What is Dual Axis Tracking?


The dual axis tracking refers to a solar array tracking system with two separate axes of rotation. In essence, it is a mechanical structure with additional components like motors, drives, sensors, actuators, etc.

The PV modules are placed perpendicular to the Sun by a solar tracker, which enables them to absorb more solar energy and turn it into electrical energy. To put it another way, it enables solar panels to track solar energy and pull the greatest amount of power needed to turn on electronic equipment.

In general, there are two types of solar trackers: single-axis trackers and dual-axis solar trackers. The latter tracks the Sun from all directions, including from East to West and North to South, while the former only records the Sun’s rays from east to west or north to south.

What is Dual Axis Tracker?

The East, West, North, and South angles are where the energy from the sun is collected by the dual axis trackers. They operate on the main and secondary axes. The solar tracker is assisted by two axes: one that moves it from East to West and another that moves it from North to South. As a result, they are referred to as dual-axis solar trackers.

You might be shocked to learn that dual axis trackers can produce up to 40% more electricity than stationary solar panel systems that remain in one place. A dual axis tracker is also highly flexible because it may move in all directions.

What are the Benefits of Dual Axis Tracking?

A dual axis tracker is an extremely sophisticated technology; thus, benefits are inevitable. Hence, if you’re thinking about purchasing a dual axis solar tracking system, the advantages listed below will aid in your decision-making.

  • The strongest feature of these trackers is their ability to travel in all directions, which allows them to track the Sun’s motion for longer while also supplying more energy. They don’t hold off until the sun’s rays touch the panels. Instead, during the day, the panels move in sync with the Sun.
  • These tracker doesn’t require much room to fit. It might change in a small area.
  • The dual axis solar tracking system offers additional energy in order to make up for reduced power from the grid connection.
  • These solar trackers produce up to 40% more energy than their static counterparts.
  • These trackers are best used in locations with uneven terrain or protruding stones, which make it difficult to collect enough solar energy.
  • The dual-axis solar tracker’s initial outlay will undoubtedly pay off. This implies that even though the initial investment cost of this gadget looks excessive to you, it will break even much more quickly because of the power it will produce.

What are the Limitations of Dual Axis Tracking?

The dual-axis tracking technology has some drawbacks despite its many advantages. Before purchasing, be sure to take the limitations into account.

  • The tracking system won’t perform as well as anticipated in cloudy conditions.
  • Due to the possibility of damage to its moving components, the lifespan of the dual-axis solar tracking system is short.
  • Because there are more components involved, the maintenance expense is on the higher side.
