Bifacial Solar Panels

What Are Bifacial Solar Panels?

Bifacial solar panels have garnered immense attention and momentum in the ever-evolving world of solar technology. These remarkable panels are reshaping the way we harness solar energy by ingeniously capturing sunlight from both the front and back surfaces. Follow us as we embark on a journey into the realm of bifacial solar panels, uncovering their working principles, distinguishing features from traditional solar panels, exploring their diverse applications, and discovering why they are an intriguing option to consider.


What Are Bifacial Solar Panels?

A bifacial solar panel, as the name suggests, is a type of solar panel that can generate electricity from both sides. Bifacial solar panels employ a unique design to harness sunlight effectively. They consist of a transparent top layer, photovoltaic cells, and a specialized backsheet with a reflective surface. While conventional monofacial solar panels typically feature an opaque backsheet, bifacial solar panels are equipped with a reflective back or dual panes of glass that enable sunlight exposure to both the front and back sides of the solar cells. As a result, bifacial solar panels have a higher efficiency, as they are capable of capturing sunlight on both sides.

How Do Bifacial Solar Panels Work?

Bifacial solar panels can capture not only direct sunlight but also reflected light. Sunlight that passes through the front side of the panel is absorbed by the photovoltaic cells, converting it into electricity. Simultaneously, sunlight that hits the backside of the panel reflects off the reflective backsheet onto the photovoltaic cells, further contributing to the electricity generation.


Bifacial solar panels take full advantage of the reflected sunlight bouncing off surrounding surfaces like rooftops, the ground, or even snowy landscapes. This exceptional feature unlocks a tremendous potential for enhanced energy generation, especially in environments where reflective surfaces are prevalent. This dual absorption of sunlight significantly increases the energy output of the panel.

Applications of Bifacial Solar Panels

Bifacial solar panels are highly suitable for specific applications due to their ability to capture energy from both direct sunlight on the front side and reflected light on the backside, resulting in increased electricity generation. They are particularly well-suited for installation above large open spaces and surfaces with high reflectivity. However, their benefits may be limited in scenarios where sunlight reflection on the backside is not possible.

Here are some effective applications for bifacial solar panels:

  • Balcony Shades or Awnings

In personal or residential settings, bifacial solar panels can be integrated into balcony shades or awnings, capturing sunlight from both sides. These shading structures not only provide protection from the sun but also generate electricity. The transparent or semi-transparent backsheet design allows natural light to pass through while harvesting solar energy. Additionally, the space beneath the balcony shade or awning offers ample opportunity to capture reflected light from the surrounding balcony floor, further maximizing energy production. This combination of shading and energy generation makes bifacial solar panels an excellent choice for residential applications, offering both functionality and sustainability.

  • Solar Rooftops
Bifacial solar panels are ideal for applications on solar rooftops, offering enhanced energy generation capabilities. When installed on solar rooftops, they take advantage of direct sunlight hitting the front side and also capture reflected light from the roof surface, resulting in increased energy output. The integration of bifacial solar panels on solar rooftops offers several benefits. Firstly, it allows homeowners to generate renewable energy, reducing their reliance on the grid and lowering energy costs. Secondly, the use of bifacial panels maximizes the energy harvesting potential of the available rooftop space, allowing for greater energy production per square meter. This application is particularly advantageous in regions with ample sunlight and when combined with efficient rooftop design and solar tracking systems, further boosting energy yield.

  • Solar Awning for RV

Bifacial solar panels can be incorporated into shades or canopies for recreational vehicles (RVs), such as the Artpiece® for RV 800W. These innovative structures not only provide shade for the RV but also integrate bifacial solar panels to generate electricity. This allows RV users to harness renewable energy and power their onboard systems and appliances, even in outdoor off-grid environments. The Artpiece® for RV 800W, with its dual-sided light absorption capability, ensures efficient energy generation from both direct sunlight and reflected light, maximizing the RV's energy independence and sustainability.

  • Solar Parking Lot

Bifacial solar panels can be integrated into solar parking lot structures, such as carports or shading structures. These panels generate electricity from sunlight coming from both sides, allowing them to harness the reflected light from the ground and vehicles. Solar parking lots equipped with bifacial panels provide shade for parked vehicles while simultaneously generating renewable energy. This dual functionality makes solar parking lots an attractive solution for sustainable energy generation in commercial and public parking areas.

  • Solar Power Plants

Bifacial panels are advantageous in large-scale solar power plants. They can maximize energy output by capturing sunlight from both sides, including the reflected light from the surrounding environment. This feature is especially valuable in areas with high albedo, such as deserts or snowy regions. By utilizing both direct and reflected light, bifacial panels increase the overall energy generation capacity of the power plant, making it more efficient and economically viable.

Solar Power Plants



In a nutshell, bifacial solar panels are a game-changer in solar technology. They have the amazing ability to capture sunlight from both sides, maximizing energy production. This means more power for us! They are particularly well-suited for installation above large open spaces and surfaces with high reflectivity. Whether it's residential, commercial, or outdoor spaces like parks or parking lots, bifacial solar panels shine bright and make a significant impact.

By harnessing the power of bifacial solar panels, we can generate more clean energy and contribute to a greener future. So, let's embrace this remarkable technology and let the sun work its magic.
