Solar cells are made of silicon and they all have one function, and that is turning sunlight into DC electricity. Most solar panel manufacturers assemble solar panels from both mono and poly cells. A solar panel consists of solar cells, copper wire, aluminum frame and coating, but the efficiency of the solar cells determine the overall output of the solar panel and the solar power system which is made of solar panels.

Some homeowners may wonder which type of solar panels are better for their house, but mono and poly solar panels can both be good choices depending on their unique house specifications. There are certain differences between the two types of technology that you need to understand before deciding which panel type works better for your residential solar panel installation. Most solar installers carry both panel types, so they can offer you the right panel type, but it is important for you to work with an experienced Energy Advisor who can give you the best recommendation. If you are not sure which panel type is a better choice for you, please contact us.

Below are the main differences between monocrystalline and polycrystalline solar panels:


  • Monocrystalline panels have uniform (usually black) color:
    • This is because silicon is formed into bars and cut into wafers to make monocrystalline cells which are used to make monocrystalline solar panels.
  • Polycrystalline panels have a blue tint splintered color pattern
    • This is because fragments of silicon are melted together to form the wafers to make polycrystalline cells which are used to make polycrystalline solar panels.


  • Monocrystalline panels are usually more expensive
  • Polycrystalline panels are usually less expensive


  • Monocrystalline panels offer a higher efficiency
  • Polycrystalline panels offer a lower efficiency

Performance in high temperatures

  • Monocrystalline panels perform better in high temperatures
  • Polycrystalline panels lose up to 50% of their efficiency in high temperatures

Some examples of Monocrystalline panels include:

  • SunPower Panels
  • SolarWorld Panels
  • Canadian Solar Panels

Some examples of Polycrystalline panels include:
