## Summary

JA Solar and Ruihuang New Energy and Science are both China-based solar module manufacturers, but they occupy entirely different tiers of the global market. JA Solar was founded in 2005, employs over 37,000 people, and operates a production capacity exceeding 100 GW, placing it among the largest module manufacturers in the world. The company holds Tier 1 bankable status from BloombergNEF and S&P Global Commodity Insights, is publicly listed on the Shenzhen Stock Exchange (SZSE), and has achieved cumulative global module shipments approaching 300 GW. Wood Mackenzie ranked JA Solar jointly first among global module manufacturers for H1 2025. Ruihuang New Energy and Science (brand name RHSOLAR), by contrast, was founded in 2018, employs between 100 and 200 people, and declares a production capacity in the 1-3 GW range. The company does not appear on any Tier 1 bankability list and is not publicly traded.

JA Solar's portfolio spans 524 panel models, anchored by the Deep Blue 4.0 TOPCon series reaching up to 23% efficiency and the Deep Blue 3.0 PERC series. Maximum rated output reaches 740 Wp, average panel efficiency sits at approximately 20.9%, and the average temperature coefficient of Pmax is -0.32%/°C, indicating solid performance in warmer climates. Average warranty coverage across the portfolio exceeds 27 years, and PVEL awarded JA Solar Top Performer status for the tenth consecutive time in its 2025 reliability scorecard. This breadth makes JA Solar suitable for residential rooftop installs requiring compact, high-efficiency modules, commercial C&I projects leveraging the bifacial range (over 44% of the portfolio), and utility-scale ground-mount projects where bankability and supply chain stability are critical. Ruihuang lists a power range of 50-710 Wp and claims coverage of PERC, Bifacial, TOPCon, and N-type technologies, but independent performance data, third-party certifications, and verifiable shipment records are not publicly available.

For international buyers - whether project developers, EPCs, or distributors - JA Solar offers a well-documented track record, global service infrastructure, and the financial bankability required for project debt financing. Ruihuang may be of interest to cost-focused importers willing to conduct their own factory audits and quality verification, but carries substantially higher procurement risk for any project requiring lender approval or long-term performance guarantees.
