Qcells has been crowned the top solar panel brand for the second year in a row by SolarReviews, establishing itself as a premier choice for both residential and commercial solar installations. Founded in 1999 in Germany and later acquired by South Korea's Hanwha Group, the company combines decades of solar innovation with world-class manufacturing capabilities. Qcells now operates the largest solar manufacturing plant in the Western Hemisphere in Dalton, Georgia, and currently makes more solar panels in North America than any other manufacturer.
The fusion of German engineering precision with Korean manufacturing expertise has created a solar technology powerhouse that continues to push industry boundaries. In December 2024, Hanwha Qcells achieved 28.6% efficiency on an M10-sized perovskite-silicon tandem cell, as independently verified by the CalLab at the Fraunhofer Institute, demonstrating their commitment to next-generation solar technology.
Q Cells has a unique heritage as a German company that was acquired by the Korean Hanwha Group in 2012, combining German engineering with Korean manufacturing expertise to create cutting-edge solar solutions. This international collaboration has resulted in proprietary technologies that set Qcells apart in the competitive solar market.
Their proprietary Q.ANTUM and Q.ANTUM DUO technologies are significant innovations based on PERC (Passivated Emitter Rear Cell) technology, improving efficiency, low-light performance, and temperature tolerance while reducing issues like Potential Induced Degradation (PID). This advanced technology ensures Hanwha Q CELLS solar panels deliver consistent performance even in challenging environmental conditions.
Manufacturing Excellence
Hanwha Qcells' total annual U.S.-based module production capacity reached 8.4 gigawatts (GW) with facilities in Georgia. Any Qcells panel you buy in America will likely have been made by workers in Georgia, ensuring quality control and supporting domestic manufacturing.
Quality Assurance
Q CELLS holds Bloomberg's Tier 1 ranking—a testament to its financial stability and strong market presence. With Tra.Q, Q Cells can conduct extensive testing on each panel and trace any issues back to specific manufacturing batches, ensuring higher reliability and fewer defects.
Performance Standards
Qcells panels have efficiency ratings up to 22.5%, with 20%-22.5% conversion rate puts Q CELLS above many other manufacturers, with panels retaining from over 85% to over 90% of their power after 25 years.
Warranty Protection
The company offers 12 or 25-year product warranties and 25 or 30-year performance warranties, backed by Hanwha's financial stability for long-term peace of mind.
