1. Price. Polysilicon components have a long history of development, relatively mature technology, in price lower than monocrystalline silicon components.
2. Cost performance. Based on the comparison of photoelectric conversion efficiency, attenuation rate, price and other factors, the cost performance of monocrystalline silicon components and polycrystalline silicon components is divided into two parts.
3. 3 Discuss specific situations.
It is more practical to select monocrystalline silicon components for small family photovoltaic power stations with low cost.
For large photovoltaic power stations, polysilicon components are more cost-effective under the same lighting conditions.
However, if the lighting condition is sufficient in this area, the unit of monocrystalline silicon is selected for higher power generation and higher income.
