Are There Specific Mounting Structures for Bifacial Panels on Ground?

Ground Mount Design for Bifacial Panels

When it comes to ground mounts, bifacial panels require a unique approach to maximize energy production. One popular option is the adjustable tracking system, which allows for a 30-degree tilt to optimize energy production. For example, the Solaria PowerXT system uses a 30° angle to increase energy production by up to 25%. Additionally, using a ballasted mount with a wide footprint can help to distribute the weight evenly and prevent movement due to wind or other external factors.

Mounting Structure Considerations

When selecting a mounting structure for bifacial panels, it’s essential to consider the panel’s size and weight, as well as the ground’s load-bearing capacity. A typical bifacial panel can weigh between 14-20 kg/m², so a sturdy mounting system is crucial. For example, a commercial-grade ground mount designed for bifacial panels would typically use a steel frame with a 600 mm x 600 mm base plate and a 400 mm x 400 mm corner plate. The mounting system should also be able to withstand wind loads of up to 2,200 Pa and snow loads of up to 500 kg/m².

Bifacial Panel Mounting Techniques

To ensure optimal energy production from bifacial panels, it’s essential to follow proper installation techniques. When installing bifacial panels on a ground mount, ensure that the panels are mounted at least 250 mm above the ground to prevent shading from the ground. Additionally, use a reflective layer or a white backing to enhance the reflective properties of the surface beneath the panels, which can increase energy production by up to 10%.
