Monocrystalline silicon solar cell is a kind of solar cell that is currently being developed rapidly. Its composition and production process have been finalized, and the products have been widely used in space and ground facilities. This solar cell uses high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.999%. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%. This is the high photoelectric conversion efficiency of the current types of solar cells, but the production cost is so large that it cannot be widely and widely used. To use. Since monocrystalline silicon is generally encapsulated with toughened glass and waterproof resin, it is durable and has a service life of up to 15 years and up to 25 years.
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 has to be reduced a lot, and the photoelectric conversion efficiency is about 12%. In terms of production cost, it is more expensive than monocrystalline silicon solar cells. It is easy to manufacture, saves power consumption, and has a lower total production cost, so it has been developed in a large amount. In addition, the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of cost performance, monocrystalline silicon solar cells are slightly better.
Do you think that single crystal or polycrystalline solar panels are better? Generally speaking, the solar panels on the market still use more monocrystalline solar panels. Basically, the technology is mature, the market is large, and maintenance is much more convenient. Our solaramigo uses monocrystalline silicon solar panels, which are reliable in quality and easy to maintain. , Is a good choice.
