Sunman vs AKCOME - solar panel manufacturer comparison

Sunman is a Chinese solar manufacturer founded in 2014 and headquartered in Shanghai, led by Dr. Zhengrong Shi, the scientist widely credited with helping establish China's photovoltaic industry. The company opened a 1 GW lightweight module factory in Jiangsu province in 2022 and has shipped over 600 MW of its eArc modules to more than 40 countries. Sunman does not appear on BloombergNEF's Tier 1 list, positioning it as a specialty niche player rather than a mainstream bankable supplier. AKCOME - full name Suzhou Akcome Optronics Science and Technology Co., Ltd. - was founded in 2006 and is listed on the Shenzhen Stock Exchange, with manufacturing bases across four Chinese cities and offices in Germany, Japan, South Korea, and Australia. AKCOME has announced plans to scale its HJT cell capacity to over 8 GW, and its larger institutional footprint and stock-market listing give it a stronger bankability profile for project finance purposes.

The two manufacturers serve quite different product segments. Sunman's flagship eArc line is a glass-free, polymer-composite panel that is roughly 70 percent lighter than a conventional glass module, can be bonded directly to curved or structurally limited surfaces, and targets commercial and industrial rooftops unable to bear normal panel weight, as well as BIPV, marine, vehicle, and carport applications. Efficiency tops out at around 19.3 percent on its 520 W model, a trade-off accepted in exchange for form factor flexibility. AKCOME, by contrast, focuses exclusively on high-efficiency crystalline silicon - specifically HJT technology confirmed across its portfolio - with module efficiencies reported up to 22.5 percent, bifacial dual-glass construction, and power classes in the 655 W to 700 W range suited to utility-scale ground mounts and mainstream commercial rooftops.

For a buyer weighing a conventional ground-mount or rooftop project in 2025, AKCOME's HJT lineup is the more straightforward choice, offering competitive efficiency and a wider installer network. Sunman is the more compelling option - and often the only practical one - where roof loading constraints rule out glass panels or where curved and unconventional mounting surfaces are involved. The two brands are not really interchangeable; they solve different engineering problems.
