Smart Insights (data-driven)
  • Efficiency of 24.2% is 1.9pp above the TOPCon 650-700W median (22.4%)
  • Power density of 242.5 W/m² packs 18.8 W/m² more into the same footprint vs TOPCon 650-700W median (223.7 W/m²)
  • At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions
  • At 32.5 kg, this panel is 2.4 kg lighter than TOPCon 650-700W median (34.9 kg) - easier handling during installation
  • 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces

Show series description

Jinko Solar’s Tiger Neo III 66QL6-BDV series are bifacial modules with a dual glass construction, designed to genuinely increase energy yield without complicating the installation project. The application of N-type TOPCon cells translates into excellent performance under challenging conditions – during low light, early morning and evening hours, and overcast skies, where many standard modules lose efficiency. Another distinguishing feature is high bifaciality: the rear side effectively uses reflected light, which is significant on light-colored grounds, membrane-covered roofs, gravel, or elevated structure installations.

This series is tailored for investors who focus on LCOE and aim to “extract more” from the same surface area – from ground-mounted farms and floating projects to large commercial and industrial (C&I) rooftops. In practice, it helps reduce BOS costs, as the high power per module means fewer units, fewer connections, and faster installation. It stands out from the competition by combining efficiency with a focus on stable, long-term yield and structural durability.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
