They generate electricity from both directions: direct sunlight from the front and reflected light (albedo) from the back. This mechanism alone offers as high as 5–30% energy production than traditional solar panels. This means you can receive an extensive energy supply with bifacial solar panels without needing to expand the area of installation.
It is important to put up bifacial solar panels in places where lots of sunlight gets reflected for greater energy efficiency.You can improve the bifacial solar PVs’ back-side power gain by gradually increasing the surface albedo and raising the panels.
This piece highlights the albedo mechanism of bifacial solar PVs and ways we can improve their energy efficiency.
Factors Affecting Back-Side Power Gain of Bifacial Modules
There is a need for bifacial solar PVs to prove their bifaciality. Since it has the ability to generate electricity from both sides, this is a metric in bifacial solar PVs that we measure by. Bifaciality is also known as the bifacial factor or ratio, and it measures the ratio of the energy production between the back and front of the bifacial modules using Standard Testing Conditions (STC).
Here are some of the factors affecting back-side power gain of bifacial modules:
Surface/Ground Albedo
This is the most crucial factor because of the bifaciality of these solar PVs. Albedo is a measure of the reflectivity of a surface(under the solar panels). It shows a greater reflectivity, which means more sunlight rays can get to the rear cells. The typical impact of the surface albedo depends on the surface type. That will determine the gain impact of the bifacial modules.
Lighter surfaces, such as snow or sand, exhibit a high albedo and reflect more solar radiation. Darker surfaces exhibit the opposite. Surfaces with high albedo are therefore the go-to for a greater energy production of bifacial solar PVs. You can enhance it by using concrete pads, reflective materials, or white gravel.
Module Installation Height/Tilt Angle
The module installation height is also known as ground clearance. Here, rear cells of the bifacial modules need enough space to reflect light. So, the height of the module gives the rear views freedom to capture more diffuse reflected light. The higher the bifacial solar PVs, the higher the back-side gain effect. It can achieve these gains at a height of 0–1 meter, with a recommended height of 0.7–1.2 meters. Low clearance can cause self-shading and light trapping.
Tilt angle determines the amount of direct sunlight that the front side receives and the back side, reflected light.
A low tilt will see that the ground reflections don't see the rear cells, and an excessive tilt will see that the front side loses sunlight exposure. The typical tilt for bifacial solar PVs is 5–15° higher than monofacial or traditional designs.
Transmittance of Encapsulation Materials
Light transmission of bifacial modules is necessary since they generate power from both sides. Encapsulation materials are materials that enhance the transmission of light between the front and rear sides of the bifacial modules. They surround and guard the solar cells, while providing them with electrical insulation, thereby bonding the layers together. They also protect it against moisture and mechanical wear and tear.
Some of the encapsulation materials include EVA (Ethylene-vinyl acetate) and POE(polyolefin elastomer).

Optimization Strategies for Albedo Utilization
The bifaciality of bifacial modules opens it up to increased energy production. This means it is capable of enhancing its use through proper angling or orientation.
Ground-Mounted Power Plants
· Large-scale use: The bifacial solar PVs are known for their double energy efficiency. This comes in handy when it relates to a large expanse of land. It can therefore increase land efficiency through dual energy generation.
· Energy storage incorporation: Ground-mounted power plants alone generate a healthy amount of energy production. Its incorporation with other energy storage systems will further increase the energy output.
Here are some methods for improving surface albedo:
1. In snowy regions, albedo works effectively. This is thanks to its high albedo. Solar operators can utilize this by clearing the snow from the top of the solar panels and leaving it underneath.
2. Spread white gravel or smashed white stones underneath the panels. This method is cost-effective and doesn't obstruct water drainage.
3. Paint surfaces like concrete with reflective coatings or geotextiles to increase reflectivity.
Back-Side Power Gain Design of Bifacial Modules
In order for bifacial solar PVs to generate twice as much solar energy, their design features have to support them. They include the use of glass/transparent backsheet, increased mounting height, correct tilt angle, utilization of light-colored surfaces, and minimal rear-shading. The bifacial module technology supports back-side power gain by its use of a transparent backsheet or glass/glass structure for easier light penetration.
Cell spacing improvement can also help to increase back-side power gain. The greater the gap between cells, the easier light passes through. However, the gap should neither be too wide nor too small. If it's too wide, it can lead to energy loss, and if it's too small, it has a poor reflective rate of sun rays.
Its mounting design and transparency can enhance the back-side power gain as well. A higher clearance exposes the bifacial modules for proper reflection. In addition to tilt angle and row spacing, mounting structures should avoid blocking reflected light.
Calculation of Overall Power Generation Efficiency of Bifacial Modules
Unlike in monofacial or traditional solar PVs, where you calculate only one side available, bifacial solar PVs involve two. Since it produces energy from two irradiance sources, engineers assess performance by using effective irradiance and bifacial gain patterns. In bifacial modules, you earn the total power by adding the front power and rear power.
The bifacial system is a complementary system. It doesn't take away from the importance of a front-side power gain or doubles the outcome. Instead, it increases it to an extent (usually 10–30%) more than monofacial or traditional solar PVs. Bifacial solar farms now earn 20–30% annual returns, especially if they follow optimization factors.
High-albedo environments greatly benefit from bifacial systems. Sand, which has a high albedo, is used in desert environments such as the Middle East deserts or desert solar farms with an annual gain of 15–20%.
