Guide: There are many kinds of outdoor solar garden lights. How to choose practical and practical? The most important part of solar lighting products is solar cells, and the solar cell conversion efficiency and stability made by different solar cell modules are different. The difference between learning, that is, learning to choose a good outdoor solar garden lights.

    Comparison of single crystal silicon, polycrystalline silicon, amorphous silicon solar cell modules Table 4-4 comprehensively compares the electrical properties (efficiency, stability, sensibility, consistency) and price of single crystal silicon, polycrystalline silicon, and amorphous silicon solar cell modules. And the difference in mechanical strength.

Comprehensive comparison of three solar modules Component material

   
    (1) The highest conversion efficiency in terms of electrical performance is monocrystalline silicon solar cell modules, which are slightly lower than monocrystalline silicon solar cell modules, and amorphous silicon solar cells compared to crystalline silicon solar cell modules. Conversion efficiency is relatively low, only 6% to 8%.

    The stability of single crystal silicon and polycrystalline silicon solar cell modules is good, and amorphous silicon solar cells have poor stability due to photo-induced attenuation effects. The crystalline silicon solar cell module is suitable for use in high light conditions, while the amorphous silicon solar cell has relatively poor light resistance. The consistency of crystalline silicon solar cells is good, while the consistency of amorphous silicon solar cells is poor.

    (2) In terms of price, the main material of silicon solar cells is silicon, which accounts for about 2/3 of the component manufacturing cost. Currently, silicon materials are quite expensive. Amorphous silicon is much less than silicon silicon for crystalline silicon solar cell modules, so amorphous silicon solar cell modules are less expensive than crystalline silicon solar cell modules.

    (3) Mechanical strength Due to different manufacturing processes and materials, especially due to process conditions, amorphous silicon solar modules can only use non-tempered glass, which makes the mechanical strength of amorphous silicon solar modules and crystalline silicon solar energy. The battery pack is much lower, and the shock resistance and impact resistance are relatively poor.

    In terms of practical use, solar cells made of single crystal silicon and polycrystalline silicon are more practical. Amorphous silicon is relatively inexpensive. In the case of a sufficient budget, it is recommended to buy solar garden lights with monocrystalline silicon and polycrystalline silicon as materials, which can greatly increase the experience when used. Longxing Industrial specializes in producing quality solar lighting products.
