the solar and semiconductor industries. The granular polysilicon is produced in Pasadena, Texas, and, through a joint venture with Samsung and SunEdison Semiconductor, in Ulsan, Korea. The granular silicon is used for SunEdison's own silicon-crystal manufacturing, and for sales to third-party solar and semiconductor crystal-manufacturing companies. The division also has a plant in Portland, Oregon acquired from Solaicx in 2010, which produces silicon-crystal ingots using the "continuous crystal growth" technology, enabling the production of low-cost wafers for high-efficiency solar cells. The ingots are sliced into wafers in Malaysia. SunEdison and its subsidiaries and joint-venture partners also manufacture the solar cells used in its modules. Its solar modules are assembled by contract manufacturers in Malaysia, Mexico, Taiwan, Korea, and China which use SunEdison technology, meet SunEdison's strict specifications, and use SunEdison's quality control systems.
SunEdison's solar power group plans, designs, develops, finances, underwrites, builds, installs, operates, monitors, and maintains large-scale solar energy and wind energy systems and plants for commercial customers, including numerous national retail outlets, shopping centers, businesses and corporations; government agencies and other public-sector customers; and utilities and other power companies. Through an extensive dealer network, it also provides complete solar systems and services for residential homeowners. Through its financing services and partners, SunEdison offers commercial and residential customers the opportunity to install a solar system for no upfront costs, with predictable cost-effective energy rates over the life of the system contract. The company also continues its longstanding research and development to create innovations, cost reductions, and performance enhancements in solar-energy systems technology. SunEdison produces energy via its numerous power plants, and also manages numerous solar power plants worldwide.
