What is the difference between single crystal and polycrystalline solar panels? According to solar energy experts, the manufacturing process of single crystal and polycrystalline is different, and the composition is also different, but the final finished product (solar panel) has the same effect.
The difference between the two before is that the photoelectric conversion rate is different. The conversion efficiency of single crystal is always higher than that of polycrystalline, even in the laboratory. In addition, the material of single crystal is better than that of polycrystalline, which is not easy to be damaged in the production process.
In addition, in terms of appearance, single crystals are generally monochromatic (conventional ones are blue and black. Most of the surfaces in foreign countries are mostly blue, while most of the surfaces in China are blue, but the color will turn black after lamination. The polycrystalline colors are very mixed, including monochromatic blue and color)
Price: single crystal is normally higher than polycrystalline (of course, this does not mean that polycrystalline is not as good as single crystal, but that the production cost of polycrystalline is lower than that of single crystal, and the output of polycrystalline is greater than that of single crystal)
HuanQi solar warm tips: no matter single crystal or polycrystalline cell, the power can’t be seen by the eyes. The eyes can only distinguish the appearance of the cell, whether there is color difference, missing angle, etc. the power should be detected by the cell tester, and must be calibrated by the standard chip detected by the authority department before testing, otherwise the test data is inaccurate.
