## Summary

AIKO is a Chinese solar manufacturer headquartered in Guangzhou, founded in 2009, that has grown into one of the most prominently positioned producers of premium modules globally. The company achieved BloombergNEF Tier 1 status - a bankability benchmark confirming non-recourse financing by at least six commercial banks across multiple projects - and was reporting an annual production capacity in the range of 20 to 35 GW as of early 2026, placing it firmly among the leading Chinese module makers. VNS Bulgaria Ltd., by contrast, is a Bulgarian distributor and wholesaler of solar equipment rather than a manufacturer in its own right. The company resells modules from established Chinese brands including LONGi, Jinko Solar, JA Solar, Trina Solar, Canadian Solar, and Risen Energy, and also stocks inverters and storage products. VNS Bulgaria holds no independent Tier 1 or bankability designation; its market role is that of a regional procurement intermediary. In terms of institutional footprint and manufacturing credibility, AIKO holds a substantially stronger position.

AIKO's product line centers on its proprietary ABC (All-Back-Contact) technology, which moves all electrical contacts to the rear of the cell, eliminating front-surface shading and enabling certified panel efficiencies above 24% - with its Neostar 3P line reaching 25.0% in independent tests. The technology also delivers a notably low temperature coefficient and reduced first-year degradation, making AIKO panels most competitive for premium residential rooftops and space-constrained commercial installations where output per square meter is critical. VNS Bulgaria, operating as a distributor, carries a broader technology mix that reflects whatever its upstream suppliers manufacture - PERC, TOPCon, and HJT modules are all potentially available depending on which brand is sourced. Its "product range" is therefore derivative of the manufacturers it represents rather than a reflection of any in-house R&D.

For a buyer seeking high-efficiency panels backed by a direct manufacturer warranty and bankable Tier 1 credentials, AIKO is the clear choice. VNS Bulgaria serves a different function - it is a regional procurement channel useful for projects that prioritize supply-chain flexibility, multi-brand sourcing, or local logistics support in the Balkans and Central Europe, not a competing manufacturer.
