A solar bifacial + tracking system includes a tracker that tracks the sun throughout the day, as well as reflective panels or sheets that direct additional sunlight onto the PV cells. This can increase the power output of the cells by up to 30%. For a more detailed explanation of solar bifacial + tracking systems, please read the following.

How Do Solar Bifacial Modules Work?

Bifacial solar panels, which are made with high-efficiency solar cells on both sides of the panel and generate electricity simultaneously, are the most recent technology. They can absorb light from both the front and rear sides, allowing for diffused light to be used. Solar panels for bifacial use high-watt modules as well as high-efficiency panels for cell development and solar panels. Traditional opaque-back sheeted panels are monofacial.

The solar bifacial module is made of thin layers of silicon solar cells that are located on the front and back sides of the module. The solar cells on the front generate electricity from sunlight, while the solar cells on the back collect sunlight that has been reflected off the ground and other objects.  This allows the solar cells to collect more photons, which leads to higher power output.

Some bifacial module producers claim that a bifacial module can be installed on a reflective surface such as a white TPO roof, or on the ground with a light-colored stone. This is because the additional power generated from the rear of the module produces up to 30% more power.

Bifacial solar panels offer many advantages over monofacial ones, such as higher energy output, greater durability, and lower installation costs. Moreover, bifacial panels absorb more sunlight and thus help reduce the effect of greenhouse gases and protect the environment and ecosystem.

According to Market Research Future’s report, during the forecast period 2022-2030, the global bifacial solar market growth rate is expected to reach 16.82% CAGR.

How Do Solar Tracking Systems Work? 

Solar tracking systems are devices that keep solar panels pointing at the sun while it moves across the sky. A solar tracking system adjusts the face of the solar panel or reflective surfaces to align with the sun.  To maximize the efficiency of solar panels, they must be pointed at the Sun. Tracking systems can help increase their output.

There are many types of solar tracking systems. The most popular type is the single-axis tracker. This tracker tracks the sun along one axis, usually from east to west. These trackers are cheaper than others and easier to maintain.

A dual-axis solar tracker is another type. This tracker can track the sun with greater precision than a single-axis one. It has two axes. These trackers can boost a solar panel’s output by up to 30%.

Active and passive solar tracking systems are available. Active solar tracking systems use sensors that adjust the angle of solar panels to match the sun’s position. Active solar tracking systems use motors to move the panels in order to follow the sun throughout the day.

The global Solar Tracker Market was valued at USD 3.38 billion in 2021 and is projected to reach USD 21.15 billion by 2030 at a CAGR of 20.13% from 2022 to 2030.

Solar Bifacial + Tracking Systems

Solar Bifacial + Tracking systems track the sun and tilt the modules to maximize sunlight exposure. A system that uses bifacial panels and a solar tracker generates 30 % more solar energy than one that uses traditional panels.  These systems are also more efficient than fixed-mount solar arrays because they capture more energy.

Also, these systems are able to increase the energy output of large-scale solar farms because they absorb more energy on both sides.

Conclusion:

Solar energy is a significant source of renewable energy. The production costs of solar energy power plants are lower than those of other energy sources. This makes it the energy source for the future. One of the greatest disadvantages of solar energy is the inability to generate solar energy during cloudy weather conditions. The solar irradiance values can also vary significantly between winter and summer months.

To maximize solar energy efficiency, it is important to track the sun throughout the day (east/west) and all year (north/south). It is also important to capture the maximum amount of sunlight. Solar tracking systems and solar bifacial modules are key devices that can be developed and used for this purpose. These systems have been the subject of numerous research in recent years that will allow us to reap the benefits of solar energy. Many theoretical and experimental types of research have been conducted on tracking systems and solar modules. They include analysis, simulation, modeling, designing, fabrication, performance, and efficiency.
