    Advantages of bifacial panels

    ♦ Studies have shown that due to their ability to capture solar energy from both sides, bifacial panels can produce 10-20% more power than monofacial panels under the right site conditions. When single axis trackers are used, the additional power can be as high as 30-40%.

    ♦ Improved performance in terms of the levelized cost of energy (LCOE).

    ♦ These panels are particularly effective in areas with high reflectiveness such as places with light colored soils or shiny rooftops. Their ability to generate more power in a given space makes them ideal for space-constrained installations.

    ♦ Bifacial panels are typically more resistant to adverse weather conditions because of their construction. This can be confirmed by the fact that they come with longer warranties compared to traditional panels.

    ♦ Aesthetics: The transparency of the panels makes them aesthetically more appealing.
