Bifacial Solar Panels

Bifacial Solar Panels : Type, Price, Benefits

In the quest for sustainable and renewable energy sources, solar power has emerged as a shining star. Among the various advancements in  technology, bifacial solar panels have taken center stage. These innovative panels have the potential to revolutionize the solar industry by capturing sunlight not only from the front but also from the rear side, significantly increasing energy generation.

How Bifacial Panels Work?

Bifacial panels are a marvel of modern solar technology. Unlike traditional solar panels that capture sunlight only from the front side, bifacial panels have the unique ability to collect light from both the front and rear sides.

Bifacial panels work by capturing sunlight from both their front and rear sides. The front side absorbs direct sunlight through photovoltaic cells, while the rear side captures reflected and diffused sunlight, known as the albedo effect. This dual-sided absorption increases energy production, especially in environments with high reflectivity, such as snow or sand.

Type of Bifacial Panels

Various types of bifacial solar panels are available in several configurations, each with its unique features and advantages to cater to different applications and project requirements. Here are three major types of bifacial solar panels commonly used in India:

  1. Glass-Glass Bifacial Panels: These panels feature double-sided glass surfaces, offering exceptional structural strength and resistance to heavy loads. They are known for their durability and longevity.
  2. Glass-Transparent Backsheet Bifacial Panels: With a glass front side and a rear protected by a transparent backsheet, these panels provide good bifacial performance while typically being more cost-effective than glass/glass panels.
  3. Glass-Backsheet Bifacial Panels: Similar to their bifacial counterparts, these panels have a glass front side but use a non-transparent backsheet on the rear. They offer a balance between performance and cost efficiency.

How Bifacial Solar Panels Differ from Monofacial Solar Panels?

  1. Installation Variability: Bifacial panels can be installed in various configurations. They can be ground-mounted, installed on tracking systems, or even integrated into building structures, offering flexibility in design and placement.
  2. Cost: While bifacial panels may be more expensive upfront, their higher efficiency and energy output can offset the initial investment over time.

Price of Bifacial Solar Panels In India

The cost of bifacial panels can vary based on several factors, including the manufacturer, size, efficiency, and quantity purchased. On average, bifacial panels tend to be slightly more expensive than traditional monofacial panels. However, it’s essential to consider the long-term benefits and potential return on investment when assessing their price.

Some factors that can influence the price of bifacial panels include:

  1. Efficiency: Higher efficiency panels are generally more expensive, but they can generate more energy over their lifespan, potentially justifying the additional cost.
  2. Size: The physical dimensions of the panels can affect the price. Larger panels typically cost more.
  3. Installation Costs: Installation expenses, including mounting systems, wiring, and labor, should be factored into the overall price.
  4. Location: Geographic location can influence panel prices due to shipping and availability.

Benefits of Bifacial Solar Panels

Bifacial solar panels offer numerous advantages that make them an attractive option for both residential and commercial solar installations. Here are some key benefits:

  1. Environmental Benefits: Bifacial panels contribute to reduced greenhouse gas emissions and a smaller carbon footprint due to their increased efficiency.
  2. Improved Aesthetics: Bifacial panels often have a sleek, modern design and can blend seamlessly into architectural structures.
  3. Longer Lifespan: Higher-quality bifacial panels tend to have a longer lifespan and come with robust warranties.


Bifacial panels represent a significant advancement in technology, harnessing sunlight from both sides to increase energy generation. While they may have a higher initial cost, their improved efficiency, versatile installation options, and environmental benefits make them a compelling choice for those looking to invest in solar power. As the solar industry continues to evolve, panels are poised to play a crucial role in shaping a cleaner and more sustainable energy future.
