Is It Feasible to Mount Bifacial Panels Vertically for Better Light Capture?

Technical Considerations

When mounting bifacial panels vertically, the rear reflectance of the ground or surface beneath the panel is increased, allowing for additional energy production. However, the panel’s angle and orientation must be optimized to maximize the reflected light entering the panel. Studies have shown that panels mounted at a 30-degree angle can achieve up to 25% more energy production than those mounted horizontally.

Structural Integrity and Safety

To ensure structural integrity and safety, vertically mounted panels must be securely fastened to a sturdy frame, taking into account the wind load and weight of the panels. A minimum of 2.5 inches of clearance between the panels and the ground or surface is recommended to prevent damage from debris or water accumulation. Additionally, regular inspections and maintenance are crucial to ensure the stability and performance of the vertically mounted panels.

Practical Applications and Limitations

Vertically mounted bifacial panels are particularly suitable for areas with limited space, such as rooftops or building facades. However, their installation can be more complex and may require additional hardware and labor costs. It is essential to assess the site conditions, panel type, and local building codes before installing vertically mounted bifacial panels. A thorough analysis of the potential benefits and limitations will help determine the feasibility and optimal design for a specific application.
