## Summary

Clelo Tech is a relatively young Chinese manufacturer founded in 2017 and based in Jiangsu province, China. The company has built its entire product line around HJT (heterojunction) cell technology, maintaining a compact portfolio of just 7 panels. JA Solar, by contrast, was founded in 2005, is publicly listed on the Shenzhen Stock Exchange (SZSE), employs over 37,000 people, and operates manufacturing capacity exceeding 100 GW. JA Solar holds Tier 1 bankable status and earned a PVEL Top Performer designation for the tenth time in 2025, ranking second globally in module shipments. The two companies represent fundamentally different market profiles: Clelo Tech is a focused niche specialist with limited public track record, while JA Solar is one of the largest and most established solar manufacturers in the world.

Clelo Tech's entire lineup is 100% HJT and 100% bifacial, delivering an average module efficiency of 22.7% and a maximum of 23.2%, paired with a temperature coefficient of -0.24%/°C - among the best available for any commercial module type. This makes Clelo Tech modules well-suited to residential rooftop installations where roof space is constrained and high energy yield per square meter matters, as well as premium commercial C&I projects where thermal performance is a priority. The company offers an average product warranty of 30 years. JA Solar's 524-model portfolio spans a much broader range: approximately 52% of its catalog uses PERC cells, with the remainder including TOPCon and other advanced architectures. Its flagship modules reach 740 Wp with peak efficiency of 24.4%, though the catalog average efficiency is approximately 20.9% due to inclusion of legacy and lower-power products. JA Solar's depth of offering covers residential, commercial C&I, and large utility-scale ground-mount projects with equal capability, backed by well-established European distribution.

For buyers choosing between the two, the decision turns primarily on risk tolerance and project type. Clelo Tech suits procurement teams willing to accept a lesser-known brand in exchange for a premium all-HJT product with outstanding temperature performance and a 30-year warranty. JA Solar is the lower-risk, higher-versatility choice - its Tier 1 bankability, global service infrastructure, and portfolio breadth make it the natural default for utility-scale developers, commercial installers, and any project where long-term supply security and financier approval are non-negotiable.
