Tracking the Sun's Movement: Understanding Dual Axis Solar Trackers

Solar energy has become an increasingly popular source of renewable energy in recent years. One way to maximize the efficiency of solar panels is to use a solar tracker, which follows the movement of the sun throughout the day to ensure that the panels are always facing directly at the sun. A dual axis solar tracker, as the name suggests, uses two axes of rotation to track the sun's movement in both the east-west and north-south directions.

How Dual Axis Solar Tracker Works

The two axes of rotation in a dual axis solar tracker allow the panels to tilt and rotate in order to follow the sun's movement throughout the day. The first axis, also known as the azimuth axis, tracks the sun's movement in the east-west direction, while the second axis, also known as the elevation axis, tracks the sun's movement in the north-south direction.

Benefits of dual axis solar tracker

The dual-axis solar tracker offers several benefits over a single-axis tracker. First, it can capture more energy from the sun, as the panels are always facing directly at the sun. Second, it can also increase the overall efficiency of the solar panels, as the panels are always at the optimal angle for capturing sunlight. Finally, it also can reduce the cost of energy, as more energy is captured from the sun per panel.

Types of dual axis solar tracker

There are two main types of dual axis solar trackers: single-row and multi-row. Single-row trackers have a single row of solar panels, while multi-row trackers have multiple rows of solar panels. Multi-row trackers are more efficient than single-row trackers, as they can capture more sunlight. However, they are also more expensive to install and maintain.

Conclusion

A dual axis solar tracker is a great way to maximize the efficiency of solar panels. It uses two axes of rotation to track the sun's movement in both the east-west and north-south directions, allowing the panels to always be facing directly at the sun. Dual axis solar trackers are more efficient than single axis trackers, they can also reduce the cost of energy, as more energy is captured from the sun per panel.
