What Are Bifacial Solar Panels

What Are Bifacial Solar Panels

The search of more efficient and long-lasting energy sources has made solar energy a significant player. Solar panels are usually mounted on rooftops or in solar farms to collect sunlight and generate electricity.

Bifacial solar panels are one of the most intriguing technological advancements of the last few years, yet the area of solar technology is continually evolving.

These solar panels are revolutionary to enhance solar energy in this technical evolving world by capturing the sun energy from both of its faces. This article will explore the bifacial solar panels and their benefits in enhancing solar power.

What are Bifacial Solar Panels?

An advanced development in solar technology is bifacial solar panels that are separate from traditional solar panels with respect to their distinctive shape. The word “bifacial” explains the ability to absorb sun energy from its both the front and back surfaces, significantly growing their capacity to collect solar energy.

Their ability to get the sunlight on both surfaces make these solar panels very special. Unlike traditional solar panels, that can only produce electricity when openly exposed to sun on one side, while bifacial solar panels are able to gather sunlight reflected off adjacent planes. The innovative dual-sided structure of bifacial solar panels make them more proficient than conventional single-sided solar panels by increasing their sunlight absorption.

These panels work exceptionally well in areas with plenty of reflected sunshine, such as parking lots or open fields. In addition, they work well in scenarios like ground-mounted solar systems, where solar panels are not anchored to roofs directly.

How Bifacial Solar Panels Work

Sunlight is converted into electrical energy by Bifacial solar panels. The solar cells in the panel capture sunlight and transform it into electrical power when it touches the front surface. In addition to being turned into energy, sunlight that strikes the panel’s rear surface is reflected into the solar cells.

The total amount of energy produced from the rear of a bifacial solar panel depends on several parameters, including the reflecting material used, the panel’s orientation and the amount of sunlight reflected. The design of bifacial solar panels and the materials used significantly affect their effectiveness. This is how they work:

  1. Front-side Absorption: Bifacial solar panels have photovoltaic cells on their front side, much as conventional solar panels. Like regular panels, these cells collect direct sunlight and use the photovoltaic effect to turn it into energy.
  2. Rear-side Reflection: The highly reflecting substance that covers the back of a bifacial panel is what makes it unique. This material reflects sunlight back to back of the panel from the ground or other close surfaces. The reflected sunlight is successively absorbed in a second phase and converted into energy.
  3. Enhanced Efficiency: Due to its ability to absorb sunlight from both directions, bifacial solar panels have ability to produce more electricity from the same amount of sunlight. Since this boosts their efficiency, a variety of applications will find them appealing.

Advantages of Bifacial Solar Panels

  • Enhanced Energy Production: Bifacial solar panels have the ability to generate up to 20% more electricity than traditional solar panels, depending on installation and climatic conditions. The expected increase in energy output might result in a significant ROI for solar plants.
  • Versatility: Bifacial panels may be installed in a range of configurations, including elevated structures and ground-mounted arrays, to maximize their performance. Their adaptability makes them suitable for both home and business purposes.
  • LCOE: Bifacial panels’ better efficiency may result in a reduced LCOE over time, which would increase the long-term cost-effectiveness of solar energy.
  • Environmental Benefits: By generating more clean energy from the same quantity of sunshine, bifacial solar panels significantly reduce greenhouse gas emissions. This makes a substantial contribution to international efforts to combat climate change and lessen our dependency on fossil fuels.
  • Better Aesthetics: Bifacial panels may seem sleek and contemporary because of their transparency, which makes them a visually desirable option for residential installations.
  • Enhanced efficiency: Compared to traditional solar panels, bifacial solar panels may attain up to 20% greater efficiency levels.
  • Greater variety of uses: When compared to conventional solar panels, bifacial solar panels have a greater range of uses. They work well in areas like parking lots and wide fields where there is a lot of reflected sunlight. They are also excellent for ground-mounted solar systems.
  • Reduced cost: Bifacial solar panels are becoming less expensive with time. Bifacial solar panels are become more and more appealing to solar installers as their cost keeps going down.

Disadvantages of Bifacial Solar Panels

The use of bifacial solar panels has several limitations. Among these drawbacks are:

  • Higher initial cost: Bifacial solar panels have a greater initial cost than conventional solar panels. Nevertheless, the greater initial investment is compensated for by the bifacial solar panels’ improved efficiency.
  • Increased complexity: Compared to conventional solar panels, bifurcating solar panels need additional installation work. This is due to the fact that the panel’s reflective backing may make it challenging to connect the panel to the mounting mechanism.
  • Decreased efficiency in darkened locations: Compared to conventional solar panels, bifacial solar panels may perform less well in shaded situations. This is so that sunlight may be reflected off the solar cells by the reflective material on the panel’s back.


Bifacial solar panels are evidence of the constant advancements in solar technology. Energy capture efficiency has undergone a paradigm shift due to its dual-sided design, which captures sunlight from both the front and rear surfaces.

Bifacial solar panels offer a way to improve sustainability, efficiency, and long-term cost savings as we embrace the bright future of solar energy. Leveraging the sun’s infinite energy can be accomplished to unprecedented levels of innovation and quality when you work with Just Doing Solar as your partner.
