Monocrystalline vs. Polycrystalline Solar Panels


Definition of Solar Panel

Solar panels can be broken down into two categories: thermal and photovoltaic. Solar panels that produce heat by concentrating sunlight are referred to as thermal solar panels. Solar panels that use photovoltaic, or PV, technology collect the sun’s rays and turn them into usable electricity.

Photovoltaic solar panels are generally considered the best option for residential applications. Even though their overall efficiency is lower than that of solar thermal panels, they are better suited for usage on a home scale because they do not require extensive equipment.

One can think of a solar panel as analogous to a picture frame. It is shaped like a rectangle, and a metal frame surrounds it. The front of it is covered in protective glass. A solar panel is composed of multiple layers, the most essential of which is the layer that holds the matrix of solar cells. A solar panel can be broken down into parts per layer.

Each solar panel can include anywhere from 32 to 96 solar cells, and when all of the cells are linked along the panel’s length, it can produce anywhere from 230 to 275 watts of power. The number of solar cells in a solar panel can vary.

Monocrystalline solar cells or polycrystalline solar cells can make up the solar array. Monocrystalline solar cells are used in the more expensive panel because they can capture the sun’s rays more efficiently. However, polycrystalline panels are typically more cost-effective and may be preferable in locations that receive a lot of sunlight.

Comparison of Monocrystalline solar panel vs polycrystalline solar panel is continued under:

Monocrystalline panels

In contrast to polycrystalline solar panels, which employ several silicon crystals for each solar PV cell, only use a single crystal for each PV cell. Individuals could refer to these items as “mono solar panels” in specific locations.

Monocrystalline solar panels can be identified by the dark color of their photovoltaic (PV) cells and rounded corners. Because of how efficiently they transform light into electricity, they produce more electricity that can be utilized in the same amount of time as polycrystalline panels. Because they generate more energy per square foot than other solar panels, monocrystalline panels are the ideal option if you want to install solar panels but don’t have a lot of room. The production method for single-crystal silicon cells is more involved and time-consuming, which is one of the reasons why these solar panels have the highest efficiency ratings and prices.

A solar panel manufactured from monocrystalline solar cells, sometimes known as “wafers,” is referred to as a monocrystalline solar panel. Forming a cylindrical ingot from a single crystal of silicon is the first step in producing monocrystalline wafers. Even though Monocrystalline solar panels are typically regarded as a luxury solar product, the primary benefits of using these panels are higher efficiency and a more streamlined look. Electrons, responsible for the flow of electricity, have more excellent room to move around inside a monocrystalline cell because the cell is made up of a single crystal. As a consequence of this, monocrystalline solar cells, which are the predecessors of polycrystalline solar cells, have higher efficiency. Although you will have to install fewer monocrystalline panels on your roof to generate the same amount of power as you would with other types of panels, the cost of each panel will be higher.

As a consequence of this, monocrystalline solar cells, which are the predecessors of polycrystalline solar cells, have higher efficiency.

Monocrystalline solar panels (or mono panels) are manufactured from monocrystalline solar cells. Each cell is a thin slice cut from a single crystal of silicon produced with the specific intention of being used in producing solar panels.

After being developed into the shape of a cylindrical log, known as an ingot, the crystal is sliced into thin discs in the laboratory. Octagons are formed from each disc by cutting it along its edges to create the shape.

The octagonal forms of the solar panels allow for the maximum amount of solar cells to be packed into the array after the solar cells have been installed on the solar panels. It’s not too dissimilar to placing cookies on a baking sheet. However, octagonal cookies can be packed together with very little wasted space, but round cookies will always have gaps between them, no matter how closely they are spaced.

Monocrystalline solar panels are easily identifiable by their dark color and have an efficiency that generally falls in the range of 15% to 20%. However, some more recent experimental types have reached nearly 50%.


  • Highly effective in terms of the production of energy
  • Panels demand less space
  • Black panels can be easily concealed by darker roof shingles or greenery
  • Higher resistance to the heat


  • Expensive
  • Production practices that aren’t as eco-friendly

Best Applications for Monocrystalline solar panels

  • Smaller applications
  • Places that receive less direct sunshine
  • The level of efficiency achieved is more essential than the cost.
  • How one seems to others is essential.

Since Monocrystalline solar panels generate more electricity on a smaller scale than polycrystalline panels, they are the ideal choice for locations with limited available space. Even in locations with less sunlight, Monocrystalline solar panels are capable of extracting the maximum amount of energy possible. Therefore, they are perfect for situations where effectiveness, rather than cost, is the primary concern.

Even though they are all somewhat cumbersome, Monocrystalline solar panels are better able to blend into their surroundings than polycrystalline panels because of their darker color.

Solar panels made of monocrystalline silicon have a greater capacity for withstanding heat than polycrystalline panels. Because of this, they are an excellent option for locations that experience high levels of heat, such as desert conditions.

Polycrystalline Panels

Polycrystalline solar panels have PV cells made from several shards of silicon crystal fused together during production. Parts are taken apart and then put back together to make the whole. People could also refer to them as “poly panels” or “multi-crystalline panels.”

Polycrystalline material results in blue PV cells with square corners in solar panels. Monocrystalline refers to another name for these panels. Compared to monocrystalline cells, they have a lower efficiency, which implies that you will need additional panels to achieve the same power output level. However, polycrystalline panels, made by a more straightforward process, can be had at a lower cost than their monocrystalline counterparts. Even though they are very long-lasting, polycrystalline panels often have a shorter lifespan than their monocrystalline counterparts. They also produce less on days when temperatures are extremely high since they are more susceptible to heat harm.

Silicon is also used in the production of polycrystalline solar panels. However, rather than employing a single crystal of silicon, producers form the wafers for the panel by fusing several silicon fragments using a melting process. Polycrystalline solar cells have a few different names, including “multi-crystalline” and “many-crystal silicon.”

Solar panels made using polycrystalline cells often have lower efficiency than monocrystalline cell choices. This is because polycrystalline cells include significantly more crystals, which results in less room for electrons to move freely. Because the manufacturing procedure for these panels is more straightforward, they can typically be purchased at a reduced cost. In addition, polycrystalline solar panels typically have a blue hue, as opposed to the dark hue characteristic of Monocrystalline solar panels. However, due to their lesser efficiency compared to other types of solar panels, you will require more of them to power your home, despite their lower price.

Individual polycrystalline solar cells are used to construct polycrystalline solar panels, often known as poly panels.

Polycrystalline solar cells are constructed out of silicon crystals in the same way that monocrystalline solar cells. On the other hand, the silicon crystal is the crucial distinction when it is allowed to cool and fragment on its own rather than being extruded as a single pure ingot. These pieces are melted in an oven, then molded into cubes, and sliced into wafers of a uniform thickness. As a result, this amalgam is composed of various distinct crystals, unlike those in monocrystalline solar cells. Since the manufacturing procedure for polycrystalline cells is less stringent than that for monocrystalline cells, it is possible to create more solar cells in a shorter amount of time and at a lower cost.

There is no free space between the blue square polycrystalline cells since they fit together so tightly side by side. Solar panels made of polycrystalline silicon have a lower efficiency than those made of monocrystalline silicon because the melted silicon shards allow less space for electrons to flow around.

In general, the efficiency rating of polycrystalline panels falls below 13% to 16%. Even though polycrystalline panels have a somewhat lower efficiency than monocrystalline panels, the difference can be significant when multiplied across many solar panels.


  • Less costly than panels made of monocrystalline silicon
  • A life expectancy that is comparable to that of monocrystalline panels but at a more affordable price


  • Panels demand greater room
  • Less efficient at producing energy
  • Less sustainable production
  • The bluish tone is more noticeable than the dark color of the polycrystalline panels
  • Lower tolerance for heat

Best Applications for Polycrystalline Solar Panels

  • A more expansive scope
  • Locations that receive the most sunlight
  • The cost is the primary consideration.
  • The pursuit of beauty is not a top priority

When you need to keep an eye on the bottom line, polycrystalline solar panels are your best option.

Assuming you have room for the panels, polycrystalline units are the more cost-effective option when compared to their monocrystalline counterparts, which typically cost an additional $0.05 per watt.

Polycrystalline solar panels generate less power than Monocrystalline solar panels. Therefore, they are more effective in locations with a lot of sunlight.

When deployed in large numbers in residential locations, the bluish tinge and irregular appearance of something like the polycrystalline panels may not be to everyone’s liking, especially when viewed individually. However, they are most effective when placed in rural locations or urban areas where the panels can be discretely concealed, such as on the roof of a building or in the backyard of a residence.

Which Type of Solar Panels, Monocrystalline or Polycrystalline, Should You Get?

Both types of solar panels have their own set of benefits in addition to their own set of drawbacks, and either one can provide an outstanding return on investment. In any case, to make things easier on yourself, think about the following details while picking the best solar panels for your home:

Is there a preferred shade of solar panels?

Remember that polycrystalline panels are blue, while monocrystalline panels are black. Solar panels are available in various configurations, so you can choose the one that best suits your needs.

In what capacity do you envision solar panels being used?

The manufacturer and the solar panel brand collaborate to determine the precise dimensions required for installation in residential settings. Typically, the dimensions of each panel are 65 inches by 39 inches, which results in a total of 17.6 square feet. On the other hand, amorphous panels produce fewer watts per square foot than their monocrystalline counterparts. The width is typically 65 inches, while the height is typically 39 inches. Using monocrystalline panels allows you to install more kilowatts in a given space, and the following is a simplified example of how this might be done:

You can find that a panel with polycrystalline cells produces only 300 watts, while a panel with monocrystalline cells of the same size produces 350 watts.

Twenty monocrystalline panels will produce 7 kW of power, but twenty polycrystalline panels will produce just 6 kW.

So, how do your financial plan and resources look?

Solar panels made of polycrystalline silicon are often less expensive than those made of monocrystalline silicon. You might be able to afford to have solar panels installed on your home if you can secure financing for solar energy at interest rates that you consider reasonable. You will be able to pay off the loan with the money you save on your monthly electricity bill once the solar panels have been installed and are operational.

In this case, there is no need to be concerned about the additional cost that monocrystalline panels would incur. Also, make sure you compare multiple solar quotes. Individually, Monocrystalline solar panels have a higher price tag, but you also need to consider the additional expenses of other system components and installation. Even if a single panel is higher, the entire cost of a monocrystalline panel installation may be less expensive in some circumstances.

If you were to choose between monocrystalline and polycrystalline solar panels, which would you choose and why?

Solar panels that are monocrystalline and polycrystalline each have their advantages and disadvantages; therefore, the type of solar panel that will work best for your project will be determined by the specifics of your project. Monocrystalline panels are the way to go when space is at a premium and you are willing to make a more significant financial commitment to get the highest possible efficiency level. On the other hand, when you want to lower upfront expenditures and space is not a limitation, polycrystalline solar panels are recommended.

To compare and contrast, what are the characteristics of polycrystalline and Monocrystalline solar panels?

The blue cells that make up polycrystalline solar panels have more than one silicon crystal in each cell. These solar panels have a lower efficiency than Monocrystalline solar panels but are less expensive. Monocrystalline panels are exactly what they sound like: panels made up of cells produced from a single crystal. This indicates that they function more effectively than polycrystalline panels but come at a higher cost.

When comparing monocrystalline and polycrystalline solar panels, what is the pricing range?

The price difference between monocrystalline and polycrystalline solar panels varies according to the type of panels being compared. On the other hand, the difference in cost is frequently indicative of how significantly more or less successful one is. Monocrystalline panels are approximately 20% more efficient than polycrystalline panels, despite being around 20% more expensive.

It is advised that you compare the prices quoted for entire solar power systems because these will include the costs of installing all of the other components of the system.
