Founded in 1973, Solarex is the first organization to have applied photovoltaic technology to commercial needs on Earth. As a wholly owned subsidiary of BP Amoco, Solarex (now called BP Solar) is the largest manufacturer of polycrystalline silicon PV modules and cells and the leader in the manufacture and commercialization of single and tandem junction thin film silicon technology and modules. BP Solar has ISO 9001-certified manufacturing facilities in Australia and the U.S., and power systems operating on every continent. BP Solar has over twenty-five years of research, development and manufacturing experience in advanced polycrystalline silicon technology. BP Solar’s polycrystalline solar cells are manufactured with SEMIX™ process cast silicon which gives them attractive large crystal grains and low impurities. The cells are covered with a highly conductive silver paste grid, backed with a strong, conductive aluminum layer and topped with an anti-reflective coating to enhance efficiency. Every cell is tested and categorized by its output current at a reference voltage. Power losses in modules due to mismatched cells are virtually eliminated.
