## Summary

AIKO is a Chinese solar manufacturer headquartered in Ningbo, founded in 2009, that has built its market identity around proprietary ABC (All Back Contact) cell technology. The company achieved BloombergNEF Tier 1 status in 2024 and is aggressively scaling production, with a new facility in Jinan targeting 30 GW of cell and module capacity alongside existing plants, making AIKO one of the faster-growing names in high-efficiency manufacturing. DMEGC - part of the diversified Hengdian Group based in Zhejiang province - brings more than four decades of industrial history to photovoltaics. The company holds confirmed BloombergNEF Tier 1 status reaffirmed in Q3 2025, earned an "A" rating in the PV ModuleTech Bankability Report, and operates module production capacity of approximately 21 GW per year, with cumulative global shipments exceeding 50 GW. On the combined measure of institutional longevity, financial depth, and established bankability, DMEGC carries the stronger track record.

AIKO's product lineup centers on ABC modules that eliminate front-side busbars and achieve module efficiencies exceeding 25% in the latest commercial generation - a world-leading figure for mass-produced panels. Independent testing confirms ABC modules deliver up to 30 W more per panel than comparable TOPCon products, a superior temperature coefficient of -0.26%/degrees C, and meaningfully better partial-shading performance, making them particularly compelling for space-constrained residential rooftops and commercial C&I installations where every square meter counts. AIKO won the SolarQuotes Installers Choice Award for best solar panels in 2025, reflecting strong real-world installer sentiment. DMEGC covers the full market spectrum with N-type TOPCon modules ranging from lightweight bifacial double-glass panels designed for single-family homes to the large-format Infinity RT series reaching up to 720 Wp and 24.6% efficiency for utility-scale ground-mount and large industrial rooftop projects. DMEGC also offers agri-PV configurations and customized framing solutions, and appears as a Top Performer in the Kiwa PVEL PV Module Reliability Scorecard.

For most international buyers - especially those working with project finance lenders who weight Tier 1 bankability heavily - DMEGC is the lower-risk default, backed by decades of financial stability and a broad, reliability-tested product range. AIKO is the standout pick when watts-per-square-meter is the primary constraint and the buyer is willing to pay a technology premium for ABC. Both are credible manufacturers rather than interchangeable commodities, and the decision ultimately comes down to whether efficiency leadership or institutional depth is more critical to the specific project.
