ZTT-NE66CD-640-670W

N-type BC cell flagship product featuring high efficiency and premium appearance. It is suitable for ground-mounted centralized PV plants and commercial & industrial rooftop distributed PV projects. Supported by intelligent automated production lines, it improves production efficiency, reduces manual intervention, strictly controls manufacturing costs, and guarantees consistent product quality across all batches.

Product Advantages
  • High Power: Adopting N‑type back‑contact (BC) cell technology, the module delivers a maximum power output of 670 W and a peak photoelectric conversion efficiency of 24.8%.
  • High Power Generation:Free from front‑side busbar shading, the module features a larger light‑receiving area, delivering outstanding low‑light response and boosting power generation over the full lifecycle.
  • High Reliability:With a full‑black, busbar‑free front surface, the module offers excellent PID resistance and low LID degradation, achieving first‑year degradation of less than 1%.
  • Enhanced Safety:Effective suppression of local overheating keeps module temperatures under shaded conditions markedly lower than those of conventional modules.
