What is a solar tracker and is it worth the investment?

Solar tracker systems are devices that are used to orient solar panels towards the sun in order to maximize the amount of sunlight they receive. These systems use sensors to detect the sun's position in the sky and adjust the angle of the panels accordingly. Solar trackers can significantly increase the amount of energy produced by solar panels, making them an attractive option for those looking to maximize their solar energy output.

However, solar trackers also come with additional costs for installation and maintenance, which raises the question of whether or not they are worth the investment. In this article, we will explore the different types of solar trackers, the benefits and drawbacks of using them and provide guidance on whether or not a solar tracker is worth the investment.

Solar tracker and its function

A solar tracker is a device that is used to orient solar panels towards the sun in order to maximize the amount of sunlight they receive. Solar trackers use sensors to detect the sun's position in the sky and adjust the angle of the panels accordingly.

By following the sun's movement throughout the day, solar trackers are able to increase the amount of energy produced by solar panels by up to 25%. There are two main types of solar trackers: single-axis and dual-axis. Single-axis trackers follow the sun's movement on a single axis (usually east-west), while dual-axis trackers follow the sun's movement on both the vertical and horizontal axis. Both types of trackers are designed to optimize the angle of the solar panels in relation to the sun's position in the sky, resulting in increased energy production.

Potential benefits of using a solar tracker

Solar trackers have the potential to significantly increase the energy production of solar panels, with some estimates indicating that they can boost output by up to 25%. In addition to increased energy production, solar trackers can also improve the overall efficiency of a solar system by reducing shading on the panels and ensuring that they are always angled towards the sun.

Furthermore, solar trackers allow for the use of smaller panel systems due to their increased output, which can save space and reduce the overall cost of a solar installation. In terms of reliability, solar trackers can be more dependable than fixed-tilt systems as they are able to adjust for changes in the sun's position and weather conditions, leading to more consistent energy production.

There are several potential benefits to using a solar tracker:

How a solar tracker works

Solar trackers are devices that are used to orient solar panels towards the sun in order to maximize the amount of sunlight they receive. There are two main types of solar trackers: single-axis and dual-axis.

The different types of solar trackers (e.g. single-axis, dual-axis)

Single-axis trackers follow the sun's movement on a single axis (usually east-west), and are typically mounted on a horizontal frame that is hinged at one end. The frame is attached to a motor that rotates the frame in the direction of the sun as it moves across the sky.

Dual-axis trackers, on the other hand, follow the sun's movement on both the vertical and horizontal axis. These trackers are typically mounted on a frame that is supported by a pair of parallel arms. The arms are connected to motors that rotate the frame in the direction of the sun as it moves across the sky.

Both types of solar trackers use sensors to detect the sun's position in the sky and adjust the angle of the panels accordingly. By following the sun's movement throughout the day, solar trackers are able to increase the amount of energy produced by solar panels by optimizing the angle of the panels in relation to the sun's position.

The mechanism by which a solar tracker follows the sun's movement

Solar trackers use sensors to detect the sun's position in the sky and adjust the angle of the panels accordingly. These sensors may be located on the tracker itself or on a separate, standalone unit.

When the sun's position is detected, the sensors send a signal to the tracker's motor(s) to adjust the angle of the panels. For single-axis trackers, this typically involves rotating the panels on a horizontal axis in the direction of the sun. For dual-axis trackers, the panels are rotated on both the vertical and horizontal axis in the direction of the sun.

The motor(s) of the solar tracker uses a gearing system to adjust the angle of the panels. This system may include gears, belts, or other mechanical components that transmit the rotational force of the motor to the panels.

Some solar trackers may also use hydraulic or pneumatic systems to adjust the angle of the panels. These systems use fluid or gas pressure to move the panels in the desired direction.
