Quick Answer
Dual-axis tracking is beneficial for bifacial solar panels due to their ability to optimize energy production from both front and rear sides, resulting in increased overall efficiency and power output.
Maximizing Bifacial Energy Yield
Dual-axis tracking allows bifacial solar panels to capture reflected light from the ground and surrounding surfaces, increasing energy production by up to 25%. This is achieved through the panel’s ability to track the sun’s movement in two axes, ensuring optimal exposure to both direct and diffuse sunlight.
Technical Requirements for Dual-Axis Tracking
To take full advantage of dual-axis tracking with bifacial solar panels, a system with high positional accuracy and speed is required. Typical specifications include a maximum tilt angle of 90 degrees, a rotation speed of 0.5-1.5° per second, and a positional accuracy of 0.1°. These technical requirements enable the system to accurately track the sun’s movement and adjust the panel’s angle to optimize energy production.
Economic Benefits for Large-Scale Installations
In large-scale solar installations, dual-axis tracking with bifacial solar panels can lead to significant economic benefits. By increasing energy production and reducing the required land area, system owners can achieve higher returns on investment and lower land acquisition costs. Additionally, the increased efficiency and power output can enable the use of smaller inverters and reduced cabling, further reducing overall system costs.
