First Solar is the world's largest thin film photovoltaic (PV) solar module manufacturer and the largest PV solar module manufacturer in the Western Hemisphere, producing cadmium telluride (CdTe) thin film modules through a fully integrated, continuous manufacturing process that does not rely on Chinese crystalline silicon supply chains. Technology is developed at R&D labs in California and Ohio, and has been sold in excess of 93 GW of modules worldwide. The company sells to utility-scale power generation markets where PV solar can provide a competitive levelized cost of electricity.
First Solar operates manufacturing facilities in the United States, Malaysia, Vietnam, and India, backed by more than $2 billion in cumulative R&D investments over 20 years. Its CdTe technology offers a superior temperature coefficient in high-insolation climates, better spectral response in humid environments, improved partial shading response, and immunity to cell cracking versus conventional crystalline silicon modules. The company provides a limited power output warranty of up to 30 years covering module power output beginning at 98% of labeled rating.
