Hanergy Holding Group: A Legacy of Thin-Film Solar Innovation and Energy Diversification
Founded in 1989, Hanergy Holding Group has evolved from a small electronic components business into a global powerhouse in the renewable energy sector. Headquartered in the Chaoyang District of Beijing, the company has spent decades diversifying its portfolio across hydroelectric, wind, and most notably, thin-film photovoltaic (PV) technologies. With a workforce exceeding 15,000 employees, Hanergy has sought to integrate solar power into every facet of modern life, from urban architecture to aerospace.
The company's journey is marked by aggressive expansion and a commitment to thin-film solar—a technology that allows solar cells to be flexible, lightweight, and integrated into surfaces where traditional silicon panels would be impractical.

Corporate Evolution and History
Hanergy began as Yuancheng Pulisen Investment Co., Ltd. in September 1989, later transitioning through names such as Hetaihe Economic and Trade Development Co., Ltd. and Huarui Group before becoming Hanergy Holding Group in 2008. Its early growth was rooted in traditional renewables; by 2000, it developed the Guangdong Mujing Hydroelectric Power Station (30 MW) and later expanded into wind energy with the Ningxia Helanshan and Jiangsu Rudong wind farms.
The Pivot to Thin-Film Solar
In 2009, Hanergy shifted its strategic focus toward the thin-film solar industry, establishing a dedicated R&D center in Beijing. To accelerate its technological capabilities, the company embarked on a series of high-profile acquisitions:
- Apollo Solar Energy Technology: Acquired in 2010, eventually becoming Hanergy Thin Film Power Group, Ltd.
- Solibro and MiaSolé: Acquired in 2012 to enhance CIGS (Copper Indium Gallium Selenide) thin-film module production.
- Global Solar Energy: Acquired in 2013 for further CIGS PV expertise.
- Alta Devices: Acquired in 2014, bringing world-leading Gallium Arsenide (GaAs) technology into the fold.

Strategic Partnerships and Applications
Hanergy's business model focused on integrating solar technology into consumer products and industrial infrastructure. The company collaborated with several global brands to showcase the versatility of thin-film PV.
Automotive and Transport
Hanergy partnered with Tesla to power charging stations in Beijing and Shanghai, and worked with Audi to integrate solar cells into panoramic glass roofs to extend electric vehicle range. Other notable collaborations included Aston Martin Racing for the FIA World Endurance Championship and Bolloré for the development of solar electric vehicles. In the logistics sector, they partnered with DHL for commercial vehicle rooftops and TAM-Europe for solar-powered airport shuttle buses.
Consumer Goods and Urban Integration
The company expanded into the consumer market through a partnership with IKEA to sell residential solar kits in the UK, Netherlands, and Switzerland (ended in 2015). They also collaborated with bike-sharing firms like Mobike, MTbike, and 99 Bicycle to power smart locks and GPS systems via solar modules.
Aerospace and Science
Pushing the boundaries of the technology, Hanergy worked with Boeing on the "Perpetual Aircraft" unmanned aerial vehicle and provided 60 "ThinSats" (solar-powered satellites) to NASA for atmospheric analysis during the NG-11 mission.
Product Ecosystem
Hanergy's product line is divided between building-integrated photovoltaics (BIPV) and mobile energy solutions.
Green Building Solutions
- HanTile: Solar roof tiles available in double-glass (Triple-Arch and Spool series) and a newer, thinner single-glass generation.
- HanWall: A BIPV solution designed for integrating solar power directly into building walls.
Mobile Energy Products
- Humbrella: A solar-equipped umbrella featuring batteries ranging from 9,600 mAh to 25,200 mAh.
- HanPack: Solar-powered backpacks with CIGS modules providing between 6.14 W and 9 W.
- HanPower Plus-In: A portable charger combining a 12 W thin-film module with a magnetic storage interface.

Corporate Challenges and Restructuring
Despite its technological leaps, Hanergy faced significant financial and regulatory turmoil. In May 2015, shares of Hanergy Thin Film Power crashed by 47%, leading to a suspension on the Hong Kong Exchange and an investigation by the Securities and Futures Commission. The company was eventually delisted from the Hong Kong stock exchange on June 11, 2019, following a plan to privatize and relist on the Chinese mainland.
Additionally, some subsidiaries faced insolvency, including Solibro GmbH in 2019 and Solibro Hi-Tech GmbH in 2020. Alta Devices was also closed in 2019.

Frequently Asked Questions
What is CIGS technology used by Hanergy?
CIGS stands for Copper Indium Gallium Selenide. It is a type of thin-film solar cell that is more flexible and lightweight than traditional crystalline silicon, allowing it to be integrated into curved surfaces like roofs, walls, and consumer electronics.
What was the significance of the Alta Devices acquisition?
The acquisition of Alta Devices gave Hanergy access to Gallium Arsenide (GaAs) technology, which held world records for solar cell conversion efficiency, reaching 29.1% for single-junction and 31.6% for dual-junction cells.
Why was Hanergy Thin Film Power delisted from the Hong Kong Exchange?
The company faced a severe stock crash in 2015, followed by an investigation by the Securities and Futures Commission. After a long suspension, the company pursued privatization and was delisted in June 2019.
How did Hanergy contribute to aerospace technology?
Hanergy provided thin-film solar modules for Boeing's "Perpetual Aircraft" UAV and supplied 60 solar-powered satellites (ThinSats) to NASA for the NG-11 atmospheric research mission.
What are HanTile and HanWall?
HanTile consists of solar-powered roof tiles that replace traditional roofing materials, while HanWall is a system designed to integrate photovoltaic power generation directly into the exterior walls of buildings.
