Jinko 640W JKM640N-66HL4M-BDV N-Type Bifacial (SFR)

The Jinko EAGLE G7B JKM640N-66HL4M-BDV module is a high-efficiency, bifacial photovoltaic panel based on N-type TOPCon and half-cell technology, designed for commercial and industrial installations requiring high power and long-term reliability. The variant with a power of STC 640 W provides enhanced efficiency and energy benefits from light reflection on the back side of the module.

Manufacturer: Jinko Solar — a global company listed on NYSE (since 2010), a Bloomberg Tier-1 manufacturer. The company uses automated production lines supported by artificial intelligence, is vertically integrated, and operates factories in the USA and Vietnam. EAGLE modules utilize N-type cells with in-house TOPCon for better performance and reliability.
