Founded in 1999, First Solar is a leading American solar technology company and global provider of responsibly produced eco-efficient solar modules advancing the fight against climate change. The company is unique among the world’s ten largest solar manufacturers for being the only US-headquartered company and not manufacturing in China. First Solar’s advanced thin film photovoltaic (PV) modules represent the next generation of solar technologies, providing a competitive, high-performance, lower-carbon alternative to conventional crystalline silicon (c-Si) PV panels.

First Solar has the Western Hemisphere's largest solar manufacturing footprint in Ohio, USA, with a third factory set to come online in the state in the first half of 2023 and a new factory, the company's fourth American manufacturing facility, expected to be commissioned in the US Southeast in 2025. The company will have a global annual manufacturing capacity of over 20 gigawatts (GW) by 2025, with a footprint that spans the US, India, Malaysia, and Vietnam. First Solar thin film PV modules are produced using a fully integrated, continuous process under one roof that does not rely on Chinese crystalline silicon (c-Si) supply chains. Its proprietary, vertically integrated process transforms sheets of glass into fully functioning solar panels in approximately four hours with a combination of highly skilled workers, Industry 4.0 architecture, machine-to-machine communication, artificial intelligence, and Internet of Things connectivity.
