Written summary
AIKO is a Chinese solar manufacturer headquartered in Shanghai, founded in 2009 and now one of the industry's most-watched technology leaders. It achieved BloombergNEF Tier 1 bankability status in Q3 2024, and by Q2 2026 its listed annual production capacity was approximately 35.5 GW, placing it firmly in the top tier of global module suppliers. Zun Power, by contrast, is a much smaller Canadian manufacturer based in Montreal, Quebec, operating under the GMA Solar brand and noted as the only solar PV module producer in the province. It holds CSA and TUV Rheinland certifications but does not appear on any BloombergNEF Tier 1 list. On institutional footprint - global financing access, bankability ratings, and production scale - AIKO is the considerably stronger name.
The two companies also diverge sharply on product positioning. AIKO's defining technology is its proprietary ABC (All Back Contact) cell architecture, which is distinct from mainstream TOPCon or HJT designs. By eliminating front-side shading wires, AIKO's Neostar series has reached module efficiencies above 25%, among the highest commercially available, with a low temperature coefficient that delivers above-average yield in hot climates. The product line is aimed squarely at premium residential rooftops and space-constrained commercial installations where every watt per square metre counts. Zun Power offers a broader, more conventional range spanning PERC, TOPCon, and bifacial modules from small off-grid panels up to 670 W modules, targeting commercial, agricultural, institutional, and industrial projects primarily within Canada.
For buyers outside Canada, AIKO is the more defensible choice in 2025 given its Tier 1 bankability, scale, and class-leading ABC efficiency figures. Zun Power serves a distinct niche - domestically manufactured panels for Canadian buyers who need CSA HazLoc certification or who place a premium on local supply chains - and in that context it can be a reasonable fit. The two are not interchangeable; they address different priorities and different geographies.
