What are bifacial solar panels?
Solar energy has become a popular source of renewable energy, and advancements in technology have led to the development of various types of solar panels. One such innovation is the bifacial solar panel. Unlike traditional solar panels that absorb sunlight only from one side, bifacial solar panels are designed to absorb sunlight from both sides, making them more efficient in converting solar energy into electricity.
Bifacial solar panels have a transparent backsheet, which allows sunlight to pass through and be absorbed by solar cells on the front and back of the panel. This is made possible by using thin-film solar cells, which are less opaque than traditional silicon cells. As a result, bifacial solar panels can generate electricity from both direct sunlight and reflected sunlight, making them ideal for locations with high levels of diffuse light, such as cloudy or shaded areas.
These solar panels have been in existence since the 1960s, but due to their high production costs and limited efficiency, they were not widely used. However, with the recent technological advancements in the solar industry, bifacial solar panels have become more efficient and cost-effective, making them a popular choice for many solar energy projects.
Bifacial solar panels come in various sizes and shapes, similar to traditional solar panels. They can be mounted on the roof of a building or on the ground, depending on the requirements of the specific project. They are also compatible with various mounting systems, such as fixed-tilt, single-axis trackers, and dual-axis trackers, providing flexibility in installation options.
The concept of bifacial solar panels may seem complex, but the principle behind their functioning is quite simple. When the sunlight hits the front of the panel, the solar cells convert it into electricity, just like traditional solar panels. At the same time, sunlight passing through the transparent backsheet reaches the back of the panel and is reflected onto the backside solar cells. This additional sunlight contributes to the overall efficiency of the panel, generating more electricity.
Bifacial solar panels have higher efficiency compared to traditional solar panels, with some studies claiming an increase of up to 30%. This is because these panels can capture both direct and indirect sunlight, while traditional panels can only capture direct sunlight. Additionally, bifacial solar panels have a longer lifespan due to the reduced heat stress on the solar cells, resulting in less degradation over time.
Another advantage of bifacial solar panels is their lower temperature coefficient. This is the rate at which the panel’s efficiency decreases as the temperature rises. The lower the temperature coefficient, the better the panel performs in higher temperatures. Bifacial solar panels have a lower temperature coefficient compared to traditional panels, making them more suitable for hot and sunny climates.
bifacial solar panels are a significant advancement in the solar industry, offering higher efficiency, longer lifespan, and better performance in hot climates. Their ability to generate electricity from both direct and reflected sunlight makes them a suitable choice for various applications, such as commercial and residential buildings, large-scale solar farms, and even agricultural projects.

Bifacial vs. Monofacial Solar Panels
When it comes to harnessing solar energy, there are two main types of solar panels â?bifacial and monofacial. While both types serve the same purpose of converting sunlight into electricity, they differ in their design and capabilities. Understanding the differences between bifacial and monofacial solar panels can help you make an informed decision when considering solar energy for your home or business.
Monofacial solar panels, also known as traditional solar panels, are the most commonly used type of solar panels. These panels are made up of single-sided cells that collect sunlight and convert it into electricity. The cells are covered with a layer of anti-reflective coating and a sheet of glass or plastic to protect them from external elements. The energy production of monofacial solar panels depends on the amount of sunlight that hits the front surface of the panel. The back side of these panels is typically opaque, which means it does not contribute to the electricity generation process.
In contrast, bifacial solar panels have a unique design that allows them to capture sunlight from both sides, making them more efficient than monofacial panels. Bifacial panels have a transparent backsheet, which means the back side of the panel allows light to pass through it, capturing energy from the reflected sunlight. The front side of the panel is made up of traditional solar cells, while the back side consists of either monocrystalline or polycrystalline cells. Bifacial panels also have an anti-reflective coating on both sides, which further increases their efficiency by reducing the amount of sunlight that bounces off the panel.
Bifacial solar panels can be installed in two ways â?either mounted on a fixed rack or raised above the ground. When installed on a fixed rack, the panels are tilted at an angle, allowing them to capture sunlight from both sides. On the other hand, raised bifacial panels are mounted on a structure with reflectors placed underneath. These reflectors bounce sunlight from the ground onto the backside of the panel, increasing its energy production. This method is particularly useful for installations on flat or low-slope roofs, where the panels cannot be angled.
Now that we understand the basic differences between bifacial and monofacial solar panels, let’s take a look at some key factors that set them apart.
Efficiency
Bifacial solar panels are more efficient than monofacial panels due to their ability to capture energy from both sides. The efficiency of monofacial panels ranges from 15% to 20%, while bifacial panels can achieve efficiencies of up to 30%.
