Mono vs Poly solar panel

Monocrystalline solar panels

A monocrystalline solar panel is an assembly in which a number of monocrystalline silicon solar cells are assembled on a single panel in a certain manner. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%. This is the highest photoelectric conversion efficiency of all types of solar cells, but the production cost is so large that it cannot be widely and widely used. To use.

Polycrystalline solar panels

PolyCrystalline solar panels consist of several crystals of silicon in a single PV cell. Several fragments of silicon are melted together to form the wafers of polycrystalline solar panels.

The difference:

1. The arrangement is different. Monocrystalline silicon solar panels are modules composed of high conversion efficiency monocrystalline silicon cells in different series and parallel arrays. Polycrystalline silicon solar panels are photovoltaic modules with different powers arranged in different arrays of polycrystalline silicon solar cells.

2. Different batteries are used. Monocrystalline silicon solar panels use monocrystalline silicon solar cells; and polycrystalline silicon solar panels use polycrystalline silicon solar cells.

3. The conversion efficiency is different. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%; while the photoelectric conversion efficiency is about 12% .

4. The manufacturing cost is different. The manufacturing cost of monocrystalline solar panels is very high, which is much higher than the manufacturing cost of polycrystalline solar panels.

5. In terms of wide application. Although the application scope of the two is the same, because of the higher cost of monocrystalline solar panels, they are not as popular as polycrystalline solar panels in terms of popularity and versatility.
