## Summary

Depozit Solar is a Romanian photovoltaic distribution company based in Fagaras, Brasov, operating under the parent entity TOPMET BEST SRL. It acts as a wholesale reseller of panels from established brands such as Jinko Solar and Canadian Solar, and of inverters and storage equipment from Huawei and others, serving professional installers as well as residential and commercial clients in the local market. As a distributor rather than a manufacturer, it does not carry BloombergNEF Tier 1 certification and has no independently rated production capacity of its own. AIKO Solar, by contrast, is a Chinese manufacturer headquartered in Shanghai whose R&D team pivoted to N-type All Back Contact (ABC) cell technology in 2016 and brought commercial modules to market in 2022. AIKO achieved BloombergNEF Tier 1 status in Q3 2024 and, according to published Tier 1 list data, operates roughly 20 GW of annual production capacity across multiple gigafactories in China. AIKO carries a substantially larger institutional footprint than Depozit Solar.

On the product side, Depozit Solar offers no proprietary modules - its catalog reflects the technology mix of the brands it stocks, which currently includes TOPCon and PERC options from its main suppliers. AIKO's own line is built entirely around its ABC architecture, an N-type design that places all cell contacts on the rear surface to maximize active light absorption and eliminate front-side shading losses. Independent installer surveys and efficiency rankings have consistently rated AIKO among the highest-performing mass-produced panels commercially available, making them well suited to premium residential rooftops and commercial projects where power density and long-term degradation guarantees are the deciding factors.

A direct comparison is structurally difficult because the two occupy different roles in the supply chain. Buyers seeking a bankable, manufacturer-backed module with verified technology credentials will find AIKO the more relevant choice. Depozit Solar is a regional procurement channel whose value lies in local availability and multi-brand sourcing in the Romanian market, not in any proprietary product advantage of its own.
