## Summary

AIKO is a Chinese solar manufacturer that entered commercial production relatively recently but has scaled aggressively, achieving BloombergNEF Tier 1 bankability status in Q3 2024 and reporting a nameplate production capacity of approximately 20 GW per year as of early 2025, with further expansion underway. EGing PV is also a Chinese manufacturer, founded in 2003 in Changzhou, and likewise holds Bloomberg Tier 1 status. EGing operates at a considerably smaller scale - with its single manufacturing facility reported to produce around 2 GW per year - and carries a lower profile in international markets, particularly in Western regions where it maintains a limited local support footprint. On institutional presence and production scale, AIKO has a clear advantage.

AIKO has built its identity around proprietary All Back Contact (ABC) N-type cell technology, which places all electrical contacts on the rear surface of the cell to maximize light capture. Its residential Neostar series delivers module efficiencies confirmed above 24%, while its larger-format Comet modules, targeting commercial and industrial rooftops, reach above 23.9%. This positions AIKO in the premium segment, competing against HJT rather than mainstream TOPCon. EGing PV takes a more conventional route, offering N-type TOPCon modules - including the bifacial Star Pro series - with efficiencies in the 22.3 to 22.45% range. Its product mix suits cost-sensitive commercial rooftop and small utility applications where bankability matters but maximum efficiency is not the primary criterion.

For a buyer in 2025, AIKO is the stronger choice when peak efficiency, low degradation, and a strong 30-year warranty justify a premium price - particularly for space-constrained residential rooftops. EGing PV is a reasonable alternative in markets where it has active distributor support and where standard TOPCon performance at a competitive price point is sufficient. The gap in brand recognition and global installed base is large enough that most buyers outside established EGing markets would default to AIKO or other more widely stocked options.
