Introduction of Solar Polycrystalline Series Panels
CNBM Solar photovoltaic (PV) Panel is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.
Polycrystalline Silicon Solar Cells156mm Advantage:
• High efficiency and stable performance in photovoltaic conversion.
• Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
• Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and attractive appearance.
• High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
• High precision patterning using screen printing, ensuring accurate busbar location for ease with automatic soldering a laser cutting.
