First Solar is the world's largest thin-film photovoltaic solar module manufacturer and the leading U.S.-headquartered solar manufacturer, specializing in proprietary cadmium telluride technology that offers superior performance in high-heat and humid climates while avoiding dependence on Chinese silicon supply chains. The company manufactures Series 6 Plus and Series 7 modules through a proprietary fully integrated production process at facilities across the United States, Malaysia, Vietnam, and India, selling primarily to system developers, independent power producers, utilities, and corporate energy buyers for utility-scale projects. First Solar generates revenue through direct module sales to project developers, with earnings supported by government incentive programs, tax credits, and growing demand driven by renewable energy targets and long-term power purchase agreements, while differentiating through advanced efficiency, durability, responsible sourcing practices, and integrated domestic manufacturing capacity.
