Hanergy Holding Group Ltd. is a multinational clean energy company, as well as the world's largest thin-film solar power company, committed to changing the world by clean power. Established in 1994, the company is headquartered in Beijing and has more than 10,000 employees. It has branches in provinces all over China as well as in the Americas, Europe and the Middle East, Asia-Pacific, Africa and other regions, with core businesses covering hydropower, wind power and thin-film solar power.

At present, Hanergy's total installed capacity of hydropower projects exceeds 6GW, and its total installed capacity of wind power projects is 131MW. In the field of solar power, the company engages in the integration of the entire thin-film value chain, covering R&D, high-end equipment manufacturing, thin-film solar module production and construction of thin-film solar power plants. It has invested in the construction of thin-film solar R&D and manufacturing bases throughout China with a total production capacity of 3GW. In addition, Hanergy has entered into thin-film solar power plant construction agreements that total a capacity of about 10GW. Through global technical integration and independent innovation, Hanergy has become a world leader in thin-film solar technology. The maximum research conversion efficiency of its copper indium gallium selenide (CIGS) technology has reached 21%, as certified by Germany's Fraunhofer Institute for Solar Energy Systems (ISE), and its gallium arsenide (GaAs) technology's research conversion efficiency has reached 30.8%, as certified by the U.S.'s National Renewable Energy Laboratory (NREL).

Thin-film solar technology enables cutting-edge features such as flexibility, light weight, superior low light performance, and diversified color and shapes. These unique qualities make it adaptable to a wide range of applications, including Building Integrated Photovoltaics (BIPV), flexible rooftop, residential power, automobile power, electronics, as well as other consumer and specialty products.
In February 2014, Hanergy was selected by theMIT Technology Reviewas one of the 50 smartest companies in the world. It was the only Chinese energy company honored with the award.
