## Summary

Jetion Solar is a Chinese manufacturer founded in 2004 and headquartered in Jiangyin, Jiangsu Province. Since 2014 it has operated as a subsidiary of China National Building Materials Group (CNBM), a state-backed conglomerate. Jetion re-entered the BloombergNEF Tier 1 PV Module Maker list in Q2 2024 and is one of the few heterojunction-focused producers to hold that designation. The company reports module capacity of roughly 2.5 GW and cell capacity of around 4.4 GW across plants in China and Thailand, with cumulative shipments exceeding 20 GW in more than 60 countries. Q-Cells traces its roots to Germany, where it was founded in 1999; South Korea's Hanwha Group acquired it in 2012, and it now operates as Hanwha Q CELLS. The combined entity is a long-standing Tier 1 BloombergNEF name with a multi-continent manufacturing footprint that includes South Korea, a large and expanding facility in Cartersville, Georgia, and European operations. On sheer production scale and institutional depth, Hanwha Q CELLS carries the stronger footprint.

On the product side, Jetion has staked its differentiation on heterojunction (HJT) cell technology, which offers low temperature coefficients and strong bifacial performance, positioning its panels for buyers where efficiency density and low-light yield are priorities across residential and utility segments. Q-Cells is best known for its proprietary Q.ANTUM technology - a PERC-based architecture enhanced with selective passivation improvements - and has been expanding into TOPCon and, at pilot scale, perovskite-silicon tandem development. Q.ANTUM panels cover a broad range from residential rooftop to mid-scale commercial, and the brand maintains well-established installer networks in Europe, Australia, and North America.

For a typical buyer in 2025, Hanwha Q CELLS is the lower-risk default: its warranty infrastructure, installer familiarity, and multi-decade track record reduce procurement friction considerably. Jetion is a credible alternative for buyers specifically targeting HJT performance and comfortable working with a more technology-focused, mid-scale supplier.
