What is dual axis solar tracking system?

To track the sun in two directions that is elevation and azimuth, a dual-axis tracking prototype is developed to capture the maximum sun rays by tracking the movement of the sun in four different directions. One axis is azimuth which allows the solar panel to move left and right.

How does a solar tracker track the sun?

PV solar trackers adjust the direction that a solar panel is facing according to the position of the Sun in the sky. By keeping the panel perpendicular to the Sun, more sunlight strikes the solar panel, less light is reflected, and more energy is absorbed. That energy can be converted into power.

Where can we use dual axis solar tracker?

Dual Axis – the tracker has two degrees of freedom and rotates on the East-West and North-South axis. This type of tracker can be used for all latitudes, but is not used for large commercial applications.

Are sun tracking solar panels worth it?

Are solar trackers worth the additional investment? In most cases, solar trackers are not worth the additional investment, even though they do produce more electricity. Because solar panels are cheaper than ever, it would cost less to install more solar panels than it would to include a tracking system.

Why do we need dual axis solar tracker?

The dual-axis solar tracker tracks the angular height position of the sun in addition to following the suns east- west movement. The dual-axis works similar to single axis but it captures the solar energy more effectively by rotating its axis along vertical and horizontal axis [1].

What is difference between single axis and dual axis solar tracker?

Solar trackers are of two types, single and dual axis trackers. Single axis trackers track in a singular way i.e. follows the Sun’s East-West or North-South movement, while Dual axis tracking has two degrees of freedom.
