Monocrystalline versus polycrystalline
Both monocrystalline and polycrystalline solar panels have benefits and drawbacks, so which should you choose? To discover the answer, you must first understand how they operate and what services they provide.
Here, I’ll go through both of their benefits as well as the best items in each category:
Monocrystalline solar panels
Monocrystalline solar panels are made from a single piece of crystalline silicon ingot and are the most solid. They are easily identified by their unique diamond-cut design on a dark black panel.
With pure silicon in them, monocrystalline solar panels are the most efficient choice since they can better use the sun’s irradiation. These solar panels are more expensive than others since they are made entirely of silicone and do not contain any other ingredients.
However, you’ll get a much longer life expectancy with them than you would with a 25-year warranty.
Using monocrystalline solar panels, despite their higher cost, might result in a large increase in turn. If you use monocrystalline solar panels, the following are the primary advantages you can expect:
- Because of their pure silicone construction, monocrystalline solar panels are the most efficient solar panel solution compared to other types of panels.
- These panels require less space to install than the others since they capture more sun irradiation and produce more power with less installation.
- Monocrystalline solar panels have a far higher life expectancy than other types, and they come with a 25-year warranty.
- Monocrystalline solar panels can function effectively even in low-light conditions and collect energy in a shorter amount of time.
- No matter how windy or dark the day is, these solar panels may drastically lower your electric expenses by producing high energy.
Renogy 100 Watts 12 Volts Monocrystalline Solar Panel
Renogy has encapsulated extremely effective pure silicon solar cells in their monocrystalline solar panel for longer, more efficient performance. For optimal rigidity, the cells are coated with an EVA layer and topped with durable low-iron tempered glass.
On the back of the cells is a TPT back sheet, as well as a pre-attached junction box with MC4 connectors. Because the panels and connectors are entirely waterproof and rigid, you can use the panel outside in an RV, boat, tent, or roofing.
This panel is surrounded by a heavy-duty hard-anodized aluminum frame with pre-drilled mounting holes and drainage holes. Although it is a small panel (47” x 21.3”), it can produce up to 100 watts at 12 volts, making it the greatest 100-watt solar panel.
- With 12 Volts, this monocrystalline panel may produce up to 100 watts.
- The cells are topped with EVA film and low-iron, transparent tempered glass.
- The solar cells are protected from the back by a TPT back sheet.
- Because the junction box is IP67 weatherproof, you can use the panel outside in an RV or boat.
- It has a hard-anodized aluminum frame that prevents corrosion.
Polycrystalline solar panels
Polycrystalline solar panels contain silicon as well, but they also contain a variety of other materials. Unlike monocrystalline panels, the building components are melted and poured into a square mold.
They go through a slicing process to square savers that you can see on the polycrystalline solar panels after the mold is cool. They are distinguishable because, unlike monocrystalline panels, they do not have a diamond cut to shape.
Instead of dark black, they usually come in blue and may have a variety of aesthetic designs.
- Using polycrystalline solar panels has a number of benefits, including improved overall aesthetics. The following are the primary advantages of adopting polycrystalline solar panels:
- Polycrystalline panels are less expensive per panel than monocrystalline panels due to their composite structure.
- Polycrystalline panels are more durable and have a 25-year life duration compared to monocrystalline panels.
- When compared to monocrystalline panels, polycrystalline panels have a reduced electric bill in the long run.
- In terms of the environment, polycrystalline solar panels are effective at reducing greenhouse gas emissions.
- When snow, mud, shade, or other barriers cover the solar circuits of polycrystalline panels, they do not quickly break down.
Newpowa 100 Watts 12 Volts Polycrystalline Solar Panel
Newpowa’s polycrystalline panel features a smaller cell architecture but is still capable of producing 100 watts at 12 volts. It can power a tiny house or RV due to its high efficiency in production from a small form factor.
To maximize performance, all of the cell panels are encased with ethyne vinyl acetate (EVA). They also have entirely clear, low-iron tempered glass on the front for maximum weatherproofing, making them the ideal solar panels for boats.
A strong Tedlar polyester Tedlar (TPT) sheet is attached to the rear of the panels for added stability. Its panel cells include a heavy-duty chassis with anodized aluminum that maximizes the panel’s rigidity, in addition to the hefty construction.
- With a voltage of 12 volts, this polycrystalline solar panel can produce 100 watts.
- It includes a junction box with pre-installed diodes and three 3-foot MC4 cables.
- For further durability, the solar panel cells are encased in a robust anodized aluminum frame.
- The solar cells are made of ethylene-vinyl acetate, which is a strong material (EVA).
- Its front panels are made of transparent tempered glass, while the back panels are made of TPT for weather protection.
Let’s break it down!
Now that you understand the differences between monocrystalline and polycrystalline solar panels let’s look at how each type of solar panel performs. The key differences between monocrystalline and polycrystalline solar panels are summarized in the table below:
|Factor||Monocrystalline Solar Panels||Polycrystalline Solar Panels|
|Silicone Arrangement||One pure silicon crystal||Many silicon fragments melded together|
|Look||Panels have a black hue||Panels have a blue hue|
|Efficiency||Higher efficiency||Lower efficiency|
|Longevity||25-40 years||20-35 years|
|Temperature Coefficient||Lower temperature coefficient, thus, higher efficiency in heat||Higher temperature coefficient, thus, less efficiency in heat|
Because pure silicon ingots are circular, splitting them produces square wafers with rounded edges, resulting in minimal gaps between cells when constructed. Since they are formed of pure silicon, they have a consistent black appearance due to the way light interacts with pure silicon.
Monocrystalline solar cells are easily identified by their uniform dark color and rounded edges squares with small intervals between each cell. Don’t worry; even though the monocrystalline solar cell is dark, the back sheets and frames come in a variety of colors and styles to suit your tastes.
Polycrystalline solar panels
Polycrystalline solar cells, in contrast to monocrystalline solar cells, exhibit a blue color due to the way sunlight interacts with the multi-crystalline. Polycrystalline wafers do not have rounded edges since they are not carved from cylinders like monocrystalline wafers.
As a result, their bluish color and lack of rounded edges make them easy to spot. Polycrystalline cells also come in a variety of vibrant back sheets and frame patterns to complement your roof.
The key component that impacts cost is the silicon structure of each solar panel. Manufacturers can make polycrystalline panels by pouring molten silicon into square molds and then cutting the resulting wafers into individual cells.
To make single-crystal solar cells, on the other hand, the solidification of silicon must be precisely controlled. Mono panels are more expensive due to the more complicated manufacturing process.
Here are a few factors to bear in mind when it comes to solar panel prices:
- When comparing merely the panels, monocrystalline solar panels are more expensive.
- Both solar panel types have the same cost of inverters, wiring, electrical protections, racking, and labor.
- You may obtain a higher return on your investment with monocrystalline panels because they are more efficient.
- Whether homeowners choose mono or poly panels, they are qualified for the federal solar tax credit.
Temperature coefficient and efficiency
Monocrystalline solar panels, as previously said, offer greater efficiency. This isn’t to say that polycrystalline solar panels aren’t good; there are high-quality polycrystalline solar panels available. Here are a few more efficiency statistics:
- A higher-efficiency solar panel transforms a greater percentage of sunlight into electricity.
- Polycrystalline panels have typical efficiencies of 20% as of 2021, whereas the best monocrystalline panels have efficiencies nearing 23%.
- Because polycrystalline panels have lower efficiency, you’ll need more of them to obtain a certain monthly kilowatt-hour output.
- When the temperature of a solar panel rises, its efficiency drops temporarily, but monocrystalline solar cells are less affected.
The temperature coefficient shows how much temperature affects solar panels. To ensure a fair comparison, all solar panels are factory-tested under the same Standard Test Conditions (STC).
Polycrystalline solar panels have greater temperature coefficients than monocrystalline solar panels, which means they lose more productivity as they heat up.
However, as technology advances, both types of solar panels now have temperature coefficients that are similar.
When you have plenty of room, solar panel efficiency isn’t a major consideration. Installing more polycrystalline panels to compensate for the lower efficiency is not a problem because they are less expensive.
Installing more panels is not an option when space is restricted. Thus monocrystalline panels will maximize electricity generation in the existing space.
Both types of solar panels have a long lifespan and, in many circumstances, a payback period of fewer than five years. Solar manufacturers typically provide a 25-year warranty on electricity production, although some brands now provide a 30-year warranty.
Is it possible to recycle monocrystalline solar panels?
Monocrystalline solar cells can be recycled in a nutshell. The three major components of monocrystalline solar panels are:
- Monocrystalline cells: Approximately 85% of silicon wafers are recycled.
- Glass: Almost all of the glass can be recycled.
- Metal: All metal components are 100% recyclable.
Is it possible to recycle polycrystalline solar panels?
Around 90% of the material needed to make polycrystalline cells is recyclable, much like monocrystalline cells. By 2030, it is estimated that about 45 million new modules will be built using recycled materials, equating to 380 million dollars.
Is it better to use monocrystalline or polycrystalline solar panels?
Each form of solar panel has benefits and drawbacks, and both can provide a good return on investment. Consider the following factors when choosing the best solar panels for your home to make your decision easier:
Do you have a certain color in mind for your solar panels?
It’s important to remember that monocrystalline panels are black and polycrystalline panels are blue. You can acquire solar panels to fit your preferences if you prefer one over the other.
How much room do you have in your home for solar panels?
Solar panels for the home come in a variety of sizes, depending on the brand and manufacturer. The normal panel size is 65 inches by 39 inches or 17.6 square feet.
However, monocrystalline panels provide more watts per square foot. Here’s an example of how monocrystalline panels might let you install more kilowatts in a smaller space:
- A polycrystalline panel may yield 300W, while a monocrystalline panel of comparable size produces 350W.
- If you have enough space for 20 of them, the monocrystalline panels will produce 7 kW, but the polycrystalline panels would only produce 6 kW.
What are your financial and budgetary options?
Although polycrystalline solar panels are less expensive, monocrystalline panels are more efficient. You can finance your solar installation and pay off the loan with the money you save on utility bills if you have access to a solar loan with a low-interest rate.
The higher cost of monocrystalline panels isn’t a concern in this scenario.
Make careful to compare several solar quotes as well. Individually, monocrystalline solar panels are more expensive, but other system components and installation expenses must also be considered.
Even if a single monocrystalline panel costs more, a complete installation with monocrystalline panels may be less expensive.
So which one should I use?
Before purchasing a solar panel, you must take into account a number of factors. The Monocrystalline panel is recommended if you plan to use the panel frequently outside or install it on your RV roof or boat.
It boasts an IP67 waterproofing rating, as well as a robust hard-anodized aluminum frame to keep it safe. If you don’t need the panel right away or have a smaller project in mind, the Polycrystalline solar panel is a good option.
Although the panel and junction box are both waterproof, there is no rating for them, which is crucial for consumers to realize.
Here are some of the most common questions concerning both solar panels and what you should know about them:
When it comes to monocrystalline solar panels, how long do they last?
Monocrystalline solar panels have a warranty of at least 25 years from the leading manufacturers.
Is it possible to combine polycrystalline and monocrystalline materials?
Yes, you can combine the two panels; for the greatest results, use an MPPT controller.
How long do solar panels typically last?
With the proper installation, both poly and mono solar panels can last up to 25 years.
Selecting the right solar panel becomes easier now that you have all the information about monocrystalline vs. polycrystalline solar panels. I hope you’ve chosen the best solar panel unit for your needs after going over the specifications.
If you’re still undecided and want a professional recommendation, I recommend the Monocrystalline panel.
The junction box and connectors have the highest possible waterproofing grade of IP67. The front of the cells has a transparent tempered glass weather resistance and protection, while the rear has TPT.
With its strong structure and hard-anodized frame, it may be used in any setting for decades, from an RV to a boat to a house roof.
