Mono & Poly-Crystalline Solar Module

Both monocrystalline and polycrystalline solar panels serve the same function in the overall solar PV system: they capture energy from the sun and turn it into electricity. They are also both made from silicon, which is used for solar panels because it is an abundant, very durable element. Many solar panel manufacturers produce both monocrystalline and polycrystalline panels.

Both monocrystalline and polycrystalline solar panels can be good choices for your home, but there are key differences between the two types of technology that you should understand before making your final solar purchase decision. The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from many silicon fragments melted together.

Mono-crystalline and Poly-crystalline solar modules — two of the most common types of photovoltaic (PV) panels used for solar power generation:

Mono-crystalline Solar Modules (Mono-Si)

• Made from a single crystal of silicon.

• Cells are cut from a cylindrical silicon ingot.

• Uniform black or dark color.

• Advantages:

  • Higher Efficiency (18–22%): Better at converting sunlight into electricity.

  • Space Efficient: Needs less roof space for the same power output.

  • Better Performance in low light and high temperatures.

  • Longer Lifespan and generally better build quality.

Poly-crystalline Solar Modules (Poly-Si or Multi-Si)

• Made from multiple silicon crystals melted together.

• Cells have a bluish, speckled appearance.

• Easier and cheaper to manufacture.

Advantages:

• Lower Cost: More affordable upfront.

• Simple Manufacturing Process: Less silicon waste.

• Good return on investment in large-scale projects.
