1. Monocrystalline silicon solar panels have high cell conversion efficiency and good stability, but the cost is high.

2. The cost of polycrystalline silicon solar panels is low, and the conversion efficiency is slightly lower than that of Czochralski monocrystalline silicon solar panels. Various defects in the material, such as grain boundaries, dislocations, micro-defects, and impurities in the material carbon and oxygen, and the process The contamination of transition group metals in China is considered to be responsible for the photoelectric conversion rate of polycrystalline silicon solar panels, which has been unable to break through the 20% mark.

Polycrystalline silicon has a better low-light power generation effect than monocrystalline silicon.

It is recommended to use monocrystalline silicon solar panels for places with a sunshine coefficient of more than 4h, and polycrystalline silicon solar panels for places with a sunshine coefficient of less than 4h.
