    Monocrystalline solar panels vs. polycrystalline solar panels: Find out which ones are right for you

    What’s the difference between these types of solar panels?

    In the last decade, more people across the country have chosen to take advantage of green energy and use solar power for their homes. In 2008, the U.S. produced 0.34 GW of electricity from solar panels. Today, that number has skyrocketed to 97.2 GW. This total accounts for about 3% of the country’s electricity.- enough to power about 18 million homes. During this time, the average cost to purchase and install a solar panel system has dropped more than 70%.

    There are many factors to consider before making the decision to purchase and install solar panels. Among these are the cost, location of your house, amount of sun you receive and more. Once you’ve committed to solar energy, you’ll want to review everything you need to know about solar panels. But, before you can purchase a system, the first decision you need to make is which type of solar panels to install — monocrystalline or polycrystalline.

    Both monocrystalline and polycrystalline solar panels are made from silicon. However, the manufacturing process differs, which results in a difference in the efficiency of the solar panels. Let’s explore the differences and similarities in the two types of panel.

    Monocrystalline solar panels

    Monocrystalline solar panels are made from a single silicon ingot. To create ingots, a rod of pure crystal silicon, called a seed crystal, is placed in molten silicon. It is then slowly pulled and rotated upward, turning into a single silicon ingot. The ingot is cut into thin wafers, whose surface is roughened so it can refract more sunshine. Then, a layer of phosphorous is added to each wafer. It takes between 32 and 96 pure silicon wafers to create each solar panel. The more silicon cells in each panel, the higher the energy output.

    Polycrystalline solar panels

    Polycrystalline solar panels are sometimes called multi-crystalline or many-crystal solar panels. They are also made from silicon. However, instead of being created from a single wafer, they are made from multiple silicon fragments. The silicon is melted and then cools as fragments, which are molded together before being cut for the panel. The finishing process is the same as for the monocrystalline panels.

    Monocrystalline solar panels vs. polycrystalline solar panels


    The cells for monocrystalline solar panels have square wafers with rounded corners. The result is a small gap between the cells. The solar panel looks dark due to the purity of the silicon. The cells for polycrystalline solar panels are square, without any rounded edges. They take on a blue color due to the way the sun interacts with the many crystallines.

    Winner: No clear winner


    To determine the efficiency of solar panels, the amount of captured sunshine that is converted into electricity is measured. The higher the number, the more efficient the system. Monocrystalline solar panels have an efficiency range from 15% to 20%, while the efficiency range for polycrystalline solar panels is from 13-16%.

    Winner: Monocrystalline solar panels

    Temperature coefficient

    The metric that measures how well solar panels function when the temperature is hotter is the temperature coefficient. This rate is.0.3% to.0.45% on the Celsius scale for monocrystalline solar panels. That means that for each 1oC/32oF, monocrystalline solar panels will be between 0.3-0.45% less efficient. For polycrystalline solar panels, the rate is.0.5%. The end result is that monocrystalline solar panels produce 20% more electricity, on average, than polycrystalline solar panels.

    Winner: Monocrystalline solar panels


    The amount of electricity produced by solar panels is reduced, or degrades, each year. This affects the panels’ lifespans. The annual rate of degradation for monocrystalline solar panels is 0.3 to 0.5%. Solar panel manufacturers put the rate at 0.8% and often provide 25- to 30-year warranties. However, many systems can last 40 years. The degradation for polycrystalline solar panels is slightly worse, from 0.3 to 1%, resulting in a lifespan of about 35 years.

    Winner: Monocrystalline solar panels

    Ability to recycle

    For both monocrystalline solar panels and polycrystalline solar panels, 90-95% of the component parts of the solar panels can be recycled.

    Winner: No winner


    The cost of purchasing and installing solar panels depends on the number of panels you need. Your average energy use, the output of the solar panels and the amount of sunshine at your home factor into this determination.

    The average cost per watt for monocrystalline solar panels is 1 to 1.50. A standard 250-watt panel can run from 250 to 375. This makes the average cost to purchase an entire monocrystalline system range from 6,000 to 9,000. Polycrystalline solar panels range from 0.90 to 1 per watt, or 225 to 250 per 250-watt panel. This results in an average system cost for the polycrystalline panels of 5,400 to 6,000. Monocrystalline solar panels cost more due to the method of producing single crystalline ingots.

    Winner: Polycrystalline solar panels

    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.

    Monocrystalline vs Polycrystalline Solar Panels

    There are two basic types of solar panels: Polycrystalline solar panels and monocrystalline solar panels. Although polycrystalline panels are more popular, they may not always be the best option. Read on to learn about both pros and cons of both types of solar panels.

    First things first, many US households have decided to invest in a solar energy array. As there are many different homes and uses for solar panels, over time, many different kinds of panels emerged as well. Monocrystalline and polycrystalline panels are the most popular, while the market is seeing a rise in flexible solar panels as well.

    What is a Solar Panel?

    A solar panel is a device that generates electricity. Each solar panel is made up of many solar cells, which interact with direct sunlight to excite electrons found within. This creates the current that is then taken to the inverter. The inverter turns this DC (Direct Current) electricity into AC (Alternating Current) electricity that the appliances and devices around your home can use.

    As each solar cell can only produce a small quantity of electricity, many of them are combined into a single solar panel. Solar panels can produce much more current – around 350 Watts for an average roof-mounted solar panel. Many of them can be combined to produce more power – as much as you need.

    An average home solar system usually produces 4-6 kW of electricity when exposed to direct sunlight. Large-scale solar farms can produce upwards of 100 MW, or 100,000 kW of electricity, and can supply power to thousands of households at the same time. Combined with a large-scale solar storage solution, such as batteries or pumped hydro, they can also supply power during the night. Combined with a net-metering in place, they can serve you overnight as well.

    Types of Solar Panels

    Over time, as solar power technology evolved, we got different kinds of solar cells – always made of silicon wafers. Today, there are two basic kinds of solar panels: monocrystalline solar panels and polycrystalline solar panels. There is also one more kind, thin-film solar panels, although their low efficiency makes their use limited.

    Monocrystalline Solar Panels

    The most efficient panels are monocrystalline solar panels. A typical monocrystalline panel has several solar cells, all arranged so as to cover as much space as possible. They are called monocrystalline because each solar cell is made of a single silicon crystal. They are known for their high efficiency, of around 18%, and are currently the most efficient type of solar panels.

    In the world of solar panels, monocrystalline solar panels are considered a premium solar product – they are highly efficient, stylish, and last a longer time than most polycrystalline solar panels. Monocrystalline solar panels tend to last over 25 years, while polycrystalline solar panels last around 20-30 years.

    Polycrystalline Solar Panels

    Polycrystalline panels, on the other hand, are a bit less efficient – usually 14-16%. Although this is a bit lower than with mono panels, they are cheaper and may pay off faster. Investing in poly panels will reduce your initial costs, but some people find the bluish color of the panels unattractive, especially if placed on a red rooftop. Nevertheless, they are very good and reliable. Research has also shown that poly panels may perform a bit better during overcast days or when they are covered in a thin layer of snow.

    Thin Film Solar Panels

    Thin film solar panels have different types of cells when compared to traditional solar cells. Here, solar technology allows the cells to be flexible and to be able to be wrapped around different objects. This is done by printing or applying a thin layer of photovoltaic material on top of a glass or plastic material.

    In the latter case, the plastic base allows the panel to be bendable. They are a perfect solution that is applied to roof tiles or other objects of irregular shapes, such as your RV rooftop. Some people even make them into rollup shades that can be opened as soon as you park your RV.

    Thin film solar panels are less efficient than mono panels or even poly panels. Nevertheless, their lower efficiency is compensated by a lower price. If you would like to provide energy for your home, you could do that by means of thin-film solar panels, although you would need a larger rooftop surface to do so. If space is of the essence, you should probably opt for poly solar panels or even mono panels. Covering every square foot of your home in solar panels may not be the best option, aesthetically speaking.

    Difference Between Monocrystalline Polycrystalline Solar Panels

    Mono panels vs polycrystalline solar panels – what is the difference? As we stated before, the difference is in the type of solar technology that is used in manufacturing these two types of solar cells. The electricity generated is always the same, although the voltage and amperage, as well as wattage, can be different. As most solar professionals will tell you, using a lower number of more efficient solar panels is the best option for many, but the opposite holds true for many as well.

    When comparing monocrystalline and polycrystalline solar panels, you should consider:

    • The manufacturing process,
    • The price,
    • The efficiency,
    • The lifespan,
    • The temperature coefficient, and
    • The aesthetics.

    Some experts would also add performance under stress to the list, although this is not always an important factor. We will consider them all.

    Cost High Middle Low
    Efficiency High. 15-20% 13-16% 7-18%
    Lifespan 25 years ~ 25 years 10-20 years
    Temperature Coefficient High Middle Low
    Appearance Black. stylish Blue. good for seaside Dark Blue to Black

    Manufacturing Process

    The main difference between mono vs poly solar panels is in the manufacturing process. All other differences there is the result of the fundamental difference in how they are made. While solar manufacturers use one silicon crystal to form single-crystal silicon cells (monocrystalline panels), the shards that are left over are fused together to make polycrystalline panels.

    When making a monocrystalline solar panel, manufacturers melt silicone and place it in a mold. Once the crystals are formed, they are cut and shaped. This is how a single-crystal solar cell is formed. Because they are uniform in structure, they allow for an easy passage of electrons and can allow a higher efficiency, and, ultimately, a higher price.

    All the leftover crystal pieces and shards are fused together. This is how polycrystalline solar cells are made. Connecting many of them in a single structure gives you a polycrystalline solar panel. Polycrystalline cells do not have a uniform internal structure. For this reason, multiple silicon crystals in a single solar cell allow fewer electrons to move around and allow for lower efficiency. This is the reason why polycrystalline panels are cheaper than monocrystalline panels.

    Besides this, the manufacturing process can also allow for some other changes to the panels. Half-cut solar cells, for example, have a higher efficiency than their uncut counterparts because they tolerate partial shadowing better. Likewise, installing microinverters is also done during the manufacturing process. Hotter climates, with more sunshine, will demand monocrystalline, so take this into consideration.


    As we’ve mentioned before, the technology used in the manufacturing process dictates the efficiency and the price of solar panels. As they do not come cheap, the US government and state governments offer significant rebates and other incentives to ensure that the technology is widely adopted. If the price is still too high, there are other ways to get solar panels. Financing, solar loans, and signing a power purchase agreement (PPA) are some common ways to get almost-free solar panels.


    Depending on the efficiency of the solar cells, the overall efficiency of the solar panel and the solar array can be higher or lower. In general, monocrystalline panels are more efficient than polycrystalline panels, while at the same time, they can be more efficient even with partial shading. On the other hand, the monocrystalline panels are less prone to suffer efficiency losses due to temperature rises.

    Monocrystalline panels in general feature efficiencies of 15-20%. Polycrystalline panels, on the other hand, are 13-16% efficient, and they are likely to be a better solution for more households. However, if you are limited in roof space, live in areas where high temperatures are not common, or can even sell leftover electricity on the residential market, you are better off with monocrystalline panels.


    The lifespan of monocrystalline solar cells is different from that of polycrystalline solar cells. For this reason, mono solar cells will easily outlive poly solar cells. The lifespan of mono panels is over 25 years and around 25 years for poly panels. When speaking of the life span of solar panels, it is useful to notice that the usable lifespan of these panels is considered a period in which they keep around 80% of their energy generation capacity and can therefore offset your high energy bill.

    Temperature Coefficient

    The energy output even of the best solar panels depends on outside factors, such as temperature. The efficiency of solar panels depends on this factor. Very low and very high temperatures affect energy production. High summer temperatures, for example, can significantly reduce how much energy is produced at any given moment in time. Monocrystalline solar panels are more resistant to high temperatures, and their energy efficiency is slower to degrade with an increase in temperature. This means they have a higher temperature coefficient.


    Yet another factor to consider before making your final purchase is the aesthetics of your solar panels. As the looks of your home play a considerable role in how well you feel in your home, you should know that many people find polycrystalline solar cells and panels to be less attractive than their mono-counterparts. This is because black combines better with any color and shape than a dark blue hue can. In any case, every solar panel has a lot of benefits to the environment that you should consider.

    Factors to Consider when Choosing a Solar Panel

    Now that you know how to differentiate monocrystalline vs polycrystalline solar panels, it is time to see which type works better for you and your energy needs. Here, there are many factors to consider before making your purchase. In general, you want to pay attention to:

    • Your individual preferences,
    • Your space limitations, as RV solar panels, will be different from the panels you install in your home,
    • The amount of dust, snow, and shade you can expect in your region,
    • The climate of your region, and
    • Your solar financing options.

    Individual Preferences

    When it comes to individual preferences, many people FOCUS on color. And while polycrystalline panels and their bluish hue may look better at the seaside, the mono panels, and their distinctive black color, will look better in almost all other settings. Considering that mono panels also last longer and can produce much more electricity over their lifespan, they are also a better choice for all who would like to invest for the long term.

    Space Limitations

    Space limitations can also dictate what kind of panels you should put on your roof. If the space is limited, you should go for monocrystalline panels, as every square foot of your rooftop that is under panels will be producing up to 35% more electricity than polycrystalline solar panels. Monocrystalline solar panels are also a much better option for multi-story homes and RV applications.

    If, on the other hand, you live in a large home with plenty of rooftop space compared to the square footage of your home (such as single-story houses), you should consider purchasing more polycrystalline panels. This way, you will be able to save money by sacrificing some more rooftop space. Thin-film solar panels should not be forgotten either, especially in RVs, as their blanket-like flexibility is perfect for all the imperfections in the RV roof shape.

    Amount of Dust, Snow, and Shade

    The amount of dust, snow, and shade that your panels receive will also influence the type of solar panels that you should place on your rooftop. Monocrystalline solar panels are better suited for dusty climates and climates with a lot of snow. Likewise, they can better tolerate partial shade, especially if you purchase half-cut models.

    Snowy regions also prefer mono solar panels. During the winter, they heat up faster and can produce more energy during the colder part of the year. Furthermore, as they are darker and heat up faster, they will melt any snow that may accumulate on top of them and will be ready for energy production in no time.


    The climate you live in is also a factor to consider before purchasing your solar panels. If you live in very hot or very cold regions, you should go for mono solar, as every polycrystalline panel is more sensitive to temperature fluctuations and will result in lower overall energy production. Living in a humid climate, on the other hand, can both lower and increase energy production. While clouds reduce the amount of light that hits your panels, the rain will clean them and make them more energy efficient.

    Solar Financing

    The final thing to consider is solar financing. Although panels have become much cheaper recently, installing even a polycrystalline silicon PV array, or fewer panels of the monocrystalline type can still be a significant expenditure. The US Federal Government offers significant tax credits, up to 26% of the initial investment cost.

    This tax credit can then be combined with other incentives and rebates, such as those offered by your state or even your utility company. Being aware of these incentives can save a lot of money for you and can help you increase the size of your solar array to the size you actually need. You can ask in your local municipality office or even a solar professional to learn more about how you can benefit from solar financing.

    In addition to these programs, you can also go for a solar loan with your bank. If you have a suitable flat surface and sufficient income, any bank will help you by offering a solar loan. Many banks, in cooperation with the local authorities, will even offer a zero-interest solar loan to all that are eligible.

    Solar PPA is another form of solar financing that you should consider. Under this format, you sign a Power Purchase Agreement with the installer or even a utility company. Under this agreement, you purchase all electricity that the panels produce. What is great here is that you get a heavily discounted rate. On the other hand, your electricity bills will be the highest during the summer, while your winter bills will be much lower. This is a great way to balance your energy expenditure.

    Other Solar Panel Technology

    Besides monocrystalline and polycrystalline silicon PV cell technology, the market and investments have brought about many other types of solar panels to the market. With this in mind, we will consider some of the most popular alternative solar panel technology:

    • Flexible solar panels,
    • Passivated emitter and rear cell panels (PERC),
    • Half-Cut panels,
    • Bifocal solar panels,
    • Transparent solar panels, and
    • PV shingles.

    Flexible Solar Panels

    Flexible solar panels or thin-film panels are very thin solar panels. They are made by printing silicon crystals onto a plastic surface, which acts as the structural support. As they are thin they are very flexible. This enables them to be applied to any surface that you have available, even if the surface is off-shape or otherwise irregular.

    Passivated Emitter and Rear Cell [PERC]

    Passivated Emitter and Rear Cell is a solar panel technology that introduces an additional layer of material into the panel itself. The added layer is highly reflective so that all the light that goes through the panel is reflected back, getting another chance to be absorbed. The main advantage of this type of panel is that the layer adds a lot of efficiency to it with little added cost.

    Half-Cut Cells

    Half-cut cells are monocrystalline types of PV cells that use an entire silicon crystal that has been cut in half. The main advantage of this type of PV cell is its higher resistance to partial shading, where only a portion of the solar cell is nullified and produces no electricity. Theoretically speaking, this type of technology should cut power losses due to shading by as much as 50%.

    Bifacial Solar Panels

    Bifacial solar panels are somewhat similar to PERC solar panels. In these, the passivation and reflection layer is substituted by another solar panel. The panels are usually of different kinds, so the primary panel may be monocrystalline, while the second panel may be polycrystalline. This is usually done to keep the expenses at a reasonable level. The biggest disadvantage of this type of panel is its added weight, which some roofs may not be able to support.

    Transparent Solar Panels

    Transparent solar panels, on the other hand, are a type of panel with a possible new application. Panels like this can be integrated into buildings, making the Windows absorb sunlight and produce power. There is also another type of transparent solar panel, the so-called agri-voltaic panel, which consists of two layers of glass or sturdy plastic. In between them, there are standard solar cells, placed at a bigger distance from one another. This type of panel is being tested in Europe as a protection against the sun in agricultural applications. Current results show that the crops growing under them can produce as much as 30% more biomass.

    PV Shingles

    PV shingles, on the other hand, take a different approach to producing electricity on your own roof. Solar shingles completely replace your existing roof tiles and existing solar panels. They come mostly in black color, so they are very stylish. However, as the total surface solar cells take up is smaller than with a conventional panel, you will have to consider installing them on a larger surface.


    Which Solar Panels are the Most Reliable?

    Monocrystalline solar panels are the most reliable on the market. As they are made of a single piece of silicon crystal, they are sturdier and more efficient than their polycrystalline counterparts. They also feature higher efficiency levels, so you will likely need fewer of them to satisfy your energy needs.

    How to tell the Difference Between Monocrystalline and Polycrystalline?

    Monocrystalline and polycrystalline solar panels are easy to tell apart: their color is different. Monocrystalline solar cells are black in color, while polycrystal lines are of a dark-blue shade. Besides this, they should be clearly labeled on the packaging, and monocrystalline panels will always have higher efficiency levels than monocrystalline.

    How Long Do Polycrystalline Solar Panels Last?

    Polycrystalline solar panels last up to 25 years. In reality, they can last even longer, but their efficiency levels will drop below their optimal 80%. After this happens, you can keep the same solar panel system on your roof, or you can sell them. There is also an emerging market for solar panel recycling, so, by the time their useful life is over, you will be sure they do not end up in a landfill.

    Can you Mix Poly and Mono Solar Panels?

    Yes, you can mix poly and mono solar panels. In this case, you should pay attention that there is no significant difference in their power output. If this is the case, the overall solar system may lose efficiency, although not to a large extent. You will still be able to produce power, but not as much as with a single type of solar panel. Furthermore, opting for a single kind of panel will make their installation, all the necessary calculations, and their removal and replacement much easier.


    Solar panels are the future of energy generation. When it comes to choosing the right type of solar panels, this is a headache for today. We’ve researched different types of monocrystalline vs. polycrystalline solar panels so that you do not have to. Follow our guide and see which type of panels is best suited for your climate, energy needs, available space, and any other preferences you may have.

    What is Monocrystalline Solar Panel: A Consolidated Guide

    Solar panels have been in demand due to their clean energy source and efficiency. They are also a good way to save on your utility bills in the long run. By the way, do you have a solar panel? Which one do you have, poly, mono, or thin film? Yes, there are different types of solar panels based on their efficiency, and today you will learn about what is Monocrystalline solar panel along with its its advantages, specifications, wattage, and efficiency. If you are planning on getting one, it is better to know how long do they last?

    What are Solar Panels?

    Photovoltaic cells that convert sunlight into electrical energy are known as solar panels. Solar panels are connected to inverters and solar charge controllers along with a battery bank. You already know that the extra power generated by solar panels is stored in the battery bank that powers the appliances at night. The inverter converts and supplies the current to power the appliances. The charge controller maintains the voltage supplied to the inverter and prevents it from getting over or being discharged.

    Solar panels are basically of 4 types, namely monocrystalline, polycrystalline, amorphous, and thin-film panels. Among these here you will get to know about Monocrystalline solar panels.

    What is Monocrystalline Solar Panel: A Consolidated Guide

    The type of solar panel made from monocrystalline solar cells is known as a monocrystalline solar panel. The cylindrical silicon ingot generated from high-quality single-crystal silicon is the reason behind its name. space is available for electrons to move freely, thus providing a better flow of electricity. This is possible because of the single crystal. The wafer-like appearance of the cells is due to the cylindrical slicing of the ingot. Ingots are (materials that are cast into various shapes to enable further processing of solar products).

    monocrystalline, solar, cell, inches

    Further, to increase the utility of cells to the max, these circular wafers are wire-cut into octagonal-shaped wafers. Due to their octagonal shape, these cells have a uniform color.

    Construction of Monocrystalline Solar Panels

    The single silicon crystal is formed through the Czochralski method. The seed crystal is placed at a high temperature into a vat of pure silicon (molten). As the molten silicon forms around the seed, it is picked up thus creating only 1 crystal. A large ingot or crystal is obtained which is then sliced into thin wafers to make solar cells. Based on their size, a single Monocrystalline panel may contain 60-72 solar cells, among which the most commonly used residential panel is a 60-cell Monocrystalline solar panel.

    Working Principle

    The solar energy absorbed by the cells creates an electric field. Voltage and current are the main components of this electric field. These components then generate power as per the following equation:

    Power (P) = voltage (V) current (I)

    This current is used for powering devices and appliances working on direct current (DC). You can use devices running on Alternative Current (AC) too by attaching an inverter to the solar panels. An inverter will convert the direct current into an alternating current for powering such devices.


    Monocrystalline solar panels have the following features or characteristics which you must know after you have learned what is Monocrystalline solar panel.

    • A larger surface area is provided to these solar panels due to their pyramid pattern.
    • The top surface of monocrystalline solar panels is diffused with phosphorus. This creates an electrically negative orientation on the top of the panel.
    • The bottom surface of the panel has a positive electrical orientation and together the top and bottom work in creating the electrical field.
    • These panels have a coating of silicon nitride that is best to reduce reflection and increase absorption.
    • Metal conductors are printed on the Monocrystalline solar cells and due to these, the generated electricity is collected.

    Application of Monocrystalline Solar Panels

    Being highly efficient, these solar panels have different applications, as below.

    • Used in solar power systems for rooftops in urban and rural areas.
    • The small Monocrystalline panels can generate 5 to 25 watts of electricity. It is sufficient to charge your phone, laptop, and cameras.
    • They are recommended for large-scale solar power systems like on vests of tracts of uncultivable land.
    • Panels can generate 40 to 130 watts that are used for powering refrigerators and ovens.
    • To power rural homes these panels are formed into arrays.
    • Used for lighting system in the garden.
    • The Monocrystalline panels work best as stand-alone panels for street lighting.

    Monocrystalline Solar Panel Specifications

    The general specifications of Monocrystalline solar panels are:

    6.51Ah/0.651A (10h, 1.8V/cell, 25° Celsius)

    5.95Ah/1.190A (5h, 1.75V/cell, 25° Celsius)

    5.37Ah/1.790A (3h, 1.75V/cell, 25° Celsius)

    Monocrystalline Solar Panel Efficiency

    In terms of efficiency, monocrystalline solar panels are on the top. These panels are the most efficient with an 18% to 20% rating. After seeing monocrystalline solar panel specifications, you should also learn about monocrystalline solar panel efficiency. Once you understand what is Monocrystalline solar panel is, why not learn about its efficiency?

    The efficiency rating means from 100% of the sunlight falling on the panels only about 18 to 20% is absorbed and converted into electricity. The range of efficiency may vary among different manufacturers. The overall efficiency of solar panels declines by 1% every year. After this, let’s explore monocrystalline solar panel size.

    Monocrystalline Solar Panel Size

    Now that you know about monocrystalline solar panel efficiency, you might as well explore monocrystalline solar panel size. There are different sizes available for all types of solar panels. But the size depends on the number of cells because a solar panel is made by the parallel arrangement of a series of connected solar cells. A small 5-watt solar panel takes up space of less than 1 square foot. The standard size of a solar cell is 6 by 6 inches (156 156 millimeters).

    • A 60-cell solar panel consists of 6 rows with 6 cells in width and 10 cells in length.
    • A 72-cell solar panel consists of 6 rows with 6 cells in width and 12 cells in length.
    • 60-cell solar panel 39 inches 66 inches (3.25 feet5.5 feet)
    • 72-cell solar panel 39 inches 77 inches (3.25 feet5.42 feet)

    Size of a Monocrystalline Solar Array

    The number of panels to be used in an array is determined by the wattage of the solar panels. Here is a list of 60- cell and 72-cell solar panels at different wattages and the number of panels used in them.

    Note: The overall calculation is based on developing a 6.5 kW (6500-watt) solar power system to power an average American household energy requirement.

    • 60- cell 6500W/315W = 20.6 (21 panels)
    • 60- cell 6500W/285W = 22.8 (23 panels)
    • 72- cell 6500W/375W = 17.3 (18 panels)
    • 72- cell 6500W/340W = 19.1 (20 panels)

    Therefore, what is Monocrystalline solar panel in size is an average size range between 18 and 23 panels.
