How Do Solar Panels Work?

Before delving into a detailed understanding of the types of solar panels, it might be helpful to grasp the basic workings of solar panels. Solar panels are composed of photovoltaic cells made of silicon. When sunlight strikes the surface of the panels, they generate an electric current, creating an electric field. The resulting current is then directed to a charge controller, which regulates how much current is sent to the battery or inverter for use with different appliances.

Difference Between Monocrystalline and Polycrystalline Solar Panels

What is a Monocrystalline Solar Panel?

Monocrystalline solar panels are made of a single silicon crystal cell that is formed into a crystalline silicon ingot. They are dark in color and are best known for their superior efficiency compared to other types of panels. Monocrystalline solar panels, being composed of a single crystal, provide more room for electrons to move, resulting in higher efficiency and requiring fewer panels to generate the same amount of electricity compared to polycrystalline solar panels.

These panels have a uniform black color and a sleek appearance, making them a popular choice for domestic and commercial installations. Although these panels are considered premium-quality solar panels, they come at a higher price.

What is Polycrystalline Solar Panel?

Like monocrystalline solar panels, this type of solar panel is also made of photovoltaic cells. However, manufacturers of these panels melt multiple fragments of silicon together to form the wafer for the panel. They are also known as multi-crystalline or many-crystalline silicon. Polycrystalline solar panels are blue in color and have lower efficiency compared to monocrystalline solar panels, as there are multiple crystals in each cell, resulting in less space for electrons to move. Nevertheless, they remain a popular choice for many domestic and commercial installations. They are generally less expensive than monocrystalline solar panels, making them a good option for installations with larger roof spaces.

How Do Monocrystalline and Polycrystalline Solar Panels Compare on Key Metrics?

There are significant differences between monocrystalline and polycrystalline solar panels in key areas such as cost, efficiency, lifespan, and more. Let’s explore how these two panels compare to each other in a few areas.

Key MetricsMonocrystallinePolycrystalline

Both monocrystalline and polycrystalline solar panels may appear similar, but the primary difference between monocrystalline and monocrystalline solar panels lies in their aesthetic colour. Monocrystalline panels are dark grey, resembling almost black, while polycrystalline solar panels are light blue in colour.


When comparing the cost difference between monocrystalline and polycrystalline solar panels, it is evident that monocrystalline panels are more expensive due to their higher efficiency. However, this does not mean that polycrystalline solar panels are not a viable option for a solar system. Both types of panels serve the same purpose, with the main difference lying in the silicon structure. While monocrystalline panels come at a higher cost, it’s important to consider that other components required for solar system installation, such as inverters, wires, electrical protections, mounting structures, and labour costs, remain the same regardless of the panel type.


When comparing the lifespan of monocrystalline and polycrystalline solar panels, both types typically come with a 25-year warranty and often last even longer. However, if you have limited space available for solar panel installation, opting for monocrystalline panels may offer a better return on investment.


There is no doubt that monocrystalline solar panels are more efficient than polycrystalline solar panels because they are cut from a single crystal of silicon. Monocrystalline solar panels can achieve efficiencies of over 23%, while polycrystalline panels typically remain below 20%.

Temperature Coefficient 

Monocrystalline panels are more temperature resistance, they perform well in the changing temperature while the polycrystalline solar panels are less efficient in the changing temperature.

So Which Solara Panel should I Purchase?

The decision of choosing a solar panel can depend on various factors, including cost, available space for installation, and design. Let’s explore each of these factors individually.

How Much Can You Spend on Solar Panels?

Cost is the primary factor that can influence the decision of purchasing a solar panel. It depends on how much you are willing to spend on the solar panel. If price is not a concern and you prioritize quality, then monocrystalline solar panels are the ideal choice. They offer higher efficiency and attractive design. On the other hand, if you have a limited budget for solar panel purchase, polycrystalline panels are a cost-effective option. Despite being lower in price, they still perform well in warm temperatures and have an efficiency rate of up to 20%.

Space Constraint

If your roof has limited space, the best option is to choose higher efficiency solar panels. Monocrystalline solar panels are the preferred choice for such buildings due to their higher efficiency rate while occupying less space. On the other hand, if you have ample space or plan to install ground-mounted solar panels, the best economical option would be lower efficiency solar panels, specifically polycrystalline solar panels.

Personal Preference

It all depends on your preference. If you are conscious about the color and design of the solar panels and how they will appear on your roof, there is a difference between monocrystalline and polycrystalline solar panels colors. Monocrystalline solar panels typically have a dark grey color, while polycrystalline panels come in a shade of blue.

Where Can I Buy Monocrystalline and Polycrystalline Solar Panels.
