## Summary

AIKO Solar is a Chinese manufacturer headquartered in Guangzhou, founded in 2009, that has grown rapidly on the back of its proprietary ABC (All Back Contact) N-type cell technology. The company achieved BloombergNEF Tier 1 bankability status in 2024 and has reported a production capacity of approximately 20 GW for its ABC lines. Q-Cells, operating under South Korean conglomerate Hanwha since 2012, traces its origins to Q-Cells AG, a German firm founded in 1999, and today produces panels across South Korea, Germany, Malaysia, and the United States. Q-Cells holds long-standing BloombergNEF Tier 1 status and runs approximately 8.4 GW of capacity in Dalton, Georgia alone - the largest solar manufacturing plant in the Western Hemisphere. In terms of established institutional footprint, Q-Cells commands the wider global reach and the longer bankability track record.

Q-Cells offers two main technology lines: the Q.PEAK DUO series based on its Q.ANTUM DUO PERC architecture for cost-sensitive residential and commercial rooftops, and the newer Q.TRON line using TOPCon cells for higher-efficiency applications. AIKO's lineup is unified around ABC technology, with Gen 3 modules achieving confirmed module efficiencies above 24%, a notably low temperature coefficient, and strong shade tolerance thanks to rear-contact cell design. Independent installer surveys ranked AIKO first in the 2025 SolarQuotes Installers' Choice Awards, reflecting growing professional confidence in the platform.

For a typical residential buyer in 2025, Q-Cells is the lower-risk default - its multi-decade warranty infrastructure, U.S. domestic manufacturing that qualifies for IRA incentives, and deep installer network are difficult to match. AIKO is the stronger pick where roof space is constrained and peak efficiency is the decisive criterion, though buyers should note that its Tier 1 designation is recent and its global service network is still maturing. The two brands occupy overlapping but distinct niches rather than being straightforwardly interchangeable.
