Mono-crystalline cells are manufactured using a single silicon crystal. And Since they are manufactured from high-quality silicon crystals, they have high efficiency, better low light performance, and a long life span. Polycrystalline (Poly), as the name suggests, is made from melting many silicon crystals. They are easy to manufacture, economical, and produce less wastage.
However, quick changes in solar module manufacturing procedures are starting to limit this cost advantage that poly modules enjoyed over their mono counterparts. Mono PERC module is the latest innovation and can currently be used as mono-crystalline and polycrystalline cells. Conventionally, solar cells include an emitter layer on the front surface and a black coating on the rear side.
Why are Mono PERC panels a better choice for your rooftop solar plant system
Mono PERC panels are recognized to have higher efficiency in performing under low light situations too. These panels contain a high photovoltaic capacity and produce enriched power during lesser sunlight. The exclusive design of Mono-crystalline panels not only appears good but also has scientific importance. The unique design increases the contact area with sunlight and helps generate more electricity. The following are some other advantages of Mono PERC panels over polycrystalline panels:
- The cells of Mono PERC panels are coated with silicon nitride, which helps to reduce glare from sunlight, thereby increasing power generation.
- Monocrystalline panels have better heat resistance capabilities. This helps improve system efficiency and avoid failures or defects that can become serious management problems.
- The top surface of Mono PERC solar module is coated with phosphorus which helps in generating a complex electric field for better productivity. This is caused because of the negatively charged electric orientation as compared to the positive electric orientation underneath it.
- The unique pyramid pattern of the mono PERC cells provides a large surface area. This is why this type of panel has excellent power generation capacity.
- The generated electricity is then gathered through complex metal conductors, which are known to deliver smoothness to the system.
- Mono-crystalline panels have durability. The panels are known to survive for up to 35-40 years and even more if taken better care of.
The above features enhance the efficiency of Mono PERC panels by at least 30%. The latest technology in solar power systems makes sure that you get the most out of your solar panels.
