## Summary

Q-Cells, now operating as Hanwha Q CELLS under South Korea's Hanwha Group following its 2012 acquisition of the original German Q-Cells GmbH, is one of the most recognized panel brands in Western markets and holds Bloomberg Tier 1 bankability status. The company has established an 8.4 GW module production footprint in the United States alone, with total module shipments projected to exceed 9 GW in 2025, making it among the largest solar manufacturers active in North America. SolarReviews ranked Q CELLS third among all panel brands in its 2025 assessment. TommaTech, by contrast, is a smaller German-registered company (TommaTech GmbH) that designs panels to German engineering standards and manufactures through its Turkish partner CW Enerji, which carries an annual production capacity of around 1.3 GW. No Bloomberg Tier 1 listing for TommaTech was found in available sources. In terms of institutional footprint and bankability assurance, Q CELLS holds the significantly stronger position.

Q CELLS panels span the premium-to-mid-market residential and commercial segments, with independently confirmed module efficiencies between 20% and 22.5%, product warranties of up to 25 years, and performance guarantees of up to 30 years. The company produces PERC-based panels and has been actively investing in TOPCon and perovskite cell technology. TommaTech concentrates on monocrystalline PERC modules - including half-cut multi-busbar designs reaching up to 675 Wp - and also offers niche formats such as flexible panels for marine and vehicle applications and BIPV modules. Its standard warranty stands at 15 years for the product and 30 years for performance.

For a typical buyer in 2025, Q CELLS is the safer default: its Tier 1 bankability, large-scale production base, growing North American manufacturing presence, and broad installer network lower both project-finance risk and long-term warranty risk. TommaTech can be a reasonable choice for buyers in Turkey or Central Europe seeking European-quality-standard PERC panels or specialized flexible formats, but it lacks the independent verification and global service coverage that Q CELLS offers.
