How do Bifacial Solar Panels Work?
Bifacial solar panels operate on the same fundamental principles as traditional solar panels, converting sunlight into electricity through the photovoltaic effect. When sunlight strikes the solar cells, it excites electrons, generating a flow of electricity. However, what sets bifacial panels apart is their ability to capture sunlight from both the front and rear sides.
This is particularly effective in environments where light can be reflected, such as snowy or sandy areas. The efficiency of bifacial panels is further enhanced by their design. The transparent back allows for light to penetrate and reach the solar cells on the rear side, which can capture additional energy that would otherwise go unused.
The amount of additional energy generated depends on various factors, including the albedo effect of the ground surface—how much light is reflected—and the angle of installation. By optimizing these conditions, you can maximize the energy output of bifacial solar panels.
Advantages of Bifacial Solar Panels
One of the most significant advantages of bifacial solar panels is their increased energy production potential.
