## Summary

Q-Cells, operating as Hanwha Q CELLS, is a South Korean manufacturer founded in 1999 and now a division of the Hanwha Group conglomerate. It holds confirmed Bloomberg NEF Tier 1 bankability status and operates at a global module production capacity of roughly 11.2 GW annually, with US-based module capacity across two Georgia facilities reaching approximately 8.4 GW - making it one of the few manufacturers with a fully integrated solar supply chain on Western soil. SP Enerji is a Turkish manufacturer headquartered in the Haci Sabanci Organized Industrial Zone in Adana. It was established to serve the domestic and regional market for mono- and polycrystalline panels, and its publicly reported annual production capacity is approximately 66 MWp - several orders of magnitude smaller than Q-Cells. No evidence of a Bloomberg NEF Tier 1 designation for SP Enerji was found. On institutional footprint, Q-Cells is the significantly stronger of the two.

Q-Cells serves the full spectrum of applications, from premium residential rooftops to utility-scale ground mounts. Its core technology lines are Q.ANTUM (PERC-based) and Q.ANTUM NEO, the latter being its branded TOPCon implementation under the Q.TRON product family, which achieves module efficiencies up to approximately 22.6%. The company is actively transitioning its Georgian factories to TOPCon-only output. SP Enerji's publicly listed catalog centers on PERC modules in the 320 W to 395 W range, with efficiencies between roughly 16.5% and 19.89%, positioned for budget-oriented commercial and residential installations primarily in Turkey and neighboring markets. No TOPCon or HJT product lines were confirmed for SP Enerji through available sources.

For most buyers outside Turkey - particularly those seeking bankable, warrantied panels for residential or commercial projects - Q-Cells is the substantially safer default in 2025, backed by verified Tier 1 status, broad installer networks, and long-term product warranties of up to 25-30 years. SP Enerji may be a viable lower-cost regional option for Turkish-market projects where local supply chains and pricing matter most, but buyers should verify warranty support independently.
