Bifacial Solar Panel Efficiency

Understanding Bifacial Solar Panels

Bifacial solar panels are a game-changer in solar energy. Unlike traditional monofacial panels that only absorb sunlight from one direction, bifacial panels can generate electricity from both the front and back surfaces.

This is due to the ability to capture reflected light from surrounding surfaces like roofs, ground, or even snow.

Key Advantages

• Increased Energy Yield: Up to 30% higher energy yield compared to monofacial panels.
• Reduced Hot Spots: Better heat dissipation improves panel lifespan.
• Suitable for Various Installations: Ideal for rooftop, ground-mounted, and floating solar projects.

How Bifacial Panels Work

The key to bifacial panel efficiency is reflection. When sunlight hits the rear surface of the panel, it's reflected back into the cells. These photons then generate electricity, effectively doubling the amount of sunlight converted into power.

The color and reflectivity of the mounting surface play a crucial role. Darker surfaces reflect more light back into the panel.

Factors Affecting Performance

• Ground Reflectance: The reflectivity of the ground surface is the most significant factor.
• Panel Tilt and Orientation: Optimal tilt angle maximizes reflection.
• Panel Spacing: Adequate spacing allows for maximum light reflection.
