Bifacial solar modules are a type of photovoltaic (PV) module designed to capture sunlight from both the front and rear sides, increasing energy generation efficiency. Traditional solar panels only utilize the front side to convert sunlight into electricity, but bifacial modules feature a transparent backsheet, allowing sunlight to be reflected onto the rear surface. This rear-side exposure enables the modules to capture additional sunlight reflected from surrounding surfaces, such as the ground or nearby structures.

1. WHAT ARE
BIFACIAL SOLAR
MODULES?

2. A bifacial solar module is a type of photovoltaic (PV) module designed to capture
sunlight from both the front and rear sides, increasing overall energy production.
Traditional solar panels capture sunlight only from the front side, where the solar
cells are located. In contrast, bifacial modules have solar cells on both the front and
back surfaces, allowing them to generate electricity by capturing sunlight that is
reflected off surrounding surfaces, such as the ground or nearby structures.
Bifacial solar modules typically have a transparent backsheet or a glass backsheet
on the rear side to allow sunlight to reach the rear cells. The reflected light from the
ground or other surfaces can contribute to the overall energy output of the
module. This design can be particularly beneficial in certain environments, such as
those with high albedo (reflectivity) surfaces like snow or sand.
The performance of bifacial solar modules depends on factors such as the type of
reflective surfaces, the angle of sunlight, and the module's mounting configuration.
Bifacial technology is continuously evolving, and research and development efforts
aim to enhance the efficiency and cost-effectiveness of these modules.

4. Bifacial solar modules are designed to capture sunlight from both the front and rear sides, increasing energy production
compared to traditional monofacial modules. Installing bifacial modules requires some specific considerations to maximize
their efficiency. Here's a general guide on how bifacial modules are installed:
1. Mounting Structure: Bifacial modules are usually installed on a mounting structure that allows sunlight to reach both the
front and rear sides. The mounting structure should be designed to optimize the reflection of sunlight onto the rear side of
the modules. Ground-mounted installations are common for bifacial modules.
2. Ground Cover: The ground cover or surface underneath the modules plays a crucial role. Ideally, it should be reflective to
enhance the amount of sunlight reaching the rear side of the modules. Options include light-colored gravel, grass, or even
reflective materials designed for this purpose.
3. Tilt Angle and Height: Adjust the tilt angle and height of the modules based on the specific site conditions and the desired
energy output. The optimal tilt angle may vary depending on factors such as latitude, time of year, and local climate
conditions.
4. Spacing: Proper spacing between the bifacial solar modules is important to avoid shading and maximize light exposure.
The spacing should allow sunlight to reach the rear side of each module without interference from neighboring modules.

5. 5. Orientation: Consider the orientation of the modules to maximize energy capture. This involves aligning the modules to
face the direction that receives the most sunlight throughout the day.
6. Cleaning and Maintenance: Keep the modules clean to ensure maximum light penetration. Since the rear side is exposed
to the ground, it may accumulate dirt and debris more quickly than the front side. Regular cleaning is essential for optimal
performance.
7. Electrical Configuration: Ensure that the electrical wiring and configuration are suitable for bifacial modules. Some
installations may require adjustments to the wiring and inverters to accommodate the unique characteristics of bifacial
technology.
8. Monitoring and Optimization: Implement a monitoring system to track the performance of the bifacial modules. This can
help identify any issues and optimize the system for better energy production.
It's important to note that the installation process may vary based on the manufacturer's specifications, the specific design of
the bifacial modules, and the characteristics of the installation site. Always refer to the manufacturer's guidelines and consult
with solar professionals to ensure the proper installation of bifacial modules for your specific project.

8. Bifacial solar panels can generate up to 30% more energy compared to monofacial panels. However, the
actual increase in energy production can vary based on the specific installation site and design. For
example, a site with high reflectivity, such as snow-covered ground or a light-colored surface, can
enhance the performance of bifacial panels.

9. Bifacial solar panels work best when they lie around four metres from the ground. This is because
the higher up the panel sits, the more light is able to get underneath them. For this reason bifacial
solar panels are unlikely to suit a residential setting, but work well in solar farms, off-grid systems,
or commercially.
