For users, monocrystalline silicon cells and polycrystalline silicon cells are not very different, their life and stability are very good. Although the average conversion efficiency of monocrystalline silicon batteries than polycrystalline silicon about 1% higher, but because monocrystalline silicon batteries can only be made into a quasi-square (four sides are arcs), so when the composition of solar panels when there will be a part of the area is not full; and polycrystalline silicon is square, so there is no such a problem, their advantages and disadvantages are as follows:

Crystalline silicon module: single module power is relatively high. Under the same footprint, the installed capacity is higher than thin film components. However, the components are thick and fragile, with poor high-temperature performance, poor low-light performance, and high annual attenuation rate.

Thin-film module: the power of single module is relatively low; poor stability, need to run for a long time before stabilization. However, the power generation performance is high, high temperature performance is good, low light performance is good, the shadow blocking power loss is small, and the annual attenuation rate is low. Wide range of application environments, beautiful, environmentally friendly.

Monocrystalline silicon, polycrystalline silicon, amorphous silicon battery manufacturing process differences

Polycrystalline silicon solar cell manufacturing process consumes about 30% less energy than monocrystalline silicon solar cells, so polycrystalline silicon solar cells accounted for a large share of the total global solar cell production, manufacturing costs are also less than monocrystalline silicon batteries, so the use of polycrystalline silicon solar cells will be more energy-efficient, environmentally friendly!

In fact, there are many semiconductor materials available for the manufacture of solar cells, with the development of the materials industry, solar cells will be more and more varieties. At present, the research and trial production of solar cells, in addition to silicon series, there are cadmium sulfide, gallium arsenide, copper indium selenide and many other types of solar cells, to name a few, usually these materials are used to make amorphous silicon batteries.

Therefore, when we choose photovoltaic modules, it is recommended to choose crystalline silicon photovoltaic modules according to the actual situation of the more mature products, for monocrystalline, polycrystalline, there has been a debate, we installers of home photovoltaic power generation system power generation does not make much difference, monocrystalline use of the area will be relatively high, monocrystalline utilization in the area of the utilization will be relatively good; polycrystalline market proportion is relatively high, the application of the more widely used, the price aspect is also have Certain advantages, but we have to understand one thing, for the same power of the photovoltaic system, for the power generation is the same.
