Are There Specific Geographic Areas Where Bifacial Panels Shine?

Regions with High Diffuse Light

Bifacial panels are particularly effective in areas with high diffuse light, such as mountainous regions where the sun’s rays are scattered by atmospheric particles and clouds. These regions include the Rocky Mountains in the United States, the Himalayas in Asia, and the Swiss Alps in Europe. For instance, a study found that bifacial panels in the Rocky Mountains can achieve an additional 15-20% energy gain compared to monofacial panels.

Regions with Significant Cloud Cover

Regions with significant cloud cover, such as those in the Pacific Northwest in the United States, also benefit from bifacial panels. Clouds scatter sunlight, increasing the amount of diffuse light that reaches the panels. In these regions, bifacial panels can achieve up to 20-25% more energy than monofacial panels. To optimize performance, it’s essential to ensure the panels are not shaded by trees or other obstructions, which can block the reflected light.

Specific Techniques for Maximizing Bifacial Performance

To maximize the performance of bifacial panels, it’s crucial to employ specific techniques. One technique is to use a tracker that can adjust the panel’s angle to optimize energy production, taking into account the changing sun position and cloud cover. Another technique is to use a reflective surface, such as a white or aluminum coating, to increase the amount of reflected light that reaches the panels. By employing these techniques, bifacial panels can achieve significantly higher energy yields in regions with high diffuse light or significant cloud cover.
