## Summary

Depozit Solar is a Romanian photovoltaic distribution company, registered under the legal name TOPMET BEST SRL and based in Fagaras, Romania. It operates as a reseller of panels from established brands such as Jinko Solar and Canadian Solar, along with Huawei inverters, rather than manufacturing panels of its own. It holds no independent Tier 1 or BloombergNEF bankability status and carries no proprietary cell technology. Q CELLS - traded under the Hanwha Q CELLS brand - is a wholly different entity: a global Tier 1 manufacturer headquartered in Seoul, South Korea, with its technology and innovation center in Thalheim, Germany, built on the assets of the original Q-Cells AG acquired by Hanwha Group in 2012. Q CELLS holds BloombergNEF Tier 1 bankability status and is consistently ranked among the top global module makers, placing third in SolarReviews' 2025 manufacturer rankings. Its U.S. manufacturing footprint alone is planned to reach 8.4 GW of integrated capacity across facilities in Dalton and Cartersville, Georgia. In terms of institutional footprint, Q CELLS operates in a fundamentally different league.

Because Depozit Solar is a distributor and not a panel manufacturer, product comparisons at the technology level are not straightforward. The panels Depozit Solar sells carry the brand and warranty of whichever manufacturer produced them - Jinko Solar or Canadian Solar - so the quality of any purchase depends on the underlying brand, not on Depozit Solar itself. Q CELLS manufactures its own modules under the Q.ANTUM NEO platform, which uses TOPCon cell technology, and targets both premium residential rooftops and mid-scale commercial installations. Its panels carry a 25-year product warranty backed by Hanwha Group's balance sheet, with efficiency ratings confirmed above 22.5% on current production series.

For a buyer comparing these two entities directly, Q CELLS is the clear default: it is a vertically integrated manufacturer with independently verifiable certifications, a global service network, and a strong warranty backstop. Depozit Solar is a regional Romanian distribution outlet that may serve as a convenient local sourcing channel, but the panels it sells should be evaluated on their originating manufacturer's merits, not on Depozit Solar's own standing.
