When choosing solar panels for your photovoltaic (PV) system, you’ll encounter monocrystalline and polycrystalline panels. Both types are powered by the sun, but there are key variances. Om Solar Solutions knows how crucial it is to choose the right solar energy company when rooftop solar panels installation. Since installing solar panels is becoming more popular, homeowners compare monocrystalline and polycrystalline solar panels. Your solar system’s performance, cost, and lifespan depend on the type you choose. This tutorial examines each type in detail to help you choose the best for your home.
Key takeaways
- Monocrystalline solar panels are usually more efficient due to their black, single-grain silicon solar cells. However, these screens can cost more.
- Several melting silicon crystals make polycrystalline solar panels’ blue cells. These panels are inexpensive but usually less effective.
- No matter the type of solar panels, homeowners can earn the government solar tax credit.
- Comparisons of mono and poly solar panels show power savings. What you desire, how much space you have, and how to pay determine the choice.

What are monocrystalline and polycrystalline solar panels?
In simple terms, both monocrystalline and polycrystalline solar panels do the same thing: they take energy from the sun (solar energy) and turn it into electricity. They’re both made of silicon, and many solar panel companies make both types.
Both monocrystalline and polycrystalline solar panels can be good choices for your home, but there are some important differences you should know about before making your choice. They differ mostly in silicon solar cell type:
On the other hand, polycrystalline solar panels use solar cells made from many silicon pieces that have been melted together. Monocrystalline solar panels use solar cells made from a single crystal.
Monocrystalline solar panels
It has monocrystalline solar cells, or “wafers.” Monocrystalline wafers are manufactured from a single grain of silicon that has been formed into a cylinder. Monocrystalline panels may seem like high-end solar equipment, but they operate and look better.
Monocrystalline cells have one crystal, giving energy-flowing electrons more space. Thus, monocrystalline solar cells outperform polycrystalline ones. Each monocrystalline panel costs more but requires fewer roof panels to generate more kWh.
Monocrystalline cells have one crystal, giving energy-flowing electrons more space. Thus, monocrystalline solar cells outperform polycrystalline ones.
Key Points of Monocrystalline Panels:
- Purer because it’s created from one silicon cell.
- Allow electrons to move freely to boost performance.
- The same electricity is generated with less panels.
- Use a sleek black style to make things look better.
- Each panel usually costs more than polycrystalline.
Polycrystalline solar panels
Silicon is also used to make solar screens with lots of crystals. But makers don’t use a single crystal of silicon. Instead, they melt together a lot of small pieces of silicon to make wafers for the panel. There are a few different names for polycrystalline silicon, including “multi-crystalline” or “many-crystal silicon.”
Most of the time, polycrystalline solar panels are less efficient than monocrystalline cell choices. This is because each cell has many more crystals, which makes it harder for the electrons to move around. The price of these panels is usually lower because they are easy to make.
Additionally, polycrystalline solar panels are blue rather than black. While these panels come at a lower price point, you’ll require a greater number to effectively power your home due to their reduced efficiency.
Key Points of Polycrystalline Panels:
- Production is easy and cheap because it uses many little silicon components.
- It’s better to offer less energy since electrons are less free.
- For monocrystalline panels’ energy output, you need additional panels.
- Feature a blue color, separating them visually from black monocrystalline panels.
- Budget-conscious folks should choose these because they cost less per panel.

Monocrystalline vs. Polycrystalline: Key Differences Explained
Everything revolves around the stats. Listed below are some of the important areas in which monocrystalline and polycrystalline solar panels compare and contrast with one another:
| Metric | Monocrystalline Panels | Polycrystalline Panels |
| Cost | More expensive | Less expensive |
| Efficiency | More efficient | Less efficient |
| Appearance | Black hue | Blue-ish hue |
| Lifespan | 25+ years | 25+ years |
| Temperature Performance | Lower coefficient, more effective as temperature changes | Higher coefficient, less effective as temperature changes |
- Cost: Based on how they look, monocrystalline solar panels cost more than polycrystalline ones. You might find that they are a terrific match for you. The silicon structure is what makes these two solar panels distinct in price. Manufacturing polycrystalline screens involves pouring molten silicon into square molds and cutting wafers into cells. It’s harder to keep track of silicon solidification in monocrystalline panels. Because of this, single-crystal solar cells cost more.
- Monocrystalline panels cost more. However, inverters, wiring, electrical protections, racks, and work cost the same. If you have limited space for solar panels, monocrystalline panels may offer a superior return on investment. Don’t forget that the government solar tax credit can be used for both types of solar panels.
- Efficiency: Most of the time, monocrystalline solar panels work better than polycrystalline panels. They are easy for the most electricity to run through because they are made from a single crystal of silicon. There are some monocrystalline panels that can get over 23% efficiency, while most polycrystalline panels are less than 20%.
- Aesthetics: The main difference between the two types of solar panels in terms of how they look is their color. Monocrystalline panels are generally black, while polycrystalline panels can look blue.
- Lifespan: Solar panels usually don’t last longer or shorter depending on the type of silicon cell that makes them up. Monocrystalline and polycrystalline panels will both work well for at least 25 years to make power.
- Temperature coefficient: Similar to how efficient they are, monocrystalline solar panels tend to do better than polycrystalline ones when it comes to temperature coefficient. The better a panel’s temperature coefficient is, the better it works in warm temperatures. Since numbers closer to zero are better, it stands to reason that monocrystalline solar panels work better in hot weather.
Choosing The Right Solar Panel: Monocrystalline Vs. Polycrystalline
One of the best reasons to go solar is to save money. Your power bills will go down whether you choose mono or poly solar panels. Your choice will rely on your personal preferences, the amount of space you have, and your available financing options.
- Personal preferences: Monocrystalline and polycrystalline solar panels look different on your roof, so keep that in mind if the color of your panels is important to you. It is common for mono solar panels to be very dark black, while blue polycrystalline panels are more common. Also, if where your panels came from is important to you, make sure you know enough about the company that makes them.
- Space limitations: Solar panels that utilize less energy are beneficial if roof space limits PV system size. This also applies to RVs and tiny equipment that require little space or power. Paying more for monocrystalline panels that are more efficient and maximize system power will pay off in the long term. If you have a large roof or are establishing a ground-mounted solar power plant, polycrystalline panels may be cheaper.
- Solar Financing: Your panel choice may depend on how you expect to pay for your system. A Power Purchase Agreement (PPA) charges per kilowatt-hour for system energy. Therefore, your monthly payments, not the equipment you’re given, will determine your savings. However, if you buy your system all at once, investing in more efficient monocrystalline solar cells may yield a better return.
