Nowadays, the penetration rate of solar street lights is getting higher and higher. Not only in cities, but also in many rural areas, solar street lights are installed. Let’s not talk about its advantages. Solar street light panels are divided into monocrystalline and polycrystalline. Many customers are actually very entangled in their choice. They don't know which one to choose and which is more cost-effective. Below, our solar street lamp manufacturer will give you an analysis of whether to use monocrystalline or polycrystalline solar panels.

The difference between single crystal and polycrystalline battery version:
①The photoelectric conversion rate is different, and the conversion efficiency of single crystal is always higher than that of polycrystal;
②The material of single crystal is better than polycrystalline, and it is not easy to be damaged during the production process;
③In terms of appearance, single crystals are generally monochromatic (the conventional ones are blue and black. Basically, they are blue in foreign countries. Most of the surface in China is blue, but the color will become after lamination. Black, polycrystalline color is very mixed, both monochrome blue. There are also colored)
⑤Price: Single crystal is normally higher than polycrystalline (Of course, this is not to say that polycrystalline is inferior to single crystal, but the production cost of polycrystalline is much lower than single crystal, and the output of polycrystalline is much larger. In single crystal)
For users, there is not much difference between monocrystalline silicon cells and polycrystalline silicon cells. The life and stability of monocrystalline silicon cells and polycrystalline silicon cells are very good. Although the average conversion efficiency of monocrystalline silicon cells is about 1% higher than that of polycrystalline silicon cells, because monocrystalline silicon solar cells can only be made into a quasi-square shape (the corners are arcs), it is necessary when forming solar cell modules. Part of the area is not full, and the polycrystalline silicon solar cell is square. This problem does not exist. Therefore, the efficiency of the solar cell module is almost the same.

 
In short, for solar street lights, combined with the price, our solar street light manufacturers believe that polycrystalline solar panels are more cost-effective and more suitable for general use, while single crystals are more suitable for government projects with specific requirements. Under normal circumstances Polycrystalline solar panels are sufficient for use.
