Evergreen Solar, Inc. engages in the development, manufacture, and marketing of solar power products primarily in the United States and Europe. It utilizes its proprietary String Ribbon technology process to produce multi-crystalline silicon wafers by growing thin strips of multi-crystalline silicon that are then cut into wafers. These wafers are the primary components of photovoltaic cells that are used to produce solar panels. The company principally offers solar wafer, a flat piece of crystalline silicon that can be processed and assembled into a solar cell; solar cell, a device made from a silicon wafer that converts sunlight into electricity; and solar panel, an assembly of solar cells that are electrically interconnected and laminated for electric power generation, such as on-grid and off-grid generation. Evergreen sells its products through distributors, systems integrators, project developers, and value-added resellers. It has a strategic partnership agreement with Q-Cells AG.
