Which is better Monocrystalline or Polycrystalline Solar Panels 2023

In many parts of the world, access to reliable electricity is limited or even non-existent, leaving communities in energy poverty. Solar panels present a viable solution to address this issue and provide clean and sustainable energy to underserved areas. By harnessing the abundant sunlight, solar panels can generate electricity without the need for extensive grid infrastructure.

Solar panels are particularly well-suited for off-grid applications, where they can power individual homes, schools, healthcare facilities, and community centers. These installations often use small-scale solar systems with battery storage, allowing for electricity usage even during the night or on cloudy days. Solar-powered microgrids are also being implemented to provide electricity to entire villages, enabling economic development and improving the quality of life for residents.

Solar energy, once considered a byproduct of carbon-based energy sources, is now rapidly expanding and powering more homes than ever before. One-third of the estimated 3 million solar installations across the country were built in the last few years, with searches for the best solar companies increasing year after year.

So it is worthwhile to investigate all aspects of your solar energy system, particularly the decision between monocrystalline and polycrystalline solar panels. The type of solar panel you choose affects efficiency, cost, and durability.


What a Solar Panel Is?

Solar panels are classified into two types: thermal and photovoltaic. Thermal solar panels concentrate sunlight in order to generate heat. Photovoltaic (PV) solar panels absorb solar energy and convert it to electricity.

Photovoltaic solar panels are frequently regarded as the best solar panels for residential use by homeowners. Though less efficient than solar thermal panels, they are more suitable for residential use because they do not require large facilities.

A solar panel is similar to a picture frame. It is rectangular, with a metal frame around it and protective glass on the front. A solar panel has several layers, the most important of which is the layer containing the matrix of solar cells.

Each solar panel contains anywhere from 32 to 96 solar cells that are wired together side by side and produce anywhere from 230 to 275 watts of electricity.

Monocrystalline or polycrystalline solar cells are available. Monocrystalline solar cells make up the more expensive panel because they capture the sun's rays more effectively. However, polycrystalline panels are less expensive and can be a good option in areas with high sunlight.


What is Monocrystalline Solar Panel?

Monocrystalline solar cells are used to create monocrystalline solar panels, also known as mono panels. Each solar cell is a piece of a silicon crystal that was grown specifically to be used in solar panels.

The crystal is developed into an ingot shape in the laboratory before being divided into thin discs. To create octagons, the edges of each disc are cut.

The octagonal shapes of the solar panels enable them to fit the greatest number of solar cells into the array when the solar cells are mounted on them. Similar to cookies on a baking sheet, it. Octagonal cookies can be packed closely together with little wasted space, whereas even round cookies that are placed closely apart always have spaces between them.


Monocrystalline solar panels are recognizable by their dark color and typically range in efficiency from 15% to 20%, though some more recent experimental models have even reached close to 50%.


What are Polycrystalline Solar Panels?

Individual polycrystalline solar cells are used to create polycrystalline solar panels (also known as poly panels).

Polycrystalline solar cells are created from silicon crystals, just like monocrystalline solar cells. The distinction is that the silicon crystal cools and breaks apart on its own, as opposed to being extruded as a single pure ingot. These pieces are broken up and then melted in an oven to form cubes, which are then divided into thin wafers. This amalgam is made up of many different crystals as opposed to the monocrystalline solar cell type's single crystal. It allows for more solar cells to be produced faster and more affordably than with monocrystalline cells because the manufacturing process is less exacting.

The square polycrystalline cells were blue and neatly stacked one on top of the other with no gaps. Because there is less space for electron movement in polycrystalline solar panels than in monocrystalline ones, they perform less well than monocrystalline ones.

Typically, polycrystalline solar panels have an efficiency rating of 13% to 16%. Despite being only a few percentage points less efficient than monocrystalline panels, this difference can add up when multiplied by a large number of solar panels.


Monocrystalline Solar Panel Pros and Cons


  • Highly efficient at producing energy
  • Panels require less space
  • Black panels blend with darker shingles or foliage
  • Better heat tolerance


  • Expensive
  • Less sustainable production methods


Polycrystalline Solar Panel Pros and Cons


  • Less expensive than monocrystalline panels
  • Lifespan comparable to that of monocrystalline panels yet at a lower cost


  • Panels require more space
  • Less efficient at producing energy
  • Less sustainable production
  • The bluish color stands out more than the black of the polycrystalline panels
  • Less heat tolerance


Best Applications for Monocrystalline Solar Panels

  • Smaller applications
  • Areas with less sunlight
  • Efficiency, not cost, is more important
  • Appearance is an issue


Since they produce more electricity on a smaller scale than polycrystalline solar panels, monocrystalline solar panels are ideal for locations with a limited amount of space. Even in locations with less sunlight, monocrystalline solar panels can capture the maximum amount of energy. They are therefore perfect when cost is less of a concern than efficiency.

Although all solar panels are large, monocrystalline panels blend into the background more effectively than poly units due to their dark color.

Compared to polycrystalline panels, monocrystalline solar panels typically have better heat tolerance. As a result, they are a wise choice for hot climates like the desert.


Best Applications for Polycrystalline Solar Panel

  • Larger areas
  • Areas with maximum sunlight
  • Cost is most important
  • Aesthetics not a priority


When you need to keep an eye on the bottom line, polycrystalline solar panels are the best option.

As long as you have enough space for the panels, polycrystalline units are a better value because monocrystalline panels typically cost about $0.05 per watt more.

Due to their lower output, polycrystalline solar panels perform better in areas with abundant sunlight.

The polycrystalline panels' bluish tint and speckled appearance might not be to everyone's taste, especially if they are installed extensively in residential areas. However, they are effective in rural or urban settings where it is practical to tuck away the panels, such as on a rooftop or at the back of the property.


Aspect of Monocrystalline Solar Panels

• Monocrystalline solar panels have a higher conversion efficiency, which means they produce more kW/hour of electricity.

• Monocrystalline panels have higher heat resistance than other panels, which means that their electricity production capacity is less affected by heat and they produce electricity at a higher efficiency at high temperatures.  Because the manufacturing process for single-crystal silicon cells is complex, monocrystalline panels are more expensive than other panels.

Aspect of Polycrystalline Solar Panels

• Polycrystalline solar panels have lower efficiency than monocrystalline solar panels because they are made up of multiple silicon crystals, resulting in limited space for electrons to move.

• Polycrystalline panels are distinguished by the square shape of the cells and a bright blue hue with straight edges.

• These panels are less expensive than monocrystalline solar panels because the manufacturing process is simpler and uses less silicon.


What is the best type of solar panel?

The best solar panel option is one that is compatible with your property and personal requirements. The solar panel efficiency rating may be the most important factor for some, while cost-effectiveness may be more important for others. Here are some things to remember:

  • Crystalline solar panels are the most efficient of any type of panel.
  • Monocrystalline panels are the most efficient of all crystalline panels, ranging from 15 to 22% efficiency.
  • Polycrystalline panels have an efficiency of 15-17% and can be the most cost-effective option.
  • Thin film solar panels are the most durable and suitable for unusual roof designs.


Impact of solar panel installations in developing regions

The deployment of solar panels in developing regions has a profound impact on the communities they serve. Here are some key benefits:

  1. Enhanced Education: Solar-powered schools enable students to study in well-lit classrooms and access computers, internet connectivity, and educational resources. This improves the overall quality of education and provides new opportunities for learning.
  2. Improved Healthcare: Solar panels can power medical clinics, enabling essential services such as refrigeration for vaccines, lighting for surgeries and examinations, and the operation of medical equipment. This facilitates better healthcare delivery and improves health outcomes.
  3. Economic Empowerment: Solar panels create opportunities for income generation and entrepreneurship. By providing electricity to rural communities, solar-powered businesses can emerge, such as charging stations for mobile phones, small-scale enterprises, and productive uses of energy like agro-processing.
  4. Clean Energy and Environmental Benefits: Solar panels help reduce reliance on fossil fuels, lowering greenhouse gas emissions and mitigating the negative impacts of climate change. Additionally, they contribute to improved air quality and reduce the health risks associated with indoor air pollution from traditional energy sources like kerosene lamps or wood-burning stoves.


How long do solar panels last?

Both polycrystalline and monocrystalline solar panels have a lifespan of more than 25 years. While some claim that monocrystalline panels degrade faster, the type of silicon solar cell used in your solar panels usually has no effect on their useful life. The silicon in solar panels is used to convert sunlight into electricity by converting photons into electrons. Power output degrades over time, by about 0.8% per year. So, in year two, your panels should produce 99.2% of their original output, 98.4% in year three, and so on. Furthermore, solar panel warranties help to establish expectations about how long your solar panels and other equipment, such as inverters, may last.
