First Solar, Inc.

First Solar, Inc. is an American solar technology company and a global provider of responsibly produced, eco-efficient solar modules. The company's mission is to provide cost-effective solar solutions that lead the world's sustainable energy future, enabling a world powered by clean, affordable solar electricity. Headquartered in Tempe, Arizona, U.S., First Solar focuses on advancing utility-scale decarbonization of power grids.

First Solar specializes in the design, manufacture, and sale of advanced thin-film photovoltaic (PV) modules, utilizing Cadmium Telluride (CdTe) semiconductor technology. These modules are employed in various applications, including ground-mount, carport/canopy, and floating solar systems, primarily for utility-scale projects. The company serves system developers, independent power producers, utilities, and commercial and industrial clients globally. First Solar also operates the industry's only global high-value PV module recycling services.

Led by CEO Mark Widmar, First Solar holds a unique market position as the only US-headquartered company among the top global solar manufacturers that does not manufacture in China. The company has made significant investments in expanding its domestic manufacturing capacity, with facilities in Ohio, Alabama, and Louisiana, and anticipates opening a finishing facility in South Carolina in late 2026. While First Solar reported record first-quarter revenue in 2026, it has also faced recent class-action lawsuits regarding its capacity to manage U.S. tariff policy impacts and lower-than-expected FY 2026 revenue guidance. In May 2023, First Solar acquired Evolar, a European company specializing in perovskite technology.
