What Are Bifacial Solar Panels?
Bifacial solar panels are a relatively new type of photovoltaic (PV) panel technology that offer higher efficiency than the traditional monofacial (single-sided) solar module. They have two surfaces, or faces, that are typically aligned to absorb light from both the front and back. Bifacial solar cells are made from the same materials as monofacial solar cells, such as silicon, but the cells are mounted differently. The back side of the cells is exposed to light, allowing for additional solar energy absorption. Therefore, bifacial solar panels can produce more electricity than monofacial solar panels.
The main advantage of bifacial solar panels is their increased efficiency. By capturing light on both sides of the module, bifacial panels can generate more energy in the same amount of time and area than a monofacial panel. Bifacial solar panels are also more resilient than their monofacial counterparts, since they can withstand higher wind speeds and debris without damage. Additionally, bifacial solar panels are less prone to shadowing losses caused by tree branches or nearby buildings than monofacial panels.
The increased efficiency of bifacial solar panels comes with a cost. Bifacial solar panels are more expensive than monofacial panels because they must be specially manufactured. The module also requires additional mounting hardware to ensure the cells are positioned correctly. In addition, the extra cost of labor to install bifacial solar panels may be a factor in the decision to switch from monofacial to bifacial systems.
For those looking to maximize their solar energy generation, bifacial solar panels may be worth the additional expense. Bifacial solar panels are proven to be a reliable and efficient way to generate more solar energy than traditional monofacial panels. Therefore, if the costs can be justified, bifacial solar panels are an excellent choice for those looking to reduce their energy bills and move toward a more sustainable future.

Bifacial Solar Panels for Commercial and Utility-Scale Applications
Bifacial solar panels are gaining traction in commercial and utility-scale applications due to their ability to generate more electricity from the same amount of solar radiation. By using both sides of the panel, bifacial panels can increase overall system efficiency by up to 11%. The technology is based on the fact that the front of a bifacial panel can capture direct sunlight, while the backside can absorb reflected light from the ground or adjacent surfaces, such as rooftops or white-covered roofs. To maximize the efficiency of these panels, they are typically installed in some of the following ways:
Single Axis Tracking: In this setup, the bifacial panels are mounted on a single axis system that tracks the sun throughout the day, allowing the backside of the panel to receive direct sunlight at certain times during the day. This technique is a cost-effective way to increase the overall energy output of a system.
Directional Tracking: A directional tracking system allows for the bifacial panels to move in two directions, horizontally and vertically. This allows the backside of the panel to always receive direct sunlight and ensures maximum power generation.
Ground Mounted: Ground mounted bifacial systems can take advantage of naturally reflective surfaces, such as snow-covered rooftops, to further increase their efficiency. This technology is especially useful in locations with little space for rooftop installations.
In addition to the increased efficiency, bifacial systems can also provide additional benefits, such as improved module aesthetics, better shade immunity, and fewer energy losses due to shading. Bifacial solar panels are a great option for commercial and utility-scale applications that require a high level of efficiency and energy output.
How Much More Energy Can Bifacial Solar Panels Generate?
Bifacial solar panels have the potential to generate significantly more energy than standard monofacial solar panels. Bifacial solar panels are capable of generating energy from both sides of the panel, meaning that they capture light reflected off the ground and other nearby surfaces. This means that bifacial solar panels can capture energy from two sides -- the front and the back -- with the back side receiving up to 30 % more energy. This allows bifacial solar panels to generate up to 30 % more energy than a mono-facial solar panel, depending on the environment and orientation.
The amount of energy gained from the backside of bifacial solar panels is dependent on the reflectivity of the underlying surface. A darker surface with a low albedo—the amount of solar energy reflected from a surface—will absorb much of the reflected light and reduce the energy yield from the backside of the panel. Conversely, a bright and reflective surface will increase the energy yield from the backside of the bifacial solar panel. Any environment with snow, concrete, or light colored soil will be ideal for bifacial solar panels, as these surfaces can reflect up to 80-90% of the sun’s energy back up towards the panel.
A variety of factors can affect the energy generation of bifacial solar panels. These include the angle of the panel, the latitude where the solar panel is installed, the albedo of the underlying surface, the height of the panel, and the amount of shading from nearby objects. All of these factors will influence the output of the bifacial solar panel, so it is important to consider these when selecting a solar panel for installation.
In some cases, bifacial solar panels can generate up to 30% more energy than monofacial solar panels. However, they also come with higher installation and maintenance costs. Despite the cost, many solar companies are beginning to install bifacial solar panels, due to their increased energy efficiency and potential for higher returns on investments. Ultimately, the decision of whether bifacial solar panels are worth the cost will depend on the individual’s situation and the specific environment in which the panel is installed.
How are bifacial modules installed?

They are usually mounted in a frame, where they are held in place by either bolts or nuts and screws, depending on the specific type of module. Depending on the roof or ground characteristics, the modules can also be installed without frames in some cases.
When installing bifacial modules, it is important to take into account the local environment, including the amount of sun that the modules will be receiving. It is also important to ensure that the modules are not placed in shaded areas or locations where they will be affected by other external factors. This is why it is essential to plan the installation of the modules in such a way that ensures that they are able to take full advantage of the sun’s energy.
In addition, bifacial modules need to be securely mounted so that they don’t move or vibrate in strong winds and other conditions. This is why it is important to use a mounting system that is designed to securely attach the modules to the roof or ground. It is also important to install the modules in such a way that they are not exposed to any potentially damaging weather conditions.
it is also important to note that it may be necessary to use additional components when installing bifacial modules. For example, it is often necessary to use isolation devices, such as junction boxes or surge arresters, to protect the modules from electrical damage due to surges in the power grid. It is also important to use cables and clamps to ensure a secure connection between the modules and the racking system.
bifacial modules are a great way to reduce energy costs and boost the efficiency of a solar energy system. When installing these modules, it is important to take into account the local environment, mount them securely, and use additional components as needed. By taking these steps, homeowners and business owners can ensure that their bifacial modules are properly installed and reap the rewards of increased energy efficiency.
