Quick Answer
Bifacial panels do not require specialized mounting hardware, but they do require a specific distance between the panels and the ground to maximize energy gain from rear-side irradiance.
Bifacial Panel Mounting Requirements
Bifacial panels can generate electricity from both the front and rear sides, increasing energy output by up to 25%. However, to maximize this benefit, mounting hardware must be carefully selected to ensure a minimum distance between the panels and the ground. This distance, also known as the “air gap,” should be at least 10% of the panel’s height to allow for rear-side irradiance.
Common Mounting Hardware for Bifacial Panels
While bifacial panels don’t require specialized mounting hardware, the use of a tracking system can enhance energy output. A single-axis tracking system can increase energy production by up to 45%, while a dual-axis system can increase it by up to 50%. When choosing a mounting system, consider the terrain, wind resistance, and snow load to ensure the system’s stability and longevity.
Installation Tips for Bifacial Panels
When installing bifacial panels, it’s essential to follow the manufacturer’s instructions for the recommended air gap and tilt angle. A tilt angle of 15-20 degrees can optimize energy production. Additionally, ensure that the panels are properly secured to the mounting hardware to prevent damage from wind or snow. By following these guidelines, you can maximize the energy output of your bifacial panel system.
