The main advantages of using dual-axis solar trackers over fixed solar panels are:
- Higher Energy Production: Dual-axis trackers can increase solar energy output by up to about 40% compared to fixed panels. This is due to their ability to follow the sun’s path both east-west and north-south, optimizing the angle of incidence on the panels throughout the day and year.
- Accurate Solar Tracking: They rotate on both horizontal and vertical axes, allowing precise positioning of solar panels to face the sun directly at almost any time. This leads to a consistently maximized solar irradiance capture regardless of the time of day or season.
- Seasonal Adaptability: Dual-axis trackers adapt well to seasonal variations, especially in high-latitude regions where the sun’s elevation changes significantly between summer and winter. This adaptability ensures steady and reliable energy production year-round.
- Flexibility in Panel Orientation: The dual-axis movement allows the panels to be oriented in nearly any direction, which is useful to maximize energy yield in sites with challenging sun paths.
In summary, dual-axis trackers significantly boost the efficiency and energy yield of solar installations by maintaining optimal panel alignment with the sun throughout the day and across seasons, outperforming fixed solar panels by as much as 40% in energy generation.
