  • Technical Parameters of Polycrystalline Silicon Photovoltaic Panels

    Technical Parameters of Polycrystalline Silicon Photovoltaic Panels

    Polycrystalline solar panels are composed of solar cells made from multiple fragments of silicon crystals that have been melted together. They are dark blue and square-structured. 5% has been fabricated without the involvement of anti-reflecting coating. It serves as an intermediate between amorphous silicon, which lacks long-range order, and monocrystalline silicon, which has a continuous crystal structure. Polycrystalline silicon exhibits heightened sensitivity to temperature variations and has a short lifespan, resulting in lower efficiency, typically ranging between 12% and 15%. In contrast. The following article highlights the outcomes of research on the output parameters of solar panels based on polycrystalline silicon, installed in Pap district of Namangan region, after several years of operation.
