Comparison between Monocrystalline & Polycrystalline Solar Panels

monocrystalline vs polycrystalline solar panels

The solar energy industry has continued to grow because companies are consistently testing new technology. The resulting success brings about highly efficient solar panels. The primary types of solar panels for residential areas are monocrystalline or polycrystalline. Thin-film modules are ideal for commercial use.

The existence of these categories can be confusing to anyone new in the solar market. However, this should not be a hindrance in making an informed choice. We have dedicated this article to help you make the best decision when purchasing your solar panels. Let’s begin.

Monocrystalline or Polycrystalline Solar Panels?

monocrystalline solar panels

Both monocrystalline (mono) and polycrystalline (poly) solar panels produce electricity from the sun, and they are made from silicon. Silicon is the most common element used to make solar panels as it is readily available and durable. You will find that most companies manufacture both polycrystalline and monocrystalline panels.

In as much as they may be different, they both make great solar panels for residential use. However, there are differences between monocrystalline and polycrystalline solar panels. The critical difference is the technology in use. The monocrystalline cell comprises a single silicon crystal, while polycrystalline have several melted silicon fragments.

Monocrystalline Solar Panels

If you want a premium product, monocrystalline solar panels are the way to go. They are sleeker in design and have improved efficiency.

To make this product, manufacturers form silicon into bars and cut it into wafers. The single-crystal silicon used gives them the monocrystalline name. Using a single crystal to make the cell provides more room to move to the electrons that generate electricity, a factor that increases their efficiency.

Polycrystalline Solar Panels

The price for these panels is relatively lower though they have reduced efficiency compared to other PV modules. They also come in a blue hue.

To make these photovoltaic modules, manufacturers melt fragments of silicon together, forming wafers for the panels. The panels can also be referred to as many crystals or multi-crystalline silicon. The presence of many crystals in the cells reduces the electrons’ freedom of movement. For this reason, the panels have a lower efficiency.

While choosing between these two types of technology, there are various parameters that you can consider. These are:


As discussed above, monocrystalline solar panels are highly efficient than polycrystalline panels. The super grade silicon used to make the modules puts them in a premium category. The single-crystal structure also contributes to this efficiency as there is minimal resistance in the cells. The polycrystalline solar panels have a low efficiency of about 14 and 16 percent due to reduced silicon purity. 


The first thing that people mostly look at when making a purchase is the cost. Polycrystalline solar panels come at a lower cost than monocrystalline solar panels. You should carefully evaluate monocrystalline and polycrystalline solar panels price to make the right choice.

Temperature Coeffient

One factor that affects solar panels’ performance is the weather. Monocrystalline solar panels have a higher efficiency due to their hot weather coefficient. The panels have a lower output degradation as the temperature increases than polycrystalline solar panels. If you are in an area that is hot for long, this is an essential factor to consider when buying solar panels.


Generally, solar panels have a long lifespan. However, monocrystalline solar panels come with a longer lifespan, and the manufacturers offer a warranty of about 25 years. Polycrystalline panels still have a long warranty but shorter than monocrystalline solar panels.


Most homes have a sense of style and are artfully designed. For this reason, the type of solar panels you choose to install can affect this design. The monocrystalline solar panels get the preference from most users when it comes to design as they are more desirable. The polycrystalline panels come in a blue hue, which may not be the best option.

Choosing between Monocrystalline and Polycrystalline Solar Panels

Once you review the pros and cons of monocrystalline vs. polycrystalline solar panels, you can look at other factors to help you make a decision. Such factors include:


Both types of solar panels will work well for any building, assuming you have enough space. However, when you have an issue with space and your priority is to generate a lot of electricity, monocrystalline is the best option. With limited space, you can’t make the solar energy system large enough. You need maximum production with the available space.

Performance Preference

The product’s parameters can guide you when you are choosing a solar panel. However, personal preference can affect your decision also in the long run. For example, if your roof’s color matters to you, you may find yourself going for monocrystalline solar panels.

Availability of Shade, Dust or Shade

When exposed to snow or dust, the monocrystalline solar panel systems can breakdown. The same also happens under exposure to shade or dust. However, polycrystalline solar panels are resilient enough to withstand these conditions.

As a consumer, if you live in areas prone to snow or dusty, you may choose the more resilient type. The same applies if your roof is partially shaded. However, if you still prefer monocrystalline solar panels, you can install a micro-inverter to solve the problem.

You deserve to get the best solar technology for your home. Monocrystalline or polycrystalline solar panels offer you this option. You can compare their advantages and disadvantages. Additionally, you evaluate their unique features and suitability for you. Remember, when it comes to selecting panels, choosing a good brand is vital. High reputation brands always offer their clients long-term warranties.
