## Summary

AKCOME was founded in 2003 in China and operates as a specialist heterojunction (HJT) module manufacturer with a deliberately narrow product range. Unlike high-volume Chinese producers, AKCOME does not hold Tier 1 bankable status under BloombergNEF classification, positioning it as a premium technology provider rather than a mainstream volume supplier. The three models represented in this dataset reach up to 700 Wp with an average efficiency of 21.63% and an average warranty of 30 years - all panels are bifacial. JA Solar, founded in 2005 and listed on the Shenzhen Stock Exchange, occupies a fundamentally different position in the global market. The company operates over 100 GW of production capacity, employs more than 37,000 people, and holds an AAA bankability rating from PV ModuleTech. In the first half of 2025, JA Solar jointly ranked first globally in Wood Mackenzie's module manufacturer ranking. Its 524-model portfolio spans mainstream residential panels to high-power utility modules reaching 740 Wp and a peak efficiency of 24.4%, with PERC technology accounting for 52% of its lineup alongside a growing TOPCon offering.

AKCOME's primary advantage is its exclusive focus on HJT cells, which deliver an exceptionally low temperature coefficient of -0.24%/°C for Pmax - significantly better than JA Solar's portfolio average of -0.32%/°C. Combined with 100% bifacial design and a 30-year average warranty, AKCOME modules are well-suited for premium residential rooftop installations and commercial C&I projects where long-term yield and hot-climate performance justify a price premium. JA Solar's strength lies in scale, supply reliability, and versatility. Its broad portfolio covers residential rooftop installs, utility-scale ground-mount farms, and commercial C&I projects across Europe, Asia, and the Americas. The 44% bifacial share within its lineup provides competitive options for tracker-based utility projects, and its AAA bankability rating simplifies project finance with institutional lenders.

For international buyers seeking a reliable, financeable, and globally supported module supplier, JA Solar is the lower-risk choice regardless of project scale. AKCOME is a compelling option for buyers willing to work with a non-Tier-1 supplier in exchange for best-in-class HJT temperature performance and extended warranty terms - particularly attractive for premium residential and C&I installations where long-term energy yield takes priority over upfront cost.
