1. Different in appearance
Judging from the appearance, the four corners of a monocrystalline silicon battery chip are arc-shaped, with no patterns on the surface; The four corners of the polysilicon battery chip present square corners, with a surface pattern similar to ice flower. The background color of monocrystalline silicon is black or light blue, while the background color of polycrystalline silicon is mostly blue or colored.
2. Different in use
The average conversion efficiency of monocrystalline silicon batteries is about 1% higher than that of polycrystalline silicon. However, because monocrystalline silicon batteries can only be made into quasi squares (with circular arcs on all four sides), when forming solar panels, there will be a portion of the area that is not filled up; Polycrystalline silicon is square, so there is no such problem.
3. Different manufacturing processes
The energy consumed in the manufacturing process of polysilicon solar cells is about 30% less than that of monocrystalline silicon solar cells. Therefore, polysilicon solar cells account for a large share of the total global production of solar cells, and their manufacturing costs are also smaller than monocrystalline silicon cells.
4. Different dosage
The application of polysilicon in power stations is far higher than monocrystalline silicon, with monocrystalline silicon accounting for 30% and polycrystalline silicon accounting for 70%.
Monocrystalline silicon polysilicon is a raw material used for manufacturing solar panels. Silicon is an extremely rich element on the earth, almost ubiquitous, and can be said to be inexhaustible. Using silicon as a solar cell, there is no shortage of raw materials. The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage should be stable. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, with a photoelectric conversion efficiency of about 12%, slightly lower than that of monocrystalline silicon solar cells. However, the material manufacturing is simple and convenient, with low power consumption and low total production cost, so it has been greatly developed. Advantages: The polycrystalline plate receives light from multiple directions, with good directionality. In practical testing, assuming that one hand is used to block the sun's rays and leave a shadow on the surface of the solar power generation panel, the reduction in the power generation current of the polycrystalline panel is smaller than that of the single crystal panel, which is the advantage of the polycrystalline panel. And his price is relatively low
The conversion efficiency of single crystals is high and expensive; Polycrystalline conversion efficiency is low and inexpensive.
There are many polycrystals, or polycrystals, in the domestic market.
The market in Japan has been very hot recently
5. Volume: Compared to polycrystalline plates with the same power, the area of the polycrystalline plate is slightly larger than the area of the single crystal plate.
What kind of inverter is best used with? If you want to achieve high conversion efficiency and long-term cost savings, it is best to choose MPPT inverters. For example, if your roof space is limited, it is definitely necessary to consider single crystals with high conversion efficiency and MPPT inverters with high conversion efficiency
If you have enough space to place solar panels, you can consider polycrystalline solar panels or PWM inverters.
You can consider purchasing an inverter from daxtromn power.
