What is the difference between monocrystalline and polycrystalline solar panels?
According to solar energy experts, the manufacturing process of monocrystalline and polycrystalline is different, and the composition is also different, but the final product (solar panel) has the same effect. The difference between the previous two lies in the photoelectric conversion rate. Single crystal has always been more efficient than polycrystalline. Even in the laboratory, this is still the case. In addition, the material of single crystal is better than that of polycrystalline.
It is not easy to damage during the production process. In addition, in terms of appearance, single crystals are generally Monochromatic (the conventional ones are blue and black. Basically, it is blue in foreign countries. Most of the surface in China is blue, but the color will become black after lamination.
The color of polycrystalline is very mixed, and there are monochrome blue. Color. There are also colored ones. The price: single crystal is normally higher than polycrystalline (of course, this is not to say that polycrystalline is inferior to single crystal, but the production cost of polycrystalline is much lower than single crystal, and the output of polycrystalline Much larger than single crystal) Su Fu's warm reminder: Regardless of single crystal or polycrystalline battery, the power cannot be seen by the eyes, and the eyes can only distinguish the appearance of the battery, whether there are color differences, missing corners, etc., power It needs to be tested with a cell tester, and it must be calibrated by the authoritative department's testing standard (ie: IEC61215 through the international standard) before testing, otherwise the tested data will be inaccurate.
