What is the difference between monocrystalline and polycrystalline solar panels?

Tutorial # 5
Monocrystalline Panel:
Solar cells made of monocrystalline silicon (mono-Si), also called single-crystalline silicon (single-crystal-Si), are quite easily recognizable by an external even coloring and uniform look, indicating high-purity silicon, as you can see on the picture below:
Monocrystalline, also called single crystalline silicon solar panels, are easily recognizable due to their external dark black color.
A good way to separate mono- and polycrystalline solar panels is that polycrystalline solar cells look perfectly rectangular with no rounded edges.
Advantage of Monocrystalline Panel:
1. Monocrystalline solar panels have the highest efficiency rates since they are made out of the highest-grade silicon.
2. Monocrystalline solar panels live the longest. Most solar panel manufacturers put a 25-year warranty on their monocrystalline solar panels.
3. Tend to perform better than similarly rated polycrystalline solar panels at low-light conditions.
4. High-efficiency
5. Smaller installation area needed in comparison with other types.
6. Long life-span (25-year warranty)
7. Good performance under low irradiation conditions.
Disadvantage of Monocrystalline Panel:
1. They are the most expensive solar panels.
2. Circuit breakdown when the solar panel is covered with dirt, shade or snow.
3. Lower performance while increasing the operating temperature.
4. Silicon waste during the manufacturing process
Polycrystalline Panel:
The first solar panels based on polycrystalline silicon, which also is known as polysilicon (p-Si) and multi-crystalline.
Advantage of Polycrystalline Panel
1. The process used to make polycrystalline silicon is simpler and cost less.
2. Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels. This technically means that they perform slightly worse than monocrystalline solar panels in high temperatures. Heat can affect the performance of solar panels and shorten their lifespans. However, this effect is minor, and most homeowners do not need to take it into account.
3. The manufacturing process is simpler and cheaper.
4. There is no silicon waste.
5. They have a higher performance while increasing the operating temperature
Disadvantage of Polycrystalline Panel:
1. Lower efficiency due to low silicon purity.
2. Require higher installation area than monocrystalline solar panel.
3. Lower architecture integration.
