The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest reaches 24%. ground use. Because monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is durable and its service life can generally reach 15 years, and the maximum can reach 25 years.
The production process of polycrystalline silicon solar panels is similar to that of monocrystalline silicon solar panels, but the photoelectric conversion efficiency of polycrystalline silicon solar panels is much lower. The world's highest efficiency polysilicon solar panels). In terms of production cost, it is cheaper than monocrystalline silicon solar panels, the material is easy to manufacture, saves power consumption, and the total production cost is low, so it has been greatly developed. In addition, the service life of polycrystalline silicon solar panels is shorter than that of monocrystalline silicon solar panels. In terms of cost performance, monocrystalline silicon solar panels are slightly better.
