Worst Appearance: Polycrystalline Panels
Polycrystalline panels tend to stick out like a sore thumb. The process in which polycrystalline solar cells are manufactured causes the cells to have a blue, marbled look. This means each individual polycrystalline panel looks substantially different from the one next to it. Most homeowners arent too keen on the aesthetics of polycrystalline panels.
Fun fact! Crystalline panels are more durable than thin film
Thin film panels tend to have lower wind and hail ratings than mono and polycrystalline panels. So, while thin film panels might look nice at first, one bad storm could cause significant damage.
Best Applications For Monocrystalline Solar Panels
- Smaller applications
- Efficiency, not cost, is more important
- Appearance is an issue
Monocrystalline solar panels are best for areas where space is limited since they produce more electricity on a smaller scale than poly panels. Monocrystalline solar panels can draw out the maximum amount of energy even in areas of lower sunlight. So, they are ideal when the goal is efficiency more than cost.
Though all solar panels are bulky, monocrystalline solar panels, with their dark hue, fade into the background better than poly units.
Monocrystalline solar panels tend to have better heat tolerance than polycrystalline panels. So, they are a good choice for areas of extreme heat, such as desert environments.
What Are The Financing Options What Are The Differences Between Them
The best monocrystalline solar panels or the best polycrystalline solar panels may not sometimes fit in your budget. You may need to compare brands and their respective prices before making your choice. Installing solar panels will require an initial investment and there are solar loans available. There are also solar leasing options.
Solar Loans
If your monthly savings on electricity bills is going to be greater than the monthly loan repayment, solar loans will be a good choice. Solar loans will offer a similar structure as in your home improvement loans. You may also have access to subsidized solar loans in certain parts of the country with low-interest rates. Buying your solar panel system outright may get you certain incentives and tax breaks.
Solar Lease or Power Purchase Agreement
You can choose solar or power purchase leases which is similar to renting the solar system. The third-party owner of the solar panel system will accept a below-market rate for the duration. A lease or power purchase agreement can help you save up to 30% each month on your electricity bills and there wont be any upfront cost involved. The third-party owner is also responsible for the maintenance. At the end of the lease period, you may have the option to purchase it at market price or have them remove it from your property.

Monocrystalline Vs Polycrystalline: Which One Is The Best Choice
Monocrystalline and polycrystalline are two popular options of solar panels available on the market today. Both solar panels produce energy from the sun, and for the most part, theyre made from pretty much the same materials.
So, which option should you choose between these two when youre shopping? These solar panels have some key differences that you should know when making a purchase decision.
In this article, youre going to understand the critical differences between monocrystalline and polycrystalline solar panels.
Please read this until the end if youre looking to install a solar panel system that will match your needs!
Which Solar Panel Is Better And Which Is Right For You
As we look above, each type has some advantages and disadvantages. We can use both panels for most purposes. But selecting the right one might sometimes be confusing, so below are some points that will help in deciding what is better and when.
Polycrystalline solar panels are cheaper but less efficient. Their less efficiency does not mean that they are not a good option. In fact, many times, polycrystalline is a wiser choice. Besides being more affordable, polycrystalline, on decent sunny days, provides significant solar power. We can overcome the low efficiency by installing more panels however, more panels might increase the cost of other components of photovoltaic systems. Of course, more panels will require more open space. So, if your property has enough open roof space or ground space, polycrystalline panels will be a better and cost-effective option.
Monocrystalline solar panels perform better than polycrystalline. They are also more efficient, however expensive. Having more efficiency implies they will generate more power than the same size polycrystalline. This becomes important when open space is limited, and we want to generate higher solar power from that same limited space. Such a situation occurs when your roof is not enough, or the orientation roof is in the wrong direction. Sometimes, people want to go 100% solar. In such circumstances, monocrystalline panels become a more viable option.

Monocrystalline And Polycrystalline Solar Panels: Know The Difference
by Gennex Technologies | Jun 4, 2020 | General |
One of the question clients like to ask when shopping for solar panel is between Monocrystalline and Polycrystalline solar panels which should i get? well today we will look into this.
According to Energy Sage, both monocrystalline and polycrystalline solar panels are built to serve the same function in the overall solar PV system: they capture energy from the sun and turn it into electricity. They are also both made from silicon, which is used for solar panels because it is an abundant, very durable element. Many solar panel manufacturers produce both monocrystalline and polycrystalline panels.
Both monocrystalline and polycrystalline solar panels can be good choices for your home, but there are key differences between the two types of technology that you should understand before making your final solar purchase decision. The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from many silicon fragments melted together.
Lowest Performance: Thin Film
Thin film solar panels have incredibly low efficiency ratings. As recently as a few years ago, thin film efficiencies were in the single digits. Researchers have recently achieved 23.4% efficiency with thin film cell prototypes but thin film panels that are commercially available generally have efficiency in the 1013% range.
In order to meet your energy needs, you would need to install more thin film panels over a large area to produce the same amount of electricity as crystalline silicon solar panels. This is why thin film solar panels dont really make sense for residential installations where space is limited.
Fun fact! Thin film panels have the best temperature coefficient
Despite having lower performance specs in most other categories, thin film panels tend to have the best temperature coefficient, which means as the temperature of a solar panel increases, the panel produces less electricity. The temperature coefficient tells you how much the power output will decrease by for every 1*C over 25*C the panel gets.
The standard temperature coefficient for mono and polycrystalline panels typically falls somewhere between -0.3% and -0.5% per *C. Thin film panels on the other hand, are around -0.2% per *C – meaning thin film panels are much better at handling the heat than other panel types.

Monocrystalline Vs Polycrystalline Solar Panels: An Overview
Solar panels are rectangular-shaped devices consisting of solar cells, also known as photovoltaic cells.
They are used for capturing and converting solar energy into electricity.
You can use the electricity generated from these solar panels to power electrical loads.
Solar panels consist of individual solar cells. They include layers of silicon, phosphorous, and boron.
The phosphorous provides the negative charge, while the boron provides the positive charge.
Solar panels normally absorb some particles of energy, also known as photons. By so doing, they generate an electric current.
This whole process of generating current is called the
The photovoltaic effect is the process by which the photovoltaic cell converts the energy it receives from sunlight into electricity.
Solar panels dont easily wear out and can last for a long period of time.
They are very useful for homes because they dont emit greenhouse gases like carbon-based energy sources.
Solar panels are also eco-friendly. They dont lead to any form of pollution since they generate their energy from a clean source sunlight.
The only major drawback of solar panels is that they dont come cheap.
Also, they are usually installed outside the house and need sufficient sunlight to get charged.
However, in spite of their drawbacks, they are more reliable and sustainable than most energy sources.
They can add value to your home and help to reduce your monthly electric bill.

Efficiency And Temperature Coefficient
As mentioned above, monocrystalline solar panels have a higher efficiency. However, this does not mean that polycrystalline solar panels are inferior products you can find high-quality solar panels of both types. Here are a few more facts about efficiency:
- When a solar panel has a higher efficiency, it converts a larger percentage of sunlight into electricity.
- As of 2021, polycrystalline panels have typical efficiencies below 20%, while the best monocrystalline panels are approaching 23%.
- You will need more polycrystalline panels to reach a certain kilowatt-hour output per month, since their efficiency is lower.
- All solar panels suffer a temporary efficiency drop when their temperature increases, but monocrystalline solar cells are less affected by heat.
Why You Shouldnt Rule Out Polycrystalline Panels
While monocrystalline panels have a higher efficiency, polycrystalline panels can still make sense depending on your situation. While, as weve discussed, they are less efficient than monocrystalline panels, if you have a ton of space to work with, this may not be a big issue. Because their price point is lower, it could be cost-effective for you to install more polycrystalline panels on your property to meet your energy demands.
Polycrystalline panels may also be worth it for you depending on where you live. Generally speaking, polycrystalline solar panels have a higher temperature coefficient which means they lose more productivity when they heat up but, if you live in an area with a cooler climate, this wont impact you as much! Additionally, technology is rapidly improving and there are polycrystalline solar panels being produced that now have a lower temperature coefficient as well.

Which Type Of Solar Panel Should You Get
While there are benefits in choosing either monocrystalline solar panels or polycrystalline solar panels, the edge goes to monocrystalline solar panels. These panels rank better for efficiency, temperature coefficient and lifespan. However, these advantages come with a cost, as the price for a monocrystalline solar panel system can be thousands of dollars more than a polycrystalline system. Yet, there are only winners in this scenario. People who don’t want to spend the added cost for monocrystalline solar panels can still enjoy the benefits of green energy and the potential for lower electricity bills by using a polycrystalline solar panel system.
What Is The Difference In Performance
The efficiency of a solar panel is the ratio between the amount of energy it collects compared to the amount of energy it produces, the rest being lost in heat. An efficiency of 20% means that 20% of the solar radiation is transformed into electricity and that the missing 80% is transformed into heat. The higher the efficiency, the greater the amount of electricity produced.
That said, monocrystalline solar panels perform better than polycrystalline solar panels due to the fact that monocrystalline solar cells are composed of a single crystal rather than a conglomerate of crystals, which increases their spectral response and thereby their energy production.
Concretely, the efficiency of monocrystalline solar panels varies between 16 and 24% while that of polycrystalline solar panels varies between 14 and 20%. That means that on an equal surface, monocrystalline solar panels are more efficient. These panels are often suggested for those whose space is a limiting factor.
Another great advantage of monocrystalline solar panels is that the crystal purity of their cells means that their production starts earlier and stops later than a polycrystalline solar panel. Not only being more efficient, this type of panel will have a longer energy production period than that of a polycrystalline solar panel.

How Efficient Is A Mono Solar Panel
The solar panels efficiency rating is a measure of how good the cell is in converting energy from the sun into electricity. The more efficient the solar cell is, the less the installation space it requires.
Monocrystalline cells typically have the highest efficiency of all types of solar panels. Their efficiency rating can range from 15-20% or even higher, making them your best bet if your PV system is limited by the amount of space on your roof.
Mono cells have the highest efficiency and power capacity because theyre made from single-crystal silicon. As a result, electrons get ample space to move quickly through the cell to improve electricity flow.
Monocrystalline solar cells produce more power per square foot than polycrystalline cells, so theyre very space-efficient.
Additionally, they post better performance even in low light conditions. These panels also tend to be more effective in warm weather conditions.
Monocrystalline V/s Polycrystalline Solar Panels: Deciding Factors
If you are still confused about the decision between monocrystalline and polycrystalline solar panels, then consider these factors before making your decision.
Space constraint
If you have limited rooftop space available for solar installation, you should consider going for monocrystalline solar panels as 50 to 60% higher power capacity can be achieved in the same area as compared to polycrystalline panels. While the up-front cost of mono panels is higher, having a higher capacity plant will be beneficial in the long run by reducing your electricity bills much more.
On the other hand, if you have ample rooftop space available to go for a larger solar installation, then you can consider polycrystalline solar panels as a more economical option.
Personal Preferences
If you are looking for aesthetically pleasing solar panels for your roof, then you might consider monocrystalline solar panels. Their sleek design and black hue offer an aesthetic appeal to your solar structure. Alternatively, if you like to go with the simpler structure, then you can consider polycrystalline solar panels, which have a light blue tint.

What Polycrystalline Solar Panels Are
Polycrystalline solar panels are made of individual polycrystalline solar cells.
Just like monocrystalline solar cells, polycrystalline solar cells are made from silicon crystals. The difference is that, instead of being extruded as a single pure ingot, the silicon crystal cools and fragments on its own. These fragments are melted in an oven and formed into cubes which are cut into thin wafers. So, many different crystals form this amalgam, rather than the single crystal of the monocrystalline solar cell type. Its a less exacting production process than with monocrystalline cells, so it allows for more solar cells to be produced faster and less expensively.
The blue-colored square polycrystalline cells fit neatly side by side, eliminating any empty space between the cells. Polycrystalline solar panels operate less efficiently than monocrystalline panels because the melted fragments of silicon afford less room for the electrons to move around.
Polycrystalline panels generally have an efficiency rating of between 13% and 16%. While only a few percentage points less than monocrystalline panels, its a difference that can count for a lot when compounded across many solar panels.
