8 things You Need to Know About Monocrystalline Solar Panel

Solar panel technology has dramatically improved over the years and a range of innovative solar panels are now being introduced to the market. There are a lot of things to consider when you&#;re looking to install a solar panel system one of which is what kind of solar panels to get. Most of the solar panels on the market today for residential solar energy systems, can fit into three categories: monocrystalline solar panels, polycrystalline solar panels, and thin-film solar panels. All these types of solar cells are used to harness the sun&#;s energy. However, each of them causes solar panels to have different characteristics. In this article, we&#;ll discuss what a monocrystalline solar panel is and how it works.

The Benefits of Solar Panel

Using solar panels is a very practical way to produce electricity for many applications. The obvious would have to be off-grid living. Living off-grid means living in a location that is not serviced by the main electric utility grid. Remote homes and cabins benefit nicely from solar power systems. No longer is it necessary to pay huge fees for the installation of electric utility poles and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide power for upwards of three decades if properly maintained.

Besides the fact that solar panels make it possible to live off-grid, perhaps the greatest benefit that you would enjoy from the use of solar power is that it is both a clean and a renewable source of energy. With the advent of global climate change, it has become more important that we do whatever we can to reduce the pressure on our atmosphere from the emission of greenhouse gases. Solar panels have no moving parts and require little maintenance. They are ruggedly built and last for decades when porperly maintained.

Last, but not least, of the benefits of solar panels and solar power is that, once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system&#;s lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! For grid-tie solar power system owners, the benefits begin from the moment the system comes online, potentially eliminating monthy electric bills or, and this is the best part, actually earning the system&#;s owner additional income from the electric company. How? If you use less power than your solar electric system produces, that excess power can be sold, sometimes at a premium, to your electric utility company!

What is a monocrystalline solar panel?

A monocrystalline solar panel is a solar panel comprising monocrystalline solar cells. The panel derives its name from a cylindrical silicon ingot grown from single-crystal silicon of high purity in the same way as a semiconductor. As the cell is constituted of a single crystal, it provides the electrons more space to move for a better electricity flow.  The cylindrical ingot is sliced into wafers forming cells. To maximize the utility of the cells, the circular wafers are wire cut to an octagonal-shaped wafer. These cells have a unique look because of the octagonal shape. They also have a uniform color.

Monocrystalline solar panel construction

As mentioned above, monocrystalline solar panels get their name from how they are made. Each of the individual solar cells contains a silicon wafer that is made of a single crystal of silicon. The single crystal is formed using the Czochralski method, in which a &#;seed&#; crystal is placed into a vat of molten pure silicon at a high temperature. The seed is then drawn up and the molten silicon forms around it, creating one crystal. The large crystal also called an ingot, is then sliced into thin wafers that are used to make the solar cells.

Usually, a monocrystalline panel will contain either 60 or 72 solar cells, depending on the size of the panel. Most residential installations use 60-cell monocrystalline silicon panels.

Monocrystalline solar panel working principle

When sunlight falls on the monocrystalline solar panel, the cells absorb the energy, and through a complicated process create an electric field. This electric field comprises voltage and current and generates power which is governed by the equation P (power) = V (voltage) x I (current). This power can be used directly to power devices that run on direct current (DC). This power can also be converted to alternating current (AC) using an inverter.

Monocrystalline solar panel Performance

Monocrystalline solar panels usually have the highest efficiency and power capacity out of all types of solar panels. Monocrystalline panel efficiencies can range from 17% to 20%.

Because monocrystalline solar cells are made out of a single crystal of silicon, electrons can flow easier through the cell, which makes the PV cell efficiency higher than other types of solar panels. The higher efficiency of monocrystalline solar panels means that they require less space to reach a given power capacity. So, monocrystalline solar panels will usually have a higher power output rating than either polycrystalline or thin-film modules.

In other words, you would need less monocrystalline solar panels in your solar power system to generate the same amount of power that, say, a greater number of polycrystalline solar panels would. This makes monocrystalline solar panels ideal for people with limited roof space.

Monocrystalline solar panel Features

Monocrystalline solar cells are among the three types of materials that exhibit photovoltaic properties. The other two are polycrystalline solar cells and amorphous or thin-film solar panels. Monocrystalline solar cells characteristics are as follows:

• These cells in the panel have a pyramid pattern which offers a larger surface area to collect more energy from the sun&#;s rays.
• The top surface is diffused with phosphorus which helps to create an orientation that is electrically negative as compared to the bottom which has a positive electrical orientation, which in turn helps to create the electric field.
• To reduce reflection and thereby increase absorption, the cells are coated with silicon nitride.
• The produced electricity is collected through metal conductors printed onto the cells.

Monocrystalline solar panel Applications

Monocrystalline solar panels have many applications as follows:

• Being more efficient, these panels can produce more electricity for the same area as occupied by panels made of other materials. These panels are quite popular among solar rooftops in urban and rural areas.
• These panels are highly recommended for solar applications on a larger scale, on vast tracts of uncultivable land.
• Smaller panels generating between 5 and 25 Watts of electricity are useful for charging phones, cameras, and laptops.
• Panels generating between 40 and 130 Watts are useful for powering higher wattage appliances such as refrigerators and microwave ovens.
• These panels are extremely useful in lighting up gardens
• These panels can form an array and are used to power rural homes.
• These panels are perfect for street lighting as stand-alone panels.

Monocrystalline solar panel Cost

Monocrystalline solar panel&#;s price is higher than other kinds of solar panels because of the way these panels are manufactured. Their high efficiency and power ratings also bump up the price. Most premium solar panels, like the SunPower X-series and the LG NeON panels, are monocrystalline.

According to the Lawrence Berkeley National Laboratory, monocrystalline solar panels sell for about $0.05 per watt higher than polycrystalline modules. As solar technology and manufacturing has improved, the price difference between polycrystalline and monocrystalline panels has shrunk.

Monocrystalline Solar Panel Advantages and Disadvantages

While they are the most efficient solar cell on the market, several advantages and disadvantages come with monocrystalline solar panels, each of which is listed below.

Here are some of the advantages of monocrystalline solar panels:

• They have the highest level of efficiency at 17-22%.
• They require less space compared to other types due to their high efficiency.
• Manufacturers state that this form of solar cell lasts the longest, with most giving them a 25-year warranty.
• These panels exhibit greater heat resistance.
• They perform better in low levels of sunlight, making them ideal for cloudy areas.

Here are some of the disadvantages of monocrystalline solar panels:

• They are the most expensive solar cells on the market, and so not in everyone&#;s price range.
• The performance levels tend to suffer from an increase in temperature. However, it is a small loss when compared to other forms of solar cell.
• There is a lot of waste material when the silicon is cut during manufacture.

Monocrystalline solar panel vs. polycrystalline solar panels

While both monocrystalline and polycrystalline work on the same principle of capturing solar energy and both will go a long way in reducing your electricity bills, there are few basic differences between the two. The main difference between monocrystalline and polycrystalline solar cells in Hindi 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.

The differences between monocrystalline and polycrystalline solar panels are mentioned in the following chart.

To choose between the best monocrystalline solar panels and polycrystalline solar panels, you should evaluate them on the following parameters.

• Price: Monocrystalline solar panels for sale will be relatively more costly compared to polycrystalline solar panels. You should draw a careful cost-benefit analysis and determine your budget to make the right choice for you.
• Efficiency: Among the key advantages of monocrystalline solar panels is their high-efficiency rate. These products are made from superior grade silicone, which has a single-crystal structure. Therefore, electricity flow has minimal resistance in these cells. On the other hand, although one of the advantages of polycrystalline solar panels is their lower price, their efficiency is also lower (between 14 and 16 percent) due to their reduced silicon purity.
• Lifespan: When you compare the initial installation costs between monocrystalline vs. polycrystalline solar panels, you should also look at the average lifespan of each. Monocrystalline solar panel manufacturers will usually offer a 25-year warranty because of the longer lifespan of the product. On this parameter of lifespan, polycrystalline solar panels are not very different, but the warranty period offered by the manufacturers may vary.
• Temperature Coefficient: In warm weather, monocrystalline solar panels can deliver higher efficiency because of their higher temperature coefficient. The output degradation in monocrystalline panels is lower as the temperature rises. If you are living in a region where the summers are longer and warmer, you should carefully consider the temperature coefficient of the solar panels you are choosing.
• Aesthetics: Attractive physical appearance of the solar panels depends on an individual&#;s sense of aesthetics. But many users find that the speckled blue hue of polycrystalline silicon is not too easy on the eyes. Therefore, they may prefer monocrystalline solar panels as they find them more uniform in appearance, and thus more aesthetically desirable.
• Space: If the available space on your roof is limited but you need more solar output, you may consider monocrystalline solar panels because of their higher efficiency.  It is worth paying the additional cost for these panels in your situation because you can maximize your power output even within your space constraints to accommodate a PV system.

Uses of Solar Panels

Solar panels are used in various industries as per the necessity and requirement. The uses of solar panels are listed below:

• Dairy: Solar panels can be used to generate power which can be used in the dairy industry for the process of sterilization, pressurization, concentration, drying, and boiler feedwater.
• Tinned Food: Here, the solar panels can provide temperature which can prove useful for processes like sterilization, pasteurization, bleaching, and cooking.
• Textile: Textile industry depends on the extensive use of solar panels for efficient use of solar energy. These are used for the process like bleaching, dyeing, drying, degreasing, pressing, etc.
• Paper: In this industry, the use of heat is required for various processes and uses solar panels to provide heat for the process like drying, boiler feed water, bleaching, etc.
• Chemical: These industries use solar panels for generating heat which is used for the production of soaps, synthetic rubber, processing heat, preheating water, etc.
• Beverages: We can see major uses of solar panels in beverage industries for the processes such as washing sterilization and pasteurization.
• Timber and by-products: Solar panels are used in the timber industry in the processes of drying, thermodiffusion beams, pre-heating water, and in the preparation of pulp.
• Plastics: Solar panels are used to generate heat which is used in the process such as preparation, distillation, separation, extension, drying, blending, etc.

 

There are three main types of solar panels used in solar projects: monocrystalline, polycrystalline, and thin-film.

Each kind of solar panel has different characteristics, thus making certain panels more suitable for different types of solar installations. 

Luckily, we&#;ve created a complete guide to help you differentiate each type of panel, and help you decide which type is right for your home.

Key takeaways

• There are three different types of solar panels: monocrystalline, polycrystalline, and thin film.

• Monocrystalline solar panels are highly efficient and have a sleek design, but come at a higher price point than other solar panels.

• Polycrystalline solar panels are cheaper than monocrystalline panels, however, they are less efficient and aren&#;t as aesthetically pleasing.

• Thin film solar panels are the cheapest, but have the lowest efficiency rating and require a lot of space to meet your energy needs.

• The brand of solar panels and the solar installer you choose is far more important than which type of solar panel you install.

Three types of solar panels

1. Monocrystalline

Monocrystalline solar panels are the most popular solar panels used in rooftop solar panel installations today. 

Monocrystalline silicon solar cells are manufactured using something called the Czochralski method, in which a &#;seed&#; crystal of silicon is placed into a molten vat of pure silicon at a high temperature. 

This process forms a single silicon crystal, called an ingot, that is sliced into thin silicon wafers which are then used in the solar modules. 

2. Polycrystalline

Polycrystalline panels, sometimes referred to as &#;multicrystalline panels&#;, are popular among homeowners looking to install solar panels on a budget.

Similar to monocrystalline panels, polycrystalline panels are made of silicon solar cells. However, the cooling process is different, which causes multiple crystals to form, as opposed to one. 

Polycrystalline panels used on residential homes usually contain 60 solar cells. 

3. Thin-film

Thin film solar cells are mostly used in large-scale industrial and utility solar installations because of their lower efficiency ratings, but you can purchase portable thin-film solar panels from BougeRV.

Thin film solar panels are made by depositing a thin layer of a photovoltaic substance onto a solid surface, like glass. Some of these photovoltaic substances include Amorphous silicon (a-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe). Each of these materials creates a different &#;type&#; of solar panel, however, they all fall under the thin film solar cell umbrella.

During the manufacturing process, the photovoltaic substance forms a thin lightweight sheet that is, in some cases, flexible. 

Solar panel type by performance

Highest performance: Monocrystalline

Efficiency ratings of monocrystalline solar panels range from 17% to 22%, earning them the title of the most efficient solar panel type. The higher efficiency rating of monocrystalline panels makes them ideal for homes with limited roof space, as you&#;ll need fewer panels to generate the electricity you need. 

Monocrystalline solar panels have their manufacturing process to thank for being so efficient. Because monocrystalline solar cells are made of a single crystal of silicon, electrons are able to easily flow throughout the cell, increasing overall efficiency. 

Not only do monocrystalline panels have the highest efficiency ratings, they typically also have the highest power capacity ratings, as well. Most monocrystalline panels on the market today will have a power output rating of at least 320 watts, but can go up to around 375 watts or higher! 

Mid-tier performance: Polycrystalline

Polycrystalline panel efficiency ratings will typically range from 15% to 17%. The lower efficiency ratings are due to how electrons move through the solar cell. Because polycrystalline cells contain multiple silicon cells, the electrons cannot move as easily and as a result, decrease the efficiency of the panel. 

The lower efficiency of polycrystalline panels also means they tend to have a lower power output than monocrystalline panels, usually ranging between 240 watts and 300 watts. 300 watt solar panels aren't seen as often in residential applications, but some polycrystalline panels have power ratings above 300 watts. 

However, new technologies and manufacturing processes have given the efficiency and power ratings of polycrystalline panels a slight boost over the years, slowly closing the performance gap between mono and polycrystalline panels. 

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 10&#;13% 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 don&#;t really make sense for residential installations where space is limited. 

Fun fact! Thin film panels have the best temperature coefficients!

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. 

Calculate your solar panel payback period

Solar panel type by cost

Highest cost: Monocrystalline panels

Monocrystalline panels are the most expensive of the three types of solar panels because of their manufacturing process and higher performance abilities. 

However, as manufacturing processes and solar panel technology in general has improved, the price difference between monocrystalline and polycrystalline panels has shrunk considerably. According to the Lawrence Berkeley National Laboratory, monocrystalline solar panels now sell for just about $0.05 per watt higher than polycrystalline modules.

Mid-cost: Polycrystalline panels

Historically, polycrystalline panels have been the cheapest option for homeowners going solar, without majorly sacrificing panel performance. Low prices allowed polycrystalline panels to make up a significant market share in residential solar installations between and . 

But as we said earlier, the price gap between monocrystalline and polycrystalline panels is narrowing. Now, more homeowners are willing to pay a slightly higher price to get significantly better efficiency and power ratings from monocrystalline panels. 

Lowest cost: Thin-film panels

Thin film solar panels have the lowest cost of the solar panel types, largely because they are easier to install and require less equipment. However, they also have much lower performance abilities and require a substantial amount of space to generate enough electricity to power a home. 

Plus, thin film panels degrade much faster than other panel types, meaning they need to be replaced more often, which leads to more long-term recurring costs. 

Solar panel type by appearance

Most attractive: Thin film panels

Thin film panels have a clean, all-black look. Their thin design allows them to lie flat against roofs, so they are able to blend in more seamlessly. In fact, with some thin film panels, it&#;s hard to even see the individual cells within the panel. They also tend to have less wiring and busbars, meaning there&#;s less white space. 

However, because they are so inefficient, you would need to cover your entire roof in thin film panels - which may or may not be your style. 

Mid-tier appearance: Monocrystalline panels

Monocrystalline panels have a solid black appearance, making them pretty subtle on your roof. But, the way monocrystalline solar cells are shaped causes there to be quite a bit of white space on the panel. Some manufacturers have worked around this with black packing or shaping the cells differently, but these aesthetic changes can impact both the price and performance of the panels. 

Overall, monocrystalline panels still look sleek, but they&#;re a bit more pronounced than thin film panels. 

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 aren&#;t 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. 

What is the best type of solar panel for your home?

Monocrystalline solar panels are the best solar panel type for residential solar installations. 

Although you will be paying a slightly higher price, you&#;ll get a system with a subtle appearance without having to sacrifice performance or durability. Plus, the high efficiency and power output ratings you get with monocrystalline panels can provide you with better savings over the lifetime of your system.

If you&#;re on a tight budget, polycrystalline panels might make more sense for you. We do not recommend thin film solar panels for residential installations - their performance and durability don&#;t make the low cost worth it, and it&#;s unlikely you&#;ll have nearly enough space to install the number of thin film panels you would need to cover your household electricity usage. 

Here&#;s a quick summary to help you choose the right one for your home!

Monocrystalline solar panels

• Characterized by smooth, black appearance and high-quality silicon

• Occupy less space and have a longer lifespan

• Formed through energy-intensive production process which generates a lot of waste

• Carry a higher price tag for installers and consumers

Polycrystalline solar panels

• Characterized by visible crystals, more scattered look, and lower-quality silicon

• Require slightly more space for producing the same amount of energy as black panels

• Less complicated production process with minimal waste production

• More affordable

Factors to consider besides solar panel type

There are two things we here at SolarReviews think are more important than solar PV cell type when choosing panels for your home: the brand of solar panels and finding the right solar installer.
