What Are Bifacial Solar Panels?

Bifacial solar panels are an advanced type of photovoltaic technology designed to capture sunlight on both their front and rear sides, increasing their overall energy generation. Unlike traditional solar panels that only harvest light from one side, bifacial panels have a transparent backsheet or are dual-glass, allowing reflected light from surfaces such as the ground, rooftops, or surrounding structures to reach the rear side of the cells.

  1. Bifacial solar panels are an advanced type of photovoltaic technology designed to capture sunlight on both their front and rear sides, increasing their overall energy generation. Unlike traditional solar panels that only harvest light from one side, bifacial panels have a transparent backsheet or are dual-glass, allowing reflected light from surfaces such as the ground, rooftops, or surrounding structures to reach the rear side of the cells. This dual-sided absorption boosts the efficiency of the panels, especially in environments with high albedo, or reflectivity. Bifacial panels are often mounted on elevated structures or tracking systems to maximize their exposure to sunlight from different angles throughout the day. This innovative design makes them particularly effective in open fields, snowy regions, or areas with light-colored surfaces that reflect a significant amount of light.

  3. Higher Energy Yield: By capturing additional reflected and diffused light on the rear side, bifacial solar panels can increase the overall energy yield. The gain can range from 10% to 30% more energy production, depending on the installation environment and conditions. Better Performance in Various Conditions: Bifacial solar panels perform well in snowy, sandy, or other high-albedo environments where a significant amount of light is reflected back onto the rear side of the panel. Durability: The double-glass construction often used in bifacial panels enhances their durability and resistance to environmental stresses like moisture and extreme temperatures. Reduced Land Use: With higher energy output per panel, bifacial panels can reduce the amount of land needed for solar installations, which is particularly advantageous in space-constrained environments.

  4. Bifacial and monofacial solar panels are two types of photovoltaic technologies with distinct characteristics and applications. Bifacial solar panels have photovoltaic cells on both sides, allowing them to capture sunlight from both the front and rear, resulting in up to 10-30% higher energy yield, especially in environments with reflective surfaces like snow or sand. This design often includes a transparent backing, enhancing their durability but also increasing their cost and installation complexity. In contrast, monofacial panels have cells on only one side with an opaque backing, making them simpler and cheaper to install while being widely available for standard rooftop and ground- mounted setups. Although they offer lower energy output compared to bifacial panels, their cost-effectiveness and ease of installation make them a popular choice for residential and many commercial solar projects.
