182mm 156Cells 625-645W TOPCon Full Black Bifacial Dual Glass PV Module​

Share:

  • 1. Industry-Leading Power Output
    182mm 156cells design delivers 620–640W, setting benchmarks for commercial/utility projects requiring maximum energy yield per panel.

    2. Bifacial Low-Light Performance
    Full-black front enhances absorption, while rear glass captures diffuse light, boosting output by 10–25% in cloudy or dawn/dusk conditions.

    3. Double-Sided Durability
    Dual tempered glass on both sides resists corrosion, PID, and microcracks, ensuring 30+ years of stable performance in coastal or desert climates.

    4. High-Density Cell Arrangement
    Optimized 156-cell layout with 182mm wafers maximizes space efficiency, reducing installation footprint for area-constrained rooftops or solar farms.

FAQS

Q :

Why choose 620–640W panels for commercial projects?

A :

Industry-leading wattage maximizes energy per panel, cutting installation numbers and costs for large-scale solar farms or industrial rooftops.

Q :

How do bifacial panels perform in overcast conditions?

A :

Rear glass captures scattered light, boosting output by 10–25% during cloudy days or dawn/dusk, outperforming traditional single-sided panels.

Q :

Can these panels withstand coastal climates?

A :

Dual-glass construction resists salt corrosion, humidity, and PID, ensuring 30+ years of stable power generation in harsh environments.

Q :

Do they save space in tight installations?

A :

High-density 182mm cell layout reduces footprint, ideal for rooftops or farms needing maximum power within limited area constraints.
