## Summary

Adani Solar is an Indian manufacturer headquartered in Mundra, Gujarat, and operates as the solar manufacturing arm of the Adani Group, one of India's largest conglomerates. The company has grown rapidly from a modest base to a current cell and module capacity of roughly 4 GW, with plans to reach 10 GW by mid-2026, according to pv-magazine. Adani Solar holds BloombergNEF Tier 1 bankability status and has earned Kiwa PVEL Top Performer recognition for seven consecutive years. Q-Cells traces its roots to Q.CELLS AG, founded in 1999 in Thalheim, Germany; South Korean conglomerate Hanwha acquired it in 2012 and merged it with Hanwha SolarOne to form Hanwha Q CELLS, now headquartered in Seoul with its R&D center remaining in Germany. With a module production capacity of approximately 12.4 GW as of late 2024 and manufacturing spread across South Korea, Malaysia, the United States, and China, Q-Cells commands a substantially larger global industrial footprint than Adani Solar at this stage.

Adani Solar's catalog centers on Mono PERC bifacial modules and, increasingly, n-type TOPCon modules under the Shine series, targeting utility-scale ground mounts and large commercial rooftops, with growing interest in the US market given the brand's UFLPA-compliant (Made in India) positioning. Q-Cells competes across a broader spectrum - its Q.PEAK DUO residential and light-commercial lines are among the most recognized names in the premium rooftop segment in Europe, Australia, and North America, while its utility-scale portfolio leverages the same TOPCon cell platform. Both companies have confirmed n-type TOPCon as their primary cell direction for the near term.

For a typical buyer outside of India in 2025, Q-Cells remains the safer default given its deeper distribution network, established after-sales infrastructure in Western markets, and longer track record in residential deployments. Adani Solar is compelling for Indian utility projects or for international buyers specifically seeking non-Chinese supply chains, and its bankability credentials are strong enough that it should not be dismissed as a second-tier option.
