Solar panels are mainly divided into the following types (1) Polycrystalline silicon solar cells The production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower, and the photoelectric conversion efficiency is about 12%. . In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is simple to manufacture, power consumption is saved, and the total production cost is lower, so it has been greatly developed. In addition, the service life of polycrystalline silicon Sichuan solar cells is also shorter than that of monocrystalline silicon solar cells. In terms of cost performance, monocrystalline silicon solar cells are slightly better.
