What is the difference between polycrystalline solar panels and monocrystalline solar panels?

(1) Monocrystalline silicon solar cells The current photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, the highest reaching 24%. It is currently the highest photoelectric conversion efficiency among all types of solar cells, but the production cost so high that it cannot yet be widely and universally used in large numbers. Since monocrystalline silicon is typically encapsulated in tempered glass and waterproof resin, it is strong and durable, with a lifespan of typically up to 15 years and up to 25 years. (2) Polycrystalline silicon solar cells The manufacturing 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. Its effectPhotoelectric conversion efficiency is about 12% (Japan July). January 1, 2004 Sharp launches the world's most efficient polycrystalline silicon solar cell, with an efficiency of 14.8%). In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The material is easy to manufacture, saves energy, and the overall production cost is low, so it has been widely developed. In addition, the lifespan of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of performance-price ratio, monocrystalline silicon solar cells are slightly better.
