## Summary

Panasonic is a Japanese electronics conglomerate founded in 1918 and headquartered in Osaka, which spent decades building a reputation in solar around its heterojunction (HJT) EverVolt panels - praised for efficiency ratings above 22% and a low temperature coefficient. Crucially, however, Panasonic announced on April 28, 2025 that it was exiting the solar and battery storage business entirely, ending all new panel production and sales. It had already transferred manufacturing to OEM partner REC Group in 2021, and its residential installation share had slid from roughly 35% in 2020 to around 6% by 2024, according to reporting by pv-magazine and CleanTechnica. Existing warranty obligations are being honored, but Panasonic panels are no longer available for new projects. Q-Cells - formally Hanwha Q CELLS - traces its roots to a German company founded in 1999 and acquired by South Korea's Hanwha Group in 2012. It holds a consistent BloombergNEF Tier 1 bankability rating and was named an S&P Global 2025 Tier 1 Cleantech company. The company operates manufacturing at significant scale, with facilities in Cartersville, Georgia anchoring a combined US capacity reportedly above 8 GW, giving it strong domestic-content credentials under the Inflation Reduction Act. Q-Cells carries the stronger active institutional footprint of the two.

Q-Cells built its product identity around Q.ANTUM, a proprietary PERC-based cell platform incorporating Anti-LeTID, Anti-PID, and Hot-Spot Protect features to reduce real-world degradation. Its current flagship residential series, the Q.TRON G2, uses the Q.ANTUM NEO platform with TOPCon cell architecture and pushes efficiencies above 22%, closing the gap that once separated its PERC modules from HJT competitors. The portfolio spans residential rooftop, commercial flat-roof, and utility-scale applications at mid-market pricing, and SolarReviews ranked Q-Cells among the top three solar panel manufacturers for 2025.

For any buyer planning a new installation today, the comparison is effectively settled by Panasonic's market exit. Panasonic's EverVolt technology was genuinely competitive - arguably best-in-class on temperature performance and warranty depth - but no new units are available and no manufacturing roadmap exists. Q-Cells is the active, bankable, and widely distributed choice, particularly well-positioned in North America given its domestic manufacturing footprint and continued product development.
