What is the difference between poly panel and mono panel ?
Published by TANFON SOLAR March 12,2020

solar panelMonocrystalline solar panels and polycrystalline solar panels are both types of solar panels, but there are differences in crystal arrangement and other aspects. The differences are:

  1. The arrangement is different. The single crystal silicon solar panel is a module body composed of single crystal silicon cells with high conversion efficiency according to different string and parallel array methods. Polycrystalline silicon solar panels are photovoltaic modules with different powers arranged in different arrays using polycrystalline silicon solar cells.


  1. Different battery slices are used. Monocrystalline silicon solar panels use monocrystalline silicon solar cells; while polycrystalline silicon solar panels use polycrystalline silicon solar cells.

To put it simply, the difference between single crystal silicon and polycrystalline silicon is their atomic structure arrangement. Single crystals are ordered, and polycrystals are disordered. This is mainly determined by their processing technology. Polycrystalline is mostly produced by casting. That is, the silicon material is directly poured into the pot to melt and set, and the single crystal is modified by Siemens method. The straight drawing process is a process of atomic structure reorganization. To our naked eyes, the surface of the single crystal silicon looks the same, and the surface of the polysilicon looks like there is a lot of broken glass in it, shining.

in conclusion:

Monocrystalline solar panel: no pattern, dark blue, almost black after packaging, suitable for use in places with strong light.

Polycrystalline solar panel: there are patterns, there are polycrystalline colorful and polycrystalline less colorful, like snowflake crystal pattern on snowflake iron sheet, light blue, suitable for use in cold and snowy areas.
