The difference between monocrystalline and polycrystalline solar panels of solar street light:
1.The arrangement is different. The solar panel of the monocrystalline silicon solar street light is a module body composed of monocrystalline silicon cells with high conversion efficiency in different series and parallel arrays. Polycrystalline silicon solar panels are photovoltaic modules with polycrystalline silicon solar cells arranged in different arrays to form different powers.
2. The batteries used are different. Monocrystalline silicon solar panels use monocrystalline silicon solar cells; polycrystalline silicon solar panels use polycrystalline silicon solar cells.
3.The conversion efficiency is different. The photoelectric conversion efficiency of monocrystalline silicon solar street light cells is about 15%, and the highest is 24%; while the photoelectric conversion efficiency is about 12% (on July 1, 2004, Japan's Sharp listed the world's highest efficiency polycrystalline silicon solar cell with an efficiency of 14.8%).
4. The manufacturing cost is different. The production cost of monocrystalline solar panels is very high, which is much higher than that of polycrystalline solar panels.
5. Wide application. Although both have the same range of applications, monocrystalline solar panels are not as popular and widespread as polycrystalline solar panels because of their higher cost.
