Overview
Hanergy is a Chinese renewable-energy company headquartered in Beijing and historically controlled by entrepreneur Li Hejun. The group began in 1989 as Yuancheng Pulisen Investment Co., Ltd., initially operating in electronic components and investment-related activities. After several corporate name changes, it adopted the Hanergy Holding Group name in 2008. Its early energy expansion centered on hydropower and wind power: it began developing the Guangdong Mujing Hydroelectric Power Station in 2000, entered wind power through the Ningxia Helanshan project in 2003, and later developed the Jiangsu Rudong Wind Farm. Although Hanergy obtained concessions for several hydropower projects in Yunnan, the Jinanqiao Hydroelectric Power Station became its principal retained hydroelectric asset. In 2009, Hanergy redirected its strategic emphasis toward thin-film photovoltaics and established a research and development center in Beijing. The group used acquisitions to assemble capabilities across several thin-film technologies. It acquired control of Hong Kong-listed Apollo Solar Energy Technology Holdings in 2010; that business was later renamed Hanergy Solar Group and then Hanergy Thin Film Power Group. In 2012, Hanergy acquired Solibro from Q-Cells and purchased MiaSolé, adding glass-based and flexible copper indium gallium selenide technology. It acquired Global Solar Energy in 2013 and Alta Devices, a gallium-arsenide photovoltaic specialist, in 2014. These transactions gave Hanergy a portfolio spanning CIGS, GaAs, and silicon heterojunction research and manufacturing capabilities. The company positioned thin-film solar as a platform for applications beyond conventional utility-scale panels. Its activities included solar parks, module and equipment manufacturing, building-integrated photovoltaics, vehicle-integrated solar, portable charging products, solar backpacks, commercial-vehicle installations, and aerospace concepts. Products and concepts associated with the group included HanTile and HanWall for solar-enabled buildings, Humbrella and HanPower portable-energy products, and HanPack solar backpacks. Hanergy also pursued original-equipment-manufacturer relationships with automotive, logistics, aviation, and consumer-product companies. The brand achieved considerable visibility through partnerships. It worked with IKEA on residential CIGS rooftop kits in several European markets, entered photovoltaic energy-management projects with FAW-Volkswagen and Guangqi Honda, and announced collaborations involving Tesla charging stations, Aston Martin Racing, Audi vehicle roofs, BAIC electric vehicles, Bolloré, Boeing, NASA, DHL, Deuter, and airport-shuttle manufacturer TAM-Europe. Other projects included solar modules for AZ Alkmaar's stadium, Mobike smart-lock and GPS systems, and solar-powered satellites known as ThinSats. Hanergy's corporate and capital-markets history has also been important to its identity. Shares of Hanergy Thin Film Power fell sharply and were suspended on the Hong Kong exchange in May 2015. Hong Kong's Securities and Futures Commission announced an investigation and ordered a continuing suspension in July of that year. Hanergy later proposed privatizing and relisting the affiliate in mainland China; the company was delisted in June 2019. Several Hanergy solar manufacturing businesses subsequently faced severe financial difficulties, including Solibro Hi-Tech, which filed for insolvency in 2020. The group nevertheless continued to present itself as a thin-film solar and mobile-energy technology business, combining renewable-power assets with technology development and application partnerships.
History
Hanergy was established in September 1989 by Li Hejun under the name Yuancheng Pulisen Investment Co., Ltd. It subsequently operated under the names Hetaihe Economic and Trade Development Co., Ltd. and Huarui Group before adopting Hanergy Holding Group in August 2008. The business initially had activities in electronic components, but gradually developed into an energy company. The group's first major energy development was the Guangdong Mujing Hydroelectric Power Station, whose development began in 2000. The project has 30 MW of installed capacity and average annual generation reported at approximately 107.66 GWh. Hanergy also obtained concessions for nine additional hydropower stations in Yunnan, although it ultimately retained control of only the Jinanqiao Hydroelectric Power Station. In 2003, the group entered wind power by constructing the Ningxia Helanshan Wind Farm, followed by the Jiangsu Rudong Wind Farm in 2006. A strategic transformation began in 2009, when Hanergy focused on thin-film solar technology and opened a Beijing research and development center. In 2010, it acquired a controlling stake in Hong Kong-listed Apollo Solar Energy Technology Holdings. Following a merger with Hanergy New Energy Research and Development, the listed business was renamed Hanergy Solar Group in 2012 and later Hanergy Thin Film Power Group. Hanergy expanded its technical portfolio through acquisitions: Solibro from Q-Cells and MiaSolé in 2012, Global Solar Energy in 2013, and Alta Devices in 2014. These businesses gave the group expertise in glass-based CIGS, flexible CIGS, and high-efficiency gallium-arsenide photovoltaics. Hanergy also established Solibro Hi-Tech GmbH and Solibro Research AB in 2015 while disposing of its shareholding in Solibro GmbH. Hanergy then pursued commercial applications for thin-film photovoltaics. In 2012 it agreed with IKEA to distribute small residential CIGS rooftop systems in the United Kingdom, later extending the arrangement to the Netherlands and Switzerland. It signed photovoltaic energy-management agreements with FAW-Volkswagen in 2013 and Guangqi Honda in 2015. During 2014, the group announced partnerships with Tesla for solar-powered charging stations, Aston Martin Racing for motorsport applications, and the Beijing ePrix as an official solar-energy partner. Further collaborations involved AZ Alkmaar, Mobike, MTbike, 99 Bicycle, BAIC BJEV, Audi, Bolloré, Boeing, NASA, DHL, Deuter, the U.S. Green Building Council, and TAM-Europe. The company experienced a major corporate crisis in 2015. On May 19, shares of Hanergy Thin Film Power fell by 47 percent and trading was suspended. On May 28, Hong Kong's Securities and Futures Commission announced an investigation, and on July 15 it ordered the suspension of all shares, preventing the company from independently resuming trading. Hanergy announced a plan in October 2018 to privatize the affiliate and seek a mainland-China relisting. Hanergy Thin Film Power was delisted in Hong Kong on June 11, 2019. Court-confirmed arrangements also required the sale of mortgaged interests in the Jinanqiao Hydroelectric Power Station, with Hanergy Mobile Energy Holding Group identified as a prospective bidder. On April 3, 2019, Li Hejun resigned as chairman and director and transferred his shares to his sisters Li Xue and Li Xia. Hanergy continued promoting thin-film applications, including HanTile and HanWall building products, Humbrella and HanPower mobile-energy products, HanPack solar backpacks, vehicle-integrated photovoltaic systems, and aerospace concepts such as ThinSats. However, parts of its manufacturing network encountered financial distress. Solibro GmbH applied for insolvency in 2019, and Solibro Hi-Tech GmbH filed for insolvency in January 2020. The group is therefore best understood as a renewable-energy and thin-film technology brand whose history combines ambitious vertical integration, cross-industry partnerships, listed-company controversy, and restructuring pressure.
