## Summary

JA Solar, founded in 2005 and headquartered in China, is one of the largest solar module manufacturers in the world, with over 37,000 employees and a production capacity exceeding 100 GW per year. The company ranked third globally in 2024 with shipments of approximately 79.5 GW - a 40% year-on-year increase - and has received "Top Performer" status from PVEL for the tenth consecutive time in 2025, underscoring its reliability credentials. It is listed on the Shenzhen Stock Exchange and holds Tier 1 bankable status. New East Solar Energy is a significantly smaller manufacturer based in Cambodia, with 201 to 500 employees and a production capacity in the 5-10 GW range. Despite its more modest scale, the company also holds Tier 1 bankable status and has been expanding its footprint, including announced plans for a 2 GW manufacturing facility in Phoenix, Arizona, with additional offices in Los Angeles targeting the North American market.

JA Solar's portfolio of 524 panel models is dominated by PERC technology (over 52% of the range), with a maximum panel power of 740 Wp, a maximum efficiency of 24.4%, and an average efficiency of 20.87%. Its breadth of product SKUs makes it well suited for large utility-scale ground-mount projects, commercial and industrial (C&I) installations, and residential rooftop systems where installer flexibility and supply chain reliability are paramount. New East Solar's narrower range of 30 models leans heavily toward the more modern TOPCon n-type cell technology (approximately 67% of its portfolio), delivering a higher average efficiency of 21.79% and a higher average panel power of 535 Wp, with two-thirds of models being bifacial - making it a compelling option for ground-mount installations and projects where maximizing yield per module is a priority.

For international buyers comparing the two, JA Solar offers unmatched scale, a long track record, extensive European service infrastructure, and a diversified product range that reduces procurement risk on large projects. New East Solar presents an attractive proposition for buyers seeking a higher-efficiency, TOPCon-focused portfolio from a Tier 1-rated manufacturer, though its shorter European market history and smaller organizational footprint are factors worth weighing carefully in long-term project planning.
