On the other hand, bifacial panels have cells on both the front and back sides, making them more efficient in capturing sunlight.

How Do Bifacial Panels Generate Electricity?

The basic principle behind the working of bifacial solar panels is the same as traditional solar panels. When sunlight reaches the surface of the panel, the photons (particles of sunlight) are absorbed by the cells on the front or rear side. These cells have a semiconductor material, usually silicon, that converts the energy from the photons into electricity. This electricity is then collected by metal contacts on the top and bottom of the cells, which are then connected to wires that transfer the electricity to the electrical grid.
The main difference between the working of traditional and bifacial panels is that the back layer of cells in bifacial panels can also absorb sunlight. This is made possible by the use of transparent materials such as glass or plastic on the top and bottom layers of the panel. The sunlight that passes through the front layer of cells and reaches the back layer can be converted into electricity by the cells on the back. This makes bifacial panels more efficient, as they can utilize both direct sunlight and reflected sunlight.

The Benefits of Bifacial Solar Panels

Bifacial solar panels have several advantages over traditional solar panels. The most significant advantage is their higher efficiency in converting sunlight into electricity. Due to their ability to capture sunlight from both sides, bifacial panels can generate more electricity than traditional panels, making them a cost-effective option for solar energy.
Moreover, unlike traditional panels, bifacial panels are not affected by shading. This means that even if part of the panel is under shade, the cells on the other side can still generate electricity. This is especially beneficial in areas with inconsistent weather, as the panels can still generate energy even on cloudy days.
Furthermore, bifacial panels have a longer lifespan compared to traditional panels. The use of protective materials on both sides of the panel helps prevent damage and deterioration, leading to a longer lifespan. Additionally, these panels are also more resistant to extreme weather conditions such as high winds and heavy rain, making them a durable option for solar energy production.
