What are bifacial solar panel?

Bifacial solar panels are a type of photovoltaic module that can capture sunlight from both the front and rear sides of the panel. Unliketraditional solar panels that only utilize sunlight from the front side, bifacial panels have a transparent backsheet that allows sunlight to passthrough and be reflected onto the rear surface of the solar cells, This design enables them to generate electricity from both direct sunlightand reflected sunlight,typically from surfaces such as the ground or nearby structures.

Key features of bifacial solar panels include:

Double-sided Absorption: Bifacial panels have solar cells on both the front and back sides. This allows them to capture sunlight that isreflected off surfaces, such as the ground or nearby structures, in addition to direct sunlight.

Transparent Backsheet The backsheet of bifacial panels is made of transparent or translucent material, allowing sunlightto penetratethrough to the rear side of the solar cells.

Albedo Effect: The albedo effect refers to the reflection of sunlight off surfaces, and bifacial panels leverage this effect to generateadditional electricity. The reflected sunlight increases the overall energy yield of the panel.

Increased Energy Yield: Bifacial solar panels have the potential to achieve a higher energy yield compared to traditional monofacial panels

especially in environments with high albedo (high reflectivity) surfaces, such as snowy landscapes or areas with ight-colored surfacesVersatilty in Installation: Bifacial panels can be installed in various configurations, including ground-mounted systems, building-integratedinstallations, or raised installations to allow light to reach the rear side of the panels.

While bifacial solar panels offer advantages in terms of increased energy capture, thoir performance is infiuenced by factors such as thealledo of the surrounding surfaces, the til and height of the panels, and the overall system design.Bifacialtechnology is evolving, andongoing research and development aim to optimize their efficiency and cost-effectiveness
