What is the Difference Between Monocrystalline and Polycrystalline Panels

Monocrystalline and polycrystalline solar panels are both made of silicon, but they are manufactured in different ways. Monocrystalline solar panels are made from a single crystal of silicon, while polycrystalline solar panels are made from multiple silicon crystals that have been melted together.

Monocrystalline Solar Panels

  • Pros:
    • More efficient than polycrystalline solar panels
    • Look more uniform (black)
    • Can withstand high temperatures better
  • Cons:
    • More expensive than polycrystalline solar panels
    • Can be more difficult to find

Polycrystalline Solar Panels

  • Pros:
    • Less expensive than monocrystalline solar panels
    • More readily available
    • Can be made in a variety of colors
  • Cons:
    • Less efficient than monocrystalline solar panels
    • Can have a more “blotchy” appearance
    • Not as resistant to high temperatures


Ultimately, the best type of solar panel for you will depend on your individual needs and budget. If you are looking for the most efficient panels and are willing to pay a premium, then monocrystalline solar panels are the way to go. If you are on a budget and are looking for more readily available panels, then polycrystalline solar panels are a good option.

Here is a table that summarizes the key differences between monocrystalline and polycrystalline solar panels:
