The difference between monocrystalline and polycrystalline solar panelssolar street light-litelsolar manufacturers

11. From the appearance of the module, the four corners of the monocrystalline silicon cell are arc-shaped, and there is no pattern on the surface. The four corners of the polycrystalline silicon cell are square, and the surface has a pattern similar to ice flowers. 22. For the user, there is not much difference between the monocrystalline silicon battery and the polycrystalline silicon battery, and their lifespan and stability are very good. The average conversion efficiency of monocrystalline silicon cells is higher than that of polycrystalline silicon, but the current price is also higher than that of polycrystalline silicon. 3. In the component manufacturing process, polycrystalline cells have fewer production steps than monocrystalline cells, so the energy consumed in the manufacturing process of polycrystalline silicon solar cells is slightly less than that of monocrystalline silicon solar cells, but the power generation of monocrystalline cell modules is higher. The energy consumption ratio is not much different. Comparison of monocrystalline photovoltaic modules and polycrystalline photovoltaic modules 1) Looking at history, the application of monocrystalline photovoltaic panels is earlier than that of polycrystalline photovoltaic panels. Monocrystalline is the big brother and polycrystalline is the younger brother, but the younger brother developed faster later. 2) Looking at the amount, 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%. 3) Looking at the appearance, monocrystalline silicon is dark blue, almost black, polycrystalline silicon is sky blue, brightly colored, the corners of the monocrystalline cell are arc-shaped, and the polycrystalline cell is square. 4) Looking at the conversion rate, the efficiency of single crystal is higher than that of polycrystalline, about 10%-20%. 5) Looking at the cost, the cost of single crystal is slightly more expensive than that of polycrystalline silicon. The cost of different manufacturers is different, and the market price is five cents to ten cents per watt. 6) According to the measured data of attenuation degree, single crystal and polycrystal have their own advantages, and it is impossible to distinguish the attenuation speed from the perspective of single crystal and polycrystal. Relatively speaking, product quality (sealing degree, presence or absence of magazines, cracking or not) has a greater impact on attenuation. 7) Looking at the cost-effectiveness, at present, the cost-effectiveness of polycrystalline is slightly higher than that of monocrystalline, which is only for now. With the reduction of the cost of monocrystalline components, a reversal may also occur in a few years.
