What are Bifacial Solar Cells?

Bifacial solar cells represent a significant advancement in solar technology. Unlike traditional mono facial solar panels, which capture sunlight solely from the front surface, bifacial solar cells are designed to absorb light from both sides. This unique feature allows them to harness sunlight that is reflected off nearby surfaces, such as the ground or adjacent structures.

Why are Bifacial Solar Panels Better than Monofacial Panels?

Start to learn about What are the Major Components Used for Making Solar Panels and which cover the bifacial panels. Bifacial solar panels offer several advantages over their mono facial counterparts:

Enhanced Energy Production: 

Bifacial solar panels capture sunlight from both sides, significantly increasing their energy output. This boost in efficiency can lead to greater electricity generation.

Improved Performance in Diffuse Light Conditions:

Bifacial panels perform better in low-light and overcast conditions because they can utilize diffuse sunlight and reflected light.

Lower Levelized Cost of Electricity (LCOE): 

Despite having a potentially higher upfront cost, bifacial panels’ superior energy generation can result in a lower LCOE over their lifetime.

Increased Environmental Sustainability: 

Because bifacial solar panels produce more electricity, they lower the carbon footprint associated with production and transportation, making them more environmentally friendly.

Versatile Installation Options: 

Bifacial panels can be installed on various surfaces, including tracking systems, rooftops, and even canopies, making them adaptable to different applications.

Who Makes 23.2% Efficiency For Bifacial N-Pert Solar Panels?

Several reputable manufacturers produce bifacial solar panels, including those based on the N-PERT (passivated emitter and rear totally diffused) technology. Companies like SunPower and REC Group are known to manufacture high-quality bifacial N-PERT solar panels that are renowned for their efficiency and durability.

Are Bifacial Panels Monofacial?

Bifacial panels are not monofacial panels. The primary distinction lies in their ability to capture sunlight from both the front and rear sides, while mono facial panels only absorb sunlight from their front surface. Bifacial panels are a more advanced technology designed to optimize energy generation.

How to Calculate Bifacial Solar Power Output?

Calculating the power output of bifacial solar panels involves considering several factors, including the panel’s efficiency, orientation, location, and the albedo (reflectivity) of the surrounding surfaces. A comprehensive analysis often requires the use of specialized software or consulting with a solar energy expert. You can use online solar calculators that take these aspects into consideration to get a preliminary estimate.

What Is the Distinction Between a Bifacial Cell Structure and a Conventional Cell Structure?

The key difference between a bifacial cell and a conventional cell structure lies in their design and light-capturing capabilities:

Bifacial Cell Structure: 

Bifacial cells have an additional layer on their rear side to capture and utilize reflected sunlight. This rear side can be either textured or covered with a reflective material to enhance light absorption.

Conventional Cell Structure: 

Conventional solar cells are monofacial and have a single layer for capturing sunlight, typically optimized for direct sunlight exposure.

Bifacial cells’ ability to capture sunlight from both sides makes them inherently more efficient and adaptable to various environmental conditions.

Bifacial Solar Panel Structure

Understanding the structure of bifacial solar panels is crucial to appreciate their functionality and advantages. Learn details about how solar panels are made in a lifetime. Bifacial panels have a unique design that includes the following key elements:

Front Surface:

Like monofacial panels, bifacial panels have a front surface that directly faces the sun and captures sunlight.

Rear Surface: 

The rear surface of a bifacial panel is designed to capture and utilize reflected sunlight. 

To increase light absorption, this surface can be textured or coated with a reflective substance.


A robust frame provides structural support and protects the solar cells from environmental stressors in bifacial panels. 

Glass or Transparent Backsheet:

To allow light to pass through to the rear side, bifacial panels often feature a transparent back sheet or glass on both the front and rear sides.

Cell Interconnection: 

The cells on the front and rear sides are interconnected to ensure proper electrical connectivity and energy transfer.

Bifacial Solar Panel Installation:

The installation of bifacial solar panels follows several key considerations:

  1. Orientation: Proper orientation is crucial for maximizing energy generation. Bifacial panels can be installed in a way that allows them to capture sunlight from both sides effectively.
  2. Mounting Systems: Bifacial panels can be mounted on tracking systems that follow the sun’s path throughout the day, optimizing their exposure to sunlight.

Fixed mounts can also be employed in some situations. Sustvest is having a combination of solar panel blogs.

  1. Tilt Angle:

Adjust the tilt angle of the panels to align with the sun’s path in your exact area. This angle optimization ensures that both the front and rear sides receive adequate sunlight. Surface Albedo: The albedo, or reflectivity, of the ground or nearby surfaces, plays a significant role in bifacial panel performance. Panels installed over highly reflective surfaces can benefit from increased energy production.

Bifacial Solar Panels in India:

With its sunshine, India could be a promising market for bifacial solar panels. Best Solar Panels in India 2023 is the latest updated information to guide us to know the new trends in solar panels. Bifacial solar panels in India capture sunlight from both sides, increasing energy yield. They’re effective in India’s diverse climates, boosting solar power generation and maximizing efficiency.

Bifacial Solar Panel Advantages:

Let’s take a closer look at the advantages of bifacial solar panels:

1. Enhanced Efficiency: 

Bifacial solar panels capture sunlight from both sides, significantly increasing their energy production. This boost in efficiency results in higher electricity generation and the fastest return on investment.

2. Better Performance in Diffuse Light: 

Unlike monofacial panels that primarily rely on direct sunlight, bifacial panels can utilize diffuse light and reflected sunlight, making them ideal for regions with frequent cloud cover or shading.

3. Reduced Land Footprint: 

Bifacial panels generate more power per square foot, reducing the amount of land or rooftop space required for solar installations. This is especially valuable in areas with limited available space.

4. Improved Durability: 

Bifacial panels are often built with robust materials and construction, increasing their resistance to environmental factors such as wind, snow, and hail.

5. Environmental Benefits: 

By producing more electricity per panel, bifacial technology contributes to a lower overall carbon footprint for solar installations, making them a greener choice.
