What cell technology and busbar configuration do you use?


img

182 mm or 210 mm half-cut cells ( TOPCon). Premium lines: 16BB SMBB with 0.25 mm zero-gap ribbons, reducing Rs by ≤15 %.

img

What is the exact PID resistance mechanism?


img

PID-free per IEC 62804: anti-PID EVA (Vm ≤1,000 V), Na⁺-blocking POE options, and cell-level encapsulation with <1 % power loss after 192 h at 85 °C/85 % RH.

img

What are the mechanical load ratings?


img

Front: 5,400 Pa (snow); rear: 4,000 Pa (wind). Tested per IEC 61215 with 1.5× safety factor. Bifacial models use 2.0–2.5 mm dual-glass for 8,100 Pa front.

img

What is the bifaciality factor and rear-side mismatch loss?


img

Measured bifaciality: 70 ±5 % (STC rear / front). Rear mismatch <2 % at 200 W/m² rear irradiance (PVEL 2024). Gain modeled in PVsyst v7.4+.

img

What junction box and connector specs do you use?


img

IP68, 3-diode split J-box (TUV 1,500 V). MC4-EVO2 or QC4.10-35 connectors, 4 mm² tinned Cu cable, ≤0.35 %/year contact resistance drift.

img

What is the NOCT and temperature coefficient breakdown?


img

NOCT: 43 ±2 °C (800 W/m², 20 °C ambient, 1 m/s). Coefficients:  
  - Pmax: –0.34 %/°C  
  - Voc: –0.27 %/°C  
  - Isc: +0.05 %/°C  
  - Verified per IEC 61215 Ed.2.
