What is a dual axis solar panel?

A dual axis solar panel is a type of solar tracker. Solar trackers are used to track the sun as it moves through the sky. Solar trackers can be split into several categories based upon the type of actuation and axis of rotation.

What is a dual axis solar tracker?

Dual axis trackers eliminate the need for monthly adjustments by using one axis to track the daily movement of the suns and another axis to track seasonal movement. The single-axis solar tracker increases solar energy efficiency by about 25%, and the dual-axis tracker by about 40%.

How much power does a dual axis solar panel generate?

A typical dual axis solar panel can generate up to 40% more electricity than a static type, but costs perhaps 100% more and has larger maintenance costs. The amount of power required to move the solar panel must be deducted from the total amount of power gained in order to accurately record the total power gain.

What is a dual-axis follow-the-Sun Solar System?

A dual-axis follow-the-sun solution for solar panels involves a system that tracks the sun’s movement in two axes (horizontal and vertical) to maximize solar energy capture.

What are the methodologies used in a dual axis solar tracking system?

In this chapter, three methodologies used in this study are discussed, namely; a meta-analysis review process of dual axis solar tracking mechanisms, the methodology used to establish efficiency of components, and lastly, the methodology used to come up with the new design.

When was dual axis solar tracking first developed?

Dual axis tracking was first developed in 1984 by Zobgi and Laplaze (Sumathi et al, 2018). Therefore, dual axis solar tracking mechanisms have been around for the past three decades. In this study the efficiency and complexity of dual tracking mechanism in the period between 1997 and 2017 is investigated.
