GCL Technology Holdings Limited, founded in 2006 and headquartered in Hong Kong, is listed on the Hong Kong Stock Exchange and was named among Fortune China's Top 500 companies in 2023. The company operates globally with research and development centers in locations such as the U.S., Suzhou, Xuzhou, Leshan, Baotou, Hohhot, and Zhongwei in China.

For the full year ending December 31, 2023, GCL Technology Holdings Limited reported sales of approximately $4.6 billion, a decline from the previous year’s sales of$4.9 billion. Net income also dropped significantly to $340 million USD from $2.2 billion a year ago. The company's market capitalization currently stands at $29.61 billion.

GCL Solar's product offerings include several advanced solar panel models with a focus on both monocrystalline and polycrystalline technologies. The GCL-Saturn Mono Solar Panels use monocrystalline solar cell technology, which offers higher efficiency than polycrystalline options. Monocrystalline cells are made from a single crystal structure, allowing for better performance in converting sunlight into electricity. The GCL-M8/60H panel, for example, has a rated efficiency of 21.1%, positioning it as an excellent choice for both residential and commercial installations. These panels utilize half-cut cell technology and larger solar cells to maximize energy capture, offering power outputs ranging from 355W to 390W.

On the other hand, GCL's Jupiter Polycrystalline Solar Panels offer a more cost-effective solution, though with lower efficiency compared to monocrystalline panels. Polycrystalline cells are created from multiple crystal fragments, resulting in lower production costs but reduced energy conversion efficiency. The GCL-P6/72H panel, featuring 72 cells, achieves a maximum efficiency of 18.6% with power outputs ranging from 325W to 360W. This panel is ideal for large-scale ground installations due to its lower cost and use of self-cleaning glass, which enhances performance while minimizing maintenance.

GCL Solar offers a standard 10-year product warranty across its solar panel range, ensuring coverage for any manufacturing defects. Additionally, their performance warranty guarantees 83.1% of original output after 25 years for monofacial modules and 83% after 30 years for bifacial modules, providing long-term reliability and peace of mind for customers.

14. Yingli Green Energy Holding Co. Ltd.

• Revenue: $648 million (2018)
• Net Income: -$40.5 million (2018)
• Market Cap: $1.78 million (2018)
• Exchange: New York Stock Exchange (YGE)

Yingli Green Energy Holding Company Limited is a leading solar panel manufacturer founded in 1998 by Liansheng Miao, who remains the chairman and CEO. Headquartered in Baoding, Hebei Province, Yingli Solar operates several production bases across Baoding, Tianjin, Hengshui, and other cities. Despite its significant presence in the industry, the company faced financial challenges in 2018, reporting a net loss of nearly 40.5 million U.S. dollars, with a market capitalization of 1.78 million dollars.

Yingli Solar offers a limited selection of monocrystalline solar modules, with only two of the three available models specifically designed for residential use. These include the YLM 120 half-cut cell all-black panel, offering a power rating of 315-320W and a maximum efficiency of 19.08%, and the YLM 144 half-cut cell monofacial panel, providing a higher power rating of 435-450W and a maximum efficiency of up to 20.70%. Both panels feature a positive power tolerance of 0/+5 W, ensuring that they will not fall short of their rated power and often exceed it by up to 5W.

Yingli Solar's panels come with a competitive warranty: a 12-year product warranty covering issues like broken or malfunctioning panels and a 25-year performance warranty guaranteeing that their panels will retain at least 80.70% of their original power output over 25 years.
