Benefits of Bifacial Solar Panels Over Monofacial Solar Panels

Unveiling the Advantages of Bifacial Solar Panels: A Complete Guide

Let’s delve into the realm of renewable energy and shed light on the exceptional capabilities of bifacial solar panels

These remarkable energy harvesters have the unique ability to capture sunlight from both the front and rear sides, thanks to their reflective back or the ingenious dual-panel glass design housing the solar cells. In this blog post, we’ll delve deeper into the intricate workings of bifacial solar panels and their unique solar energy absorption mechanism.

Bifacial Solar Panels

How Do Bifacial Solar Panels Work?

Bifacial solar panels operate similarly to their conventional counterparts. They efficiently convert a portion of direct sunlight into usable electricity through solar cells.

However, what sets them apart is their ability to harness an additional portion of sunlight that enters the panel and gets reflected within the glass until it finds its way to be absorbed by another solar cell. This intriguing phenomenon, known as the albedo effect, plays a pivotal role in the operation of bifacial solar panels, making them an exceptional choice for maximizing energy generation. 

When flush mounting on a rooftop, these panels prevent any reflected light from reaching the backside of the cells. This attribute makes bifacial modules particularly advantageous for flat commercial rooftops and ground-mounted arrays. 

The additional space allows for greater tilt and enables reflected light to bounce toward the rear of the modules, further enhancing their performance.

Benefits of Bifacial Solar Panel

Prepare to be amazed as we unravel the myriad benefits of these cutting-edge energy solutions. Below, we present a captivating glimpse into the remarkable advantages that bifacial solar panels bring to the table. 

Better Performance: Harness the power of innovation with bifacial solar panels as they unlock a new era of energy generation. By capturing sunlight from both sides, these marvels produce a significant boost in power output. 

Certain manufacturers assert that bifacial panels can generate up to a remarkable 30% more energy than their monofacial counterparts. This enhanced efficiency not only means more electricity but also allows homeowners to optimize space by installing fewer panels while fulfilling their energy requirements. 

Durability: When it comes to durability, bifacial solar panels shine with their frameless design and robust construction. Encased in tempered glass on both sides, these panels offer exceptional resistance to various weather conditions, UV rays, high temperatures, and even strong winds.

As a result, bifacial solar panels boast extended lifespans, making them a reliable and long-lasting investment for harnessing clean energy. Their double-glass protection ensures superior durability.

Reduced Potential-induced Degradation (PID): Bifacial solar panels present a game-changing alternative to their mono-facial counterparts. The absence of a metal frame enhances their visual appeal but also mitigates the risk of potential-induced degradation (PID) for solar cells. 

With no need for grounding, these panels offer unparalleled flexibility in design, including the sleek and alluring complete glass frame. 

Impressive Aesthetics: Diverse in their designs, bifacial modules offer a plethora of options, including the elegant frameless variety. 

Renowned for their visual appeal, many enthusiasts find the complete glass frame of bifacial solar panels to be highly aesthetic, distinguishing them from their monofacial counterparts.

Works Well in Diffuse Light: In addition to their numerous benefits, bifacial solar panels hold other advantages like mono-facial counterparts: exceptional performance in diffuse light conditions. 

This remarkable feature makes them an economical choice, considering the long-term costs. The increased surface area of bifacial panels enables them to capture and convert diffuse light more effectively, ultimately reducing expenses compared to monofacial panels. 

Longer Warranties: One of the notable advantages of opting for a bifacial solar panel performance warranty period, which can stretch up to an impressive 30 years.

This extended assurance not only showcases the confidence of manufacturers in the durability and reliability of these panels but also provides peace of mind to solar energy enthusiasts. 

Low maintenance: For solar systems, maintenance is usually a breeze, and the same holds for Freyr Energy’s exceptional bifacial solar panels. With these innovative energy solutions, you can expect minimal upkeep and only periodic cleaning requirements.

Whether you’re considering solar panels for your home or any other application, the efficiency and ease of maintenance offered by bifacial solar panels make them an attractive choice.

Use of bifacial solar panels: When it comes to solar panels for home use, it’s essential to consider the advantages and limitations of bifacial panels. While they excel in generating more energy in stony, sandy, or snowy surroundings, their effectiveness on rooftops is hindered due to limited clearance for reflected light. 

Types of Bifacial Solar Panels

Different types of bifacial solar panels for home enable numerous advantages of solar energy in the following factors:

Discover the robustness of bifacial solar panels featuring double-sided glass surfaces. These structurally superior panels exhibit remarkable strength, enabling them to withstand heavy wind loads compared to their counterparts.

Balancing Weight and Cost: Glass/Transparent Backsheet

Delve into the realm of lightweight bifacial modules with a glass front side and a protective transparent back sheet. Weighing less than their glass/glass counterparts, these modules offer cost savings in transportation, labour, and tracker installations where applicable.

Market Dynamics: Trends in Glass-Glass and Glass-Transparent Backsheet Configurations 

Explore the intriguing landscape of bifacial module market shares. While glass-glass configurations dominate the market due to their proven reliability, the scarcity of glass and concerns about weight have prompted some manufacturers to shift towards glass-transparent back sheet structures. 

Bifacial Panels over Monofacial Panels

In the ever-evolving world of solar technology, advancements pave the way for progress. The question arises: will bifacial PV panels overshadow their mono-facial counterparts shortly in the context of solar panel prices in India? Before we deliver a verdict, let’s explore the differences between these two solar panel types.

  1. Polycrystalline Solar Panels: Focused on harnessing sunlight solely from the front side, these panels offer an efficiency range of 16-17%. In terms of cost, they currently stand at approximately ₹24.5 per watt solar panel price in India. However, these prices are subject to fluctuations based on various factors.
  2. Monocrystalline Solar Panels: Similar to polycrystalline panels, these mono-facial counterparts also collect sunlight from the front side only. With an efficiency range of 19-21%, they exhibit a higher performance level. However, the current cost for these panels amounts to roughly ₹29 per watt solar panel price in India.
  3. Bifacial Solar Panels: Setting a new standard, bifacial solar panels can capture sunlight from both the front and back sides. This groundbreaking feature boosts their efficiency to an impressive 22%. However, the advanced technology comes at a higher price, currently averaging around ₹28 per watt solar panel price in India.

It’s important to note that these price figures are indicative and subject to change due to various market factors. Furthermore, the performance of bifacial panels relies on the surface they are installed. 

Surprisingly, snow can enhance its efficiency, as it reflects a significant amount of light. In snowy weather conditions, bifacial solar panels have the potential to deliver even better performance.
