Monocrystalline solar panels and polycrystalline solar panels are a type of solar panel, but they are different in terms of the arrangement of the crystals. Their differences are:
1. Monocrystalline silicon solar panels are components composed of monocrystalline silicon cells with high conversion efficiency distributed in different series and parallel arrays. Polycrystalline silicon solar panels use polycrystalline silicon solar cells arranged in different arrays to form photovoltaic modules of different powers.
2. The drum sheets 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. Photoelectric conversion efficiencyThe electrical efficiency of monocrystalline silicon solar cells is about 15%, the highest reaching 24% while the photoelectric conversion efficiency is about 12% (on July 1, 2004, Japan Sharp launched the polycrystalline silicon solar cell the most efficient in the world with an efficiency of 14.8%).
4. Manufacturing costs are different. The manufacturing cost of monocrystalline solar panels is very high, much higher than the manufacturing cost of polycrystalline solar panels.
5.Extensive application. Although the application scope of both is the same, monocrystalline solar panels are not as popular and widespread as polycrystalline solar panels due to their higher cost.
