## Summary

AE Solar is a German solar module manufacturer founded in 2003 and headquartered in Königsbrunn, Bavaria, with production facilities in China, Georgia, and Turkey and a combined annual manufacturing capacity of approximately 2.5 GW. The company has been listed on BloombergNEF's Tier 1 PV Module Manufacturer ranking for the 16th consecutive time as of Q1 2025, and BloombergNEF specifically recognized AE Solar as Europe's sole Tier 1 module maker with high bankability in 2024 - a distinction that carries significant weight with project finance lenders and institutional procurement teams. Q-SUN Solar is a Chinese manufacturer established in 2014 and headquartered in Nanjing, Jiangsu, with production sites in Tianchang and Yancheng and a stated annual output above 4 GW. No BloombergNEF Tier 1 listing for Q-SUN Solar was found during research, which is a material consideration for buyers who need bankable modules for non-recourse project finance. On institutional footprint, AE Solar holds the clearly stronger position.

AE Solar's 2025 lineup spans N-type TOPCon panels in the Meteor series (415 W to 725 W), high-efficiency HJT modules in the Comet series reaching up to 23.05% module efficiency, and the Aurora range in monofacial and bifacial formats suited to residential rooftop, commercial C&I, and utility-scale ground-mount projects alike. Q-SUN Solar covers similar ground: the Mercury series brings N-type TOPCon technology across a 400 W to 720 W power range at efficiency above 22.5%, while the Onyx full-black series (440-460 W, up to 23.0% efficiency) targets aesthetics-driven residential buyers. The company also offers an HJT product in the Qrystal N8 line and backs its modules with a 30-year linear power warranty - notably longer than the prevailing 25-year industry standard.

For most buyers, both manufacturers offer technically comparable N-type TOPCon products at similar efficiency levels, and for smaller residential installations the two are broadly interchangeable. AE Solar is the safer default whenever bankability documentation, EU supply-chain traceability, or institutional due diligence is required - factors that matter most in large commercial, C&I, and utility projects across European markets. Q-SUN Solar may appeal to price-sensitive buyers in segments where Tier 1 certification is not a hard requirement, particularly given its longer warranty terms and competitive product specifications.
