Bifacial vs. Monofacial Solar Panels: Which Solar Panel System Reigns Supreme?

As the world increasingly embraces renewable solar power to combat climate change and make a sustainable environment, the demand for solar panel system ultimately increased worldwide. However, solar panels have transformed over time, and Bifacial solar panels have already created their marketplace but primarily originated from Monofacial solar panels. Here, the question comes into play: what’s the difference between monofacial and bifacial solar panels, and which one is better to choose?

Monofacial vs bifacial solar panels are an extensive debate that can be acknowledged by understanding the functionalities and advantages of both solar panels. So, let’s have a more detailed look at bifacial and monofacial solar panels. 

Monofacial vs Bifacial Solar Panels

What Are Bifacial Solar Panels?

Monocrystalline and polycrystalline cells are the two ideal crystalline cells that are used in manufacturing solar PV panels, and most bifacial solar panels are made up of monocrystalline cells. Bifacial solar panels are highly efficient as they generate electrical energy from the reflective and illuminating surface, back and front. It captures the sunlight from both sides and has a stronger structure without metal gridlines. 

Here’s a breakdown of how bifacial solar panels work:

Bifacial solar panels are a type of photovoltaic technology that can capture sunlight from the front side and also from the rear side. It has a transparent appearance, making it more efficient than traditional monofacial solar panel systems. 

Front-Side Absorption

It works similarly to the traditional solar panels at the front-side absorption as it has a layer of photovoltaic cells made from semiconductor materials like silicon. When the sunlight hits the front side of the bifacial solar panel, photons start generating energy, leading to a photovoltaic effect that produces electricity. The front side absorbs more energy and uses various techniques, such as anti-reflective coatings and surface texturing, to generate electricity. 

Rear-Side Absorption

Bifacial panels have a unique quality to capture sunlight from the rear side and have great solar power panel efficiency. There’s a transparent back sheet or a glass layer on the rear side of the bifacial panel that allows sunlight to pass through the front-side solar cells and strike the ground or any other reflective surface underneath the panel. The back side of the bifacial is made of semiconductor material that doesn’t waste the reflected sunlight. It absorbs the reflected sunlight and uses it to generate electricity. 

Advantages of Bifacial Solar Panels

The bifacial solar panel system is gaining more popularity because of its efficiency and affordability. It truly offers numerous advantages, and some of them are as follows: 

Double-Sided Energy Capture

It captures sunlight from both sides, utilizing incident light on the front and reflected light from surfaces beneath. This dual absorption significantly increases energy generation, maximizing efficiency and output.

Higher Energy Yields

Enhanced absorption from both sides means more electricity generation per panel, resulting in higher overall energy yields for solar installations. They are more durable and have longer lifespans. 

Versatile Applications

Bifacial solar panels can be used in ground-mounted arrays, on rooftops, or integrated into building designs, making them suitable for various applications, including residential, commercial, and utility-scale projects.

Enhanced Performance in Certain Conditions

They perform exceptionally well in unsupportable environments and capture low-angle sunlight. Additionally, they adapt to changing conditions, improving energy generation throughout the day.

Factors to Consider For Bifacial Solar Panels

There are several factors that need to be considered before installing a bifacial solar panel system. Here are some of the factors that you should consider: 

What Are Monofacial Solar Panels?

Monofacial solar panels are designed with traditional photovoltaic technology that captures the sunlight and converts it into electricity. It’s the most common and traditional solar panel system, having single-sided cells located at the front surface. It has high solar power panel efficiency that is widely used in various solar energy applications, including residential, commercial, and utility-scale installations.

Here’s a breakdown of how monofacial solar panels work:

A majority of solar panels available in the market have a monofacial structure that captures sunlight from one photovoltaic side. It works in the following manner: 

Photovoltaic Cells

Photovoltaic cells are used in monofacial solar panels that are typically made up of semiconductor material such as silicon. These cells carry the energy from the sunlight and generate electricity. 


Monofacial solar panels are encapsulated to protect the photovoltaic cells from environmental factors such as harsh weather, corrosion, low energy, and more. The encapsulation materials serve to provide structural support to the home solar system. It improves the life of the solar panel and makes it more efficient. 

Advantages of Monofacial Solar Panels

The following advantages of monofacial solar panel system are listed below: 


Monofacial solar panels are cost-efficient due to their simpler design and manufacturing process. They are typically more affordable for homeowners, and it’s an accessible choice, having a huge base of users. 

Proven Reliability

Monofacial panels have many users across the country as it has a well-established track record of reliability. It’s a traditional model that offers durability and long-term performance.

Wide Applicability

Monofacial panels are considerable for residential as well as commercial purposes and can be installed on different surfaces. It’s versatile and suitable for a broad range of applications and projects. 

Consistent Performance

It offers consistent and predictable performance under standard solar conditions. They provide reliable electricity generation, which is crucial for meeting energy needs and return on investment.

Lower Maintenance

You don’t need to worry about maintenance costs if you install a monofacial solar panel system, as it has a simple design requiring minimal maintenance. It’s a great investment that reduces your electricity bills. 

Factors To Consider For Monofacial Solar Panels

When considering the installation of monofacial solar panels, there are several important factors to take into account, and the key factors are listed below:
