Monocrystalline silicon solar panels and polycrystalline silicon solar panels are two common types of solar panels, which have certain differences in performance and appearance. Here are some key features that can help you distinguish between monocrystalline silicon solar panels and polycrystalline silicon solar panels:

Appearance color: Monocrystalline silicon solar panel: Because monocrystalline silicon material is relatively pure, the color of monocrystalline silicon solar panels is relatively uniform, presenting a dark blue or black appearance. Polycrystalline silicon solar panel: Polycrystalline silicon material contains multiple grains with obvious grain boundaries between them, resulting in a mixed color of polycrystalline silicon solar panels, presenting a light blue or blue gray appearance.

Appearance texture: Monocrystalline silicon solar panel: The crystal structure of monocrystalline silicon solar panels is relatively regular, with no obvious grain texture on the surface, presenting a smooth surface. Polycrystalline silicon solar panel: The surface of polycrystalline silicon solar panel has obvious grain texture, presenting irregular crystal structure.

Cell shape: Monocrystalline silicon solar panel: Monocrystalline silicon solar panels are cut in a circular or elliptical shape, so the edges of the cells may have missing corners, resembling octagons or circles. Polycrystalline silicon solar panels: Polycrystalline silicon solar cells are usually square or rectangular, with neat edges and no missing corners.
