1. Single crystal solar panel
The components of single crystal battery board are the same, but its battery sheet is made of single crystal silicon. (q: what is monocrystalline silicon? A: monocrystal of silicon. It is a crystal with basically complete lattice structure. Different directions have different properties, and it is a good semiconducting material. The purity is required to reach 99.9999%, or even above 99.999999%. It is used to manufacture semiconductor devices, solar cells, etc. it is drawn from high-purity polycrystalline silicon in a monocrystal furnace.), The advantage of monocrystalline silicon is that its conversion rate is higher than that of polycrystalline silicon. Under the same area, it can generate more electricity! Reduced land rent and support costs. And in terms of performance (attenuation, etc.), it is slightly better than polysilicon, but in terms of manufacturing cost, it is higher than polysilicon. Therefore, the price of single crystal battery panel is higher than that of polycrystalline silicon battery panel!
2. Polycrystalline solar panel
The composition and structure of polycrystalline battery panel are exactly the same as that of single crystal, except that its battery sheet is made of polycrystalline silicon. After the introduction of polycrystalline battery board, because of its low price, and its performance is not much different from that of single crystal! The market has always been very popular. Moreover, due to the continuous innovation of technology in recent years, the gap between polysilicon battery panels and polycrystalline cells in performance and conversion rate is not very large, which can be almost ignored. But there is a big difference in price (the price of single polycrystalline before the 531 new deal can differ by a few cents a watt). Therefore, polysilicon is more popular in the market. (however, after the 531 new deal, the price of single crystal battery panels was too high and the income was too poor, so the price reduction of single crystal battery panels was relatively large.)
