## Summary

Huasun and JA Solar represent two distinct profiles within the Chinese solar manufacturing industry. Huasun was founded in 2020 and has grown rapidly to over 2,500 employees and 20 GW of production capacity, establishing itself as the world's leading manufacturer focused exclusively on heterojunction (HJT) technology, with more than 11 GW shipped globally as of early 2025. JA Solar, by contrast, was founded in 2005 and is one of the most established names in the industry, with over 37,000 employees and a production capacity exceeding 100 GW - shipping approximately 75-79 GW of panels in 2024 alone. Both companies carry Tier 1 bankable status and are listed on the Shenzhen Stock Exchange, but their scale, age, and technology focus differ considerably.

Huasun's portfolio of 126 models is built around HJT cells (74.6% of the lineup), delivering an average module efficiency of 21.9%, an average temperature coefficient of -0.258%/°C, and a bifacial share of 89.7% - all well above industry norms. These characteristics make Huasun modules particularly well suited to space-constrained residential rooftop installations, agrivoltaic projects, and bifacial vertical installations where both low degradation under heat and strong rear-side gain matter. A 30-year average warranty further reinforces the premium positioning. JA Solar offers a far broader portfolio of 524 models led by PERC technology (52.1%), supplemented by a growing TOPCon lineup, with an average efficiency of 20.9% and a temperature coefficient averaging -0.323%/°C. Its depth of product range, global logistics network, and competitive pricing make it a natural fit for large utility-scale ground-mount projects and commercial C&I installations where volume, specification flexibility, and supply security take priority over outright efficiency leadership.

For international buyers choosing between the two, the decision hinges on project type and risk appetite. Huasun suits buyers prioritizing cutting-edge HJT efficiency and low thermal losses in premium or space-limited applications, and its rapid rise has been validated by independent bodies such as Kiwa PVEL. JA Solar suits buyers who need proven scale, a wide product selection, and the long track record that many bankability assessments and lenders prefer for large project finance structures.
