Quick Answer
To choose the right mounting system for bifacial panels, consider the panel's weight, size, and frame type, as well as the slope and orientation of the installation site. The mounting system should accommodate the extra weight of bifacial panels and ensure optimal exposure to both front and rear surfaces.
Assessing Mounting Requirements
When selecting a mounting system for bifacial panels, it’s essential to evaluate the panel’s weight and size. Standard bifacial panels can weigh between 18 and 22 pounds per square foot, which is significantly higher than traditional monofacial panels. Consider a mounting system with a sturdy frame and reinforced brackets to handle the additional weight. A good rule of thumb is to choose a mounting system that can support at least 20 pounds per square foot.
Factors Influencing Mounting System Selection
The slope and orientation of the installation site also play a crucial role in selecting the right mounting system. Bifacial panels work best when installed at a slope between 15 and 40 degrees, which allows for optimal exposure to both front and rear surfaces. If the installation site has a steeper slope, consider a mounting system with adjustable tilt and pitch to ensure optimal performance.
System-Specific Considerations
When choosing a bifacial panel mounting system, consider the following system-specific factors:
- Ensure the mounting system is compatible with your bifacial panel’s frame type (e.g., frameless or framed).
- Choose a system with minimal shading and obstructions, which can negatively impact bifacial panel performance.
- Consider a system with adjustable mounting points to accommodate different panel sizes and arrangements.
- Consult the manufacturer’s guidelines for recommended mounting systems and installation techniques.
