## Summary

JA Solar, founded in China in 2005, ranks among the world's largest solar panel manufacturers, with a production capacity exceeding 100 GW and a workforce of over 37,000 employees. The company holds Tier 1 bankable status and is listed on the Shenzhen Stock Exchange (SZSE), giving it strong credibility with institutional investors and project finance lenders globally. With a catalogue of 524 panel models, JA Solar has built a commanding position across both established and emerging markets, consistently earning recognition in independent reliability assessments such as the PVEL Scorecard. Recom, founded in Italy in 2007, operates at a considerably smaller scale with 61 panel models and does not hold Tier 1 bankable status. Despite its more limited market footprint, Recom has established itself as a quality-oriented European manufacturer with a distribution reach spanning over 110 countries, positioning itself as a premium alternative to large Asian producers.

JA Solar's portfolio is predominantly built on PERC cell technology, which accounts for over 52% of its models, though the company is actively extending its TOPCon-based lineup through the DeepBlue 4.0 Pro and 5.0 series. Its average panel efficiency of 20.87% reflects the breadth of its catalogue, which spans entry-level and high-performance modules alike, with a peak efficiency of 24.4%. Its scale, Tier 1 status, and supply chain depth make it particularly well-suited for utility-scale ground-mount projects and bank-financed commercial C&I installations where supplier bankability is a contractual requirement. Recom, by contrast, has committed heavily to TOPCon technology, which represents over 83% of its portfolio, yielding a meaningfully higher average module efficiency of 22.68% and an average module power of 547 Wp - well above JA Solar's 442 Wp average. A better average temperature coefficient of -0.284%/°C compared to JA Solar's -0.323%/°C, combined with a standard 30-year product warranty, makes Recom panels a strong choice for space-constrained residential rooftop installs and premium commercial C&I projects where output per square metre and long-term warranty coverage are primary selection criteria.

For international buyers choosing between the two, the decision comes down to scale, financing requirements, and technology priorities. JA Solar is the lower-risk, bank-friendly option for large-scale projects, backed by an unmatched manufacturing footprint and a proven global track record. Recom offers a technologically more cohesive and advanced portfolio centered on TOPCon, with superior average efficiency and temperature performance, appealing to buyers who prioritize high yield and European supply chain proximity over sheer manufacturing scale. Buyers without strict bankability constraints who value efficiency leadership and a full 30-year warranty may find Recom's proposition compelling despite its smaller market presence.
