Description
Jinko Bifacial Solar 640w Solar Panel Main Features
The JinkoSolar 640W bifacial solar panel, typically part of the Tiger Neo series (Model JKM640N-78HL4-BDV), is a high-efficiency module utilizing N-type TOPCon technology to generate power from both sides.
Designed for utility-scale and large commercial projects, it features a dual-glass structure that enhances durability and performance in harsh environments.
Key Features
- Bifacial Technology: Captures sunlight on both the front and rear sides, providing a general power gain of 5% to 25% depending on ground reflectivity (albedo).
- N-Type TOPCon Cells: Utilizes SMBB (Super Multi Busbar) and Hot 2.0 technology to improve light trapping, current collection, and reliability while reducing LID (Light Induced Degradation).
- Enhanced Durability: Certified to withstand high mechanical loads, including wind loads up to 2400 Pa and snow loads up to 5400 Pa.
- Superior Warranty: Offers a 12-year product warranty and a 30-year linear power warranty with a low annual degradation rate of approximately 0.4%
