Applications of polycrystalline solar panel
It is applied at a residential level, when price is an important factor when making the decision and there are no space problems.
At commercial and industrial levels, it is used in large-scale installations, where a lower installation cost can be a great advantage.
They are also used in large-scale solar energy projects. For example, the panels you see in solar parks are often polycrystalline. And if you look closely, you will notice that their colour is more blue than black, and that the surface is mottled rather than homogeneous.
Difference between monocrystalline sale leads zambia email address and polycrystalline
To help you make your decision about which panels to install in your home or business, we summarize the differences between both types of panels:
Efficiency
Monocrystalline: They can convert between 15% and 22% of the sunlight they capture into energy.
Polycrystalline. Their efficiency is limited to 13%-16%.
Manufacturing
Monocrystalline: These are made from a single crystal of pure silicon that is cut into wafers. This is known as the Czochralski method , which is more expensive and produces more material waste.
Polycrystalline: These are made by melting several crystals of less pure silicon to create a block that is then cut into wafers. This simpler process is cheaper than the previous one and generates less waste.
Appearance
Monocrystalline. Its color is uniform, in a black or dark blue tone. With rounded edges.
Polycrystalline. The color is mottled blue and the edges are rectangular.
Cost
Monocrystalline: Since the manufacturing process is more complex and the silicon used is of high purity, their price is high.
Polycrystalline. The lower complexity of the manufacturing process and the use of lower quality raw materials make the final product cheaper.
Performance
Monocrystalline: They work better in low light conditions and are not as affected by high temperatures.
Polycrystalline. Their efficiency decreases more quickly under high temperature and low light conditions.
The main difference between monocrystalline and polycrystalline is efficiency and performance. This is what justifies why monocrystalline panels are somewhat more expensive than polycrystalline ones.
