The Difference Between Monocrystalline Silicon and Polycrystalline Silicon in Solar Panels

I. The difference between polycrystalline silicon and monocrystalline silicon


1. The difference in appearance between polycrystalline silicon solar panels and monocrystalline solar panels


First, let's look at the appearance of the solar panel module. The four corners of the monocrystalline silicon solar panel are arc-shaped and there is no pattern on the surface. On the other hand, the four corners of the polycrystalline silicon monocrystalline solar panel are square corners, and the surface has a pattern similar to ice flowers.


2. The difference in conversion rate between polycrystalline silicon solar panels and monocrystalline silicon solar panels


In terms of conversion rate, the conversion rate of monocrystalline silicon solar panels is higher than that of polycrystalline silicon, so the corresponding price is also higher than that of polycrystalline silicon solar panels. However, there is not much difference between polycrystalline silicon solar panels and monocrystalline silicon solar panels in use, and the life and stability are very good.


3. The production process of polycrystalline silicon solar panels and monocrystalline solar panels is different


In terms of manufacturing comparison, the production process of monocrystalline silicon solar panels is more complicated than that of polycrystalline silicon solar panels, which is why the conversion rate of monocrystalline silicon solar panels is higher than that of polycrystalline silicon solar panels.


II. How to choose monocrystalline silicon solar panels and polycrystalline silicon?


1. The development


The application of monocrystalline silicon solar panels is earlier than that of polycrystalline silicon solar panels, but the current development of polycrystalline silicon solar panels is faster than that of monocrystalline silicon solar panels.


2. The dosage


The application of polycrystalline silicon solar panels in power stations is much higher than that of monocrystalline silicon solar panels, with monocrystalline silicon solar panels accounting for 30% and polycrystalline silicon solar panels accounting for 70%.


3. The appearance


Monocrystalline silicon solar panels are dark blue, almost black, polycrystalline silicon is sky blue, and the color is bright; monocrystalline solar panels are arc-shaped with four corners, and polycrystalline solar panels are square.


4. The conversion rate


The efficiency of monocrystalline silicon solar panels is higher than that of polycrystalline solar panels, around 10%-20%.


5. The cost


The cost of monocrystalline silicon solar panels is slightly more expensive than that of polycrystalline silicon solar panels. The cost varies from manufacturer to manufacturer, and the market price is five cents to one dime per watt.


6. The measured data display of attenuation


Monocrystalline silicon solar panels and polycrystalline have their own advantages and disadvantages, and it is impossible to distinguish the decay speed from the single crystal silicon solar panel and polycrystalline perspective. Relatively speaking, product quality (sealing degree, presence or absence of impurities, and whether it is cracked) has a greater impact on attenuation.


7. The price/performance ratio


At present, the price-performance ratio of polycrystalline solar panels is slightly higher than that of monocrystalline silicon solar panels, but it is only for now. As the cost of monocrystalline modules decreases, a reversal may occur in a few years.
