Hoku Corporation, Hawaii's clean-energy technology company, was founded in 2001. The company initially focused on developing and bringing to market its proprietary fuel cell membrane technology and worked with customers including Nissan, Sanyo and the U.S. Navy.
As Hoku began to diversify its clean-energy products and services, the company was able to find a unique position in the global solar industry with its two complementary and wholly-owned subsidiaries: Hoku Solar and Hoku Materials.
Hoku Solar remains one of Hawaii’s oldest, most experienced solar companies, specializing in investment-grade solar projects for commercial, industrial and utility users in Hawaii - including large-scale rooftop and ground-mounted photovoltaic (PV) arrays for businesses, institutions and government clients. Hoku Materials manufactures, markets and sells solar-grade polysilicon for manufacturers of PV products. Polysilicon is the primary raw material used to manufacture PV cells and modules.
Hoku Corporation is a majority-owned subsidiary of Tianwei New Energy Holdings Co., Ltd. (TWNE), a leading manufacturer of renewable energy products in China.
