## Summary

JA Solar and Rarlon PV Tech are both Chinese solar panel manufacturers, but they occupy vastly different positions in the global PV industry. JA Solar was founded in 2005, is publicly listed on the Shenzhen Stock Exchange (SZSE), employs over 37,000 people, and operates with a production capacity exceeding 100 GW per year. The company holds Tier 1 bankable status recognized by S&P Global Commodity Insights and BloombergNEF, and jointly topped Wood Mackenzie's Global Solar Module Manufacturer Ranking for H1 2025 alongside Trinasolar. Rarlon PV Tech, headquartered in Ningbo, is a substantially smaller manufacturer with no publicly disclosed production capacity, no Tier 1 classification, and a comparatively limited market presence - primarily exporting to Europe, South America, the Middle East, Africa, and Southeast Asia.

JA Solar's portfolio spans 524 panel models, with a maximum output of 740 Wp, a maximum efficiency of 24.4%, an average portfolio efficiency of 20.87%, and an average temperature coefficient of Pmax at -0.32%/°C. Over 44% of its portfolio consists of bifacial modules, and the average product warranty stands at nearly 28 years. The company's newer Deep Blue 4.0 series employs TOPCon cell technology, while PERC remains the dominant technology across its broader catalogue. JA Solar is well-suited to utility-scale ground-mount projects, commercial and industrial (C&I) installations requiring bankable financing, and high-efficiency residential rooftop systems. Rarlon PV Tech offers 52 panel models with a maximum output of 550 Wp, a maximum efficiency of 21.5%, an average efficiency of 18.33%, and an average temperature coefficient of -0.44%/°C - notably weaker heat performance. The company offers no bifacial panels and provides a 25-year average warranty. Its portfolio is predominantly PERC-based and best suited to budget-driven residential or small commercial projects where upfront cost takes priority over peak performance.

For international buyers evaluating the two, JA Solar is the clear choice for any project where bankability, long-term reliability, high efficiency, or bifacial yield are required - including utility-scale, C&I, and quality-focused residential installations. Rarlon PV Tech may be a viable consideration for cost-sensitive projects in price-competitive markets, off-grid applications, or auxiliary system components, but it cannot match JA Solar's track record, product depth, or independent performance validation.
