The Jinko TiGER Neo X20 (66HL4M-BDV) is a high-performance, bifacial glass-glass PV module built for large-scale commercial and utility systems. Using N-type TOPCon cells and Jinko’s HOT 3.0 process, the module minimizes LID/LeTID losses and improves low-light and high-temperature performance for consistently high energy yield. The 132-cell (66×2) glass-glass construction and SMBB cell layout optimize light trapping and current collection while the bifacial design captures additional rear-side irradiance to increase total energy production and reduce LCOE.

Key highlights

• Power range: 625 W – 650 W (STC) with module efficiencies up to ~24%.

• Cell / tech: N-type TOPCon cells, HOT 3.0 process, SMBB technology.

• Bifacial, dual-glass design for elevated rear-side energy generation (bifaciality coefficient per datasheet).

• Excellent mechanical ratings: 5400 Pa front / 2400 Pa rear static test loads (glass-glass).

• Temperature coefficient: Pmax −0.29% / °C (typ.).

• Warranty: 12-year product warranty, 30-year linear power warranty (linear degradation ~0.40% first year stated, ~1% over 30 years per datasheet).

• Environmental / reliability: anti-PID optimization, IEC61215:2021 / IEC61730:2023, IEC61701/IEC62716 tested; IP68 junction box.

• Dimensions / weight: 2382 × 1134 × 30 mm, ~32.4 kg (glass-glass).
  This module is ideal where system designers want the highest per-module power, low long-term degradation and the ability to harvest reflected light (e.g., elevated racking, white roofs, or highly reflective ground). (Details derived from the datasheet you supplied.)
