When you think about switching to solar, the first thing that strikes your mind is selecting the correct solar panel module. With numerous options in the market, the choice can become overwhelming. However, you will find two main types of panels: Monocrystalline and Polycrystalline.
Although both panels perform similar work, they have differences that make one better than another. To help you understand the differences and determine which one is more suitable to your requirements, we have prepared this blog covering all the differences between monocrystalline solar panels and polycrystalline solar panels.
A monocrystalline solar panel is a PV module prepared using monocrystalline wafers or solar cells. Each wafer consists of a single silicon crystal cut out from a cylindrical log shape, also known as an ingot. These crystals are specially grown in the lab and fitted on solar panels tightly in an octagonal shape, ensuring less wasted space.
Moreover, the single-crystal composition allows electrons more space to move, making them more efficient than polycrystalline solar panels. So you will need fewer monocrystalline panels on your roof to generate more kWh of energy. These are some of the advantages of monocrystalline PV modules that make them a top choice.
A polycrystalline solar panel is a solar module prepared using multiple silicon crystals. The process involves melting numerous silicon fragments to form wafers fitted in panels. Due to this, it is often called multi-crystalline.
Polycrystalline solar panels can be easily recognised because of their blue hue with straight edges. The easy manufacturing process adds to their lower pricing.
However, multiple silicon crystals usage in polycrystalline modules doesn’t offer electrons much space to move, reducing their efficiency. So you will need more panels to generate the required amount of electricity.
Now that we have understood the basics of both modules. Let’s compare monocrystalline vs polycrystalline solar panels and explore the key factors that distinguish one system from another.
One of the key differences between the two panels is their aesthetics. The construction of both panels adds to their unique appearance. While monocrystalline PV modules have a single silicon crystal that gives them black colour, polycrystalline has a blue hue due to the formation of many silicon crystals because of improper alignment of silicons in manufacturing.
Moreover, the rounded edges of monocrystalline panels give them a sleek and uniform appearance, adding to the aesthetics of residential and commercial properties. In comparison, polycrystalline has straight edges, making them look more fragmented.
When you compare a polycrystalline vs monocrystalline price, polycrystalline looks like a cheaper option. But it doesn’t mean being expensive makes monocrystalline panels a better choice for everyone. That’s because the cost of these PV modules relies on their silicon structure. For preparing the polycrystalline modules, manufacturers pour molten silicon into square moulds. Later these set wafers are cut into individual cells and placed in a panel.
In comparison, monocrystalline panels follow a more complex process, requiring the solidification of silicon must be controlled very carefully, which makes them more expensive.
Although monocrystalline PV modules are expensive, this price factor only limits the panel itself. When you consider other elements like inverters, electrical protections, waiting, racking or labour cost, the price is similar for both. You can even benefit from federal solar tax credit with both systems. However, monocrystalline panels offer better efficiency even with limited space. So you will get a better return on investment.
A solar panel’s quality relies on how efficiently it can convert sunlight into electricity. It means the higher the efficiency, the higher the percentage of solar power it will turn into usable energy.
Monocrystalline solar panels win over polycrystalline in efficiency because they consist of a single silicon crystal that allows more space for electricity to travel throughout the solar panel.
As of 2021, monocrystalline panels have the highest efficiency of around 23%, while polycrystalline module efficiency can only reach below 20%. However, this doesn’t mean you can’t get high efficiency in polycrystalline panels. Since its price is lower, you can add more modules to reach the appropriate amount of power.
The temperature coefficient factor of a panel indicates how much its performance gets affected by temperature. So when you compare monocrystalline vs polycrystalline solar panels on this basis, monocrystalline outperforms polycrystalline models. It means if you have a polycrystalline solar panel, it may work a little less efficiently when the temperature gets very high.
Both monocrystalline and polycrystalline are the top solar panels available in the market. However, the entire choice relies on you.
If you want a panel that will add to the aesthetic value of your property, monocrystalline solar modules work perfectly with their sleek appearance. And if you have a colour preference, you can choose between dark black monocrystalline modules or polycrystalline with a blue hue.
Although monocrystalline panels look more expensive due to the higher price tag, they also offer higher efficiency, longevity, and a sleek appearance. On the contrary, polycrystalline panels are more affordable upfront but may require more space and have slightly lower efficiency.
If you have limited roof space but need to maximise energy production, then monocrystalline panels can work better with their higher efficiency. However, if you have ample space but want something under budget, you can opt for polycrystalline panels.
We hope all the differences discussed in this blog helped you distinguish between both types of panels. Although the features and benefits of monocrystalline PV modules overpowers polycrystalline, the choice depends on your needs and budget.
