The difference in appearance
From the appearance, the four corners of the monocrystalline silicon cell are arc-shaped and have no patterns on the surface; while the four corners of the polycrystalline silicon cell have square corners, and the surface has a pattern similar to ice flowers; the non-crystalline silicon cell is what we usually The thin-film module mentioned, unlike crystalline silicon cells, the grid lines can be seen, and the surface is as clear and smooth as a mirror.
Monocrystalline Solar panel: It is mainly divided into ordinary monocrystalline solar panel and high-efficiency monocrystalline solar panel. Ordinary single crystal is a module composed of ordinary single crystal solar cells in different series and parallel modes. The conversion efficiency of single crystal cells is about 18%-20%, and the surface is mainly blue, with grid lines on the surface. High-efficiency single crystal is a module composed of high-efficiency Sunpower single-crystal solar cells in different series and parallel modes. The conversion efficiency of high-efficiency cells is about 20%-24%, and the surface is also blue without grid lines, but its positive and negative on the back of the solar panel.
Polycrystalline Solar Panel: It is a module composed of polycrystalline solar cells in different series and parallel modes. The conversion efficiency of polycrystalline solar cells is about 14%-18%, and the surface will have some colorful colors. Effervescent, but mostly blue, with grid lines on the surface as well.
Power and Price
The efficiency is arranged from high to low: Sunpower high-efficiency monocrystalline solar panels > ordinary monocrystalline solar panels > polycrystalline solar panels. Prices are arranged from high to low: high-efficiency monocrystalline solar panels > ordinary monocrystalline solar panels > polycrystalline solar panels. Many people consider the relationship between efficiency and price, and most of them will choose ordinary monocrystalline solar panels, whose production process is relatively mature and widely used. Note that the use of solar panels is only in sunlight to generate electricity.
Due to different manufacturing processes and materials, especially due to process conditions, amorphous silicon solar cell modules can only use non-tempered glass, which makes the mechanical strength of amorphous silicon solar cell modules much lower than that of crystalline silicon solar cell modules. , The vibration resistance and impact energy are relatively poor.
