Comparison of single crystal and polycrystalline

Look at history, the application of single crystal photovoltaic panels is earlier than polycrystalline photovoltaic panels, single crystal is the big brother, polycrystalline is the younger brother, but the younger brother later developed faster.

Seeing the dosage, the application of polysilicon in power stations is much higher than that of monocrystalline silicon, with monocrystalline silicon accounting for 30% and polycrystalline silicon accounting for 70%.

Look at the appearance, single crystal silicon dark blue, almost black, polysilicon sky blue, bright colors, single crystal cell four corner arc, polycrystalline cell square.

Look at the conversion rate, the single crystal efficiency is higher than polycrystalline, about 10%-20%.

Look at the cost, the cost of single crystal is slightly more expensive than polycrystalline, the cost of different manufacturers is different, the market price is one watt high five cents to one cent.

Looking at the measured data of attenuation, it is shown that single crystals and polycrystals have their own advantages, and it is impossible to distinguish the decay speed from single crystal and polycrystalline angle. Relatively speaking, product quality (sealing degree, presence or absence of magazines, whether it is cracked) has a greater impact on attenuation.

The battle for single polycrystals is actually the benevolent seeing the wise and seeing wisdom. There is no need to always compare them. As long as the quality is reliable and the system is stable, it is no problem to choose which one.
