Monocrystalline VS Polycrystalline Solar Modules: Which One Is Better?


Renewable energy is slowly taking over the world as the primary power source, and many companies are constantly evolving their technology and production techniques to meet the demands of people’s power consumption. Solar energy is on top of people’s lists as a clean and green energy source that is relatively simpler to harness than other renewable energy sources. Solar product manufacturing companies are developing the latest solar panel technology that offers cost-effective energy.

An example of such cutting-edge technology is the advanced Monocrystalline and Polycrystalline panels. These solar panels are one of the most efficient and save you a lot of money on your power consumption expenses. These solar panels will provide you with green and clean energy for years to come. In this blog, we will uncover the various unique features of both these panels and understand how the technology behind the panels differs from each other based on multiple parameters. Let’s dive into this fun and informative blog on cutting-edge renewable energy.

Monocrystalline Panels 

Monocrystalline solar modules are made from monocrystalline cells. Mono in monocrystalline panels refers to using a single silicon crystal in production. Each cell is a slice of a single crystal of silicon. This silicon crystal is grown into a cylindrical log shape in the lab, called an ingot. It is then sliced into thin discs cut into an octagon shape. These discs are then made up into a cell. The octagonal shape of these cells helps us fit the maximum number of cells in a solar panel. Using a single crystal in the production process is expensive, which makes them more costly. 

Our company provide you with an advanced version of monocrystalline solar panels, named mono PERC panels. PERC stands for Passivated Emitter and Rear Cell, adding a passivated layer in the cell’s rear side to achieve higher energy efficiency and sunlight absorption. The mono PERC solar panels offer extreme durability, PID resistance, low light performance, and the panel has 72 mono PERC cells. 

Polycrystalline Panels

Polycrystalline solar modules are made of polycrystalline cells, and the panels are blue in appearance. Polycrystalline solar cells are made up of multiple fragmented silicon crystals. The use of fragmented silicon crystals makes these panels more affordable than monocrystalline solar modules. The square shape of the cells helps fit more cells in the panels, eliminating wasted space.

Our polycrystalline panels go through triple EL checking to ensure we offer you a defect-free module. These panels have various applications, like on-grid rooftop residential applications, off-grid residential systems, and street lighting. The panels have a high transmittance low iron tempered glass to maximise power generation. Our panels can sustain heavy wind and snow loads, are PID-resistant, and have an anti-reflective glass coating.

The Difference

Both these panels are efficient in their own ways, and their applications cover all your residential and commercial power consumption needs. Let us take a closer look at how the technology behind these panels differs, earning them their unique features and the extraordinary qualities that make them a perfect choice for your clean energy requirements.

1. Efficiency

One of the main points of difference between the monocrystalline and polycrystalline panels is the efficiency factor that sets both panels apart. The efficiency of monocrystalline solar panels is higher than polycrystalline modules. If you use mono PERC solar modules, you can achieve greater efficiency than the standard monocrystalline modules.

2. Space Required

The higher efficiency of the monocrystalline panels enables them to generate more energy in a small space. If you go one step ahead and choose mono PERC solar modules, the efficiency is even greater as they come with an anti-reflective coating, making them space-efficient. In contrast, polycrystalline solar panels require more space for efficient energy generation, so they are less space-effective than the monocrystalline solar panels.

3. Cost Incurred

Monocrystalline solar panels are more costly than polycrystalline modules. They require less space for efficient energy generation which justifies their higher cost. The polycrystalline solar modules are less expensive and need more space for energy generation, which balances both the panels on the cost scale.

4. Appearance of The Panels

The monocrystalline solar modules are black in appearance, and so are the mono PERC panels. On the other hand, the polycrystalline solar modules are blue, making them an attractive choice for home and business owners. You can choose any of the panels based on your energy requirements and aesthetic needs.

5. Temperature Coefficient 

The temperature coefficient is the percentage of power output the solar panels lose when the temperature rises above a certain level. The temperature coefficient of monocrystalline and mono PERC panels is low, making them more heat efficient. In contrast, the temperature coefficient of polycrystalline solar panels is high, making them less efficient in the heat.

6. Life Span Of Panels

The average lifespan of monocrystalline solar panels is more than 25 years, which is a very long lifespan for any kind of solar panel. The average lifespan of polycrystalline panels is also more than 25 years, but the panel’s efficiency is slightly less. You can choose any of the two modules based on your energy consumption requirements.
