Which Solar Panel Should You Choose

 

If you are reading this article, it means you have already decided to “go solar”. It is definitely a laudable decision because as the technology is maturing its prices are declining and efficiencies are improving. When you make up your mind to buy a solar panel, you will encounter two choices primarily - mono or polycrystalline. The third type is thin film technology. As a layman it becomes difficult to understand the difference between these two technologies. So let’s have a brief understanding about the two:

 

Monocrystalline Solar Panel Technology

 

During polysilicon manufacturing, it is possible to grow pure silicon made of a single crystal. The solar panels made out of this single crystal of pure silicon is called monocrystalline solar panel. They are made out of the highest-grade silicon. Since they are made out of the highest-grade silicon, the efficiency of monocrystalline solar cells is high and range in between 18% to 24%. These are black in colour and have a uniform look. Mono solar panels price in India is generally higher when compared to multicrystalline solar panels.

 

Multicrystalline Solar Panel Technology

 

Multicrystalline solar panel technology is the more prevalent technology in the world. These solar panels are made out of polycrystalline silicon which can be as much as 99.9999% pure. These panels have an efficiency of between 13%-17%. Multicrystalline solar cells have lower efficiency and costs than monocrystalline solar cells. But that is changing over time and today few brands of multicrystalline solar panels are offering efficiency levels of 20%+. These are blue in colour but not very uniform in appearance.

 

Difference in Polycrystalline and Monocrystalline Solar Panels

 

 

While both mono and multicrystalline work on the same principle of capturing solar energy and both will go a long way in reducing your electricity bills, there are few basic differences between the two. These differences will help you to identify monocrystalline and polycrystalline solar panels.

 

Criteria

Mono Crystalline panels

Poly Crystalline panels

Efficiency

High efficiency 17-20%

Less efficiency 13-16 %

Design & Looks

Made of single silicon cells – all cells are black in color

Made of multiple silicon cells – looks  blueish in color

Space

Occupies less rooftop space

Takes more space

Performance

Performs better even in low light

Low efficiency in cloudy weather

Price

Expensive

Relatively low price

 

Monocrystalline vs. Polycrystalline Solar Panel: Which is right for you?

This is the most common query of buyers. No one technology is superior or inferior than the other. Both of these panels generally have a 25-year warranty. The type of solar panel you choose should depend upon your needs and location. For example, monocrystalline solar panels perform better even in low light conditions. In fact these panels are more effective in warm weather conditions. So if you stay in a less hot region, you might want to choose monocrystalline solar for your power needs. On the contrary, if you have a lower budget or if you do not have space constraint you would want to select multicrystalline solar technology.
