## Summary

Jinko Solar, founded in 2006 and headquartered in China, is listed on the NYSE and ranks among the world's leading solar module manufacturers with a declared production capacity of 130 GW and a workforce of over 33,800 employees. The company holds Tier 1 bankable status and offers a portfolio of 545 panel models, reflecting a vast product range suited to virtually any project type and scale. Suntech, founded earlier in 2001 and also based in China, is a smaller but well-established Tier 1 manufacturer with a portfolio of 136 models. Both companies share the same geographic origin and serve global markets, but Jinko Solar's considerably larger production scale and NYSE listing give it a stronger footprint in terms of supply chain reliability and institutional investor confidence.

On the technology side, both manufacturers have adopted TOPCon as their leading cell platform, though the depth of commitment differs. Jinko Solar's TOPCon share stands at 39.4% of its portfolio, with maximum module power reaching 735 Wp, average power of 511 Wp, maximum module efficiency of 24.8%, and an average efficiency of 22.0%. Suntech has committed 100% of its current portfolio to TOPCon, achieving maximum module power of 720 Wp, average power of 516 Wp, and maximum efficiency of 23.2%. Suntech's bifacial ratio is notably higher at 42.6% compared to Jinko's 31.9%, making it a compelling option for ground-mount installations and bifacial-optimized commercial projects. Average warranty lengths are comparable - 29.1 years for Suntech and 28.5 years for Jinko - and both share a virtually identical average temperature coefficient of approximately -0.308 %/°C.

For utility-scale developers and commercial C&I buyers, Jinko Solar's unmatched production scale, broad product range, and global supply chain depth make it a low-risk, highly bankable choice. For residential rooftop installs or mid-size projects where a fully standardized all-TOPCon portfolio with a higher proportion of bifacial modules is preferred, Suntech presents a focused and technically coherent offering. International buyers selecting between the two should weigh Jinko's scale and global brand recognition against Suntech's tighter product focus, higher bifacial share, and slightly higher average module output.
