Single Axis Tracker – Prospects for The Future of Solar Energy


If you want to make the most of your solar project, then consider the Single Axis Tracker as your most valuable asset. Ranging from benefits like an increase in energy production to sustainability, and cost-effectiveness, it is well worth investing in this technology.
After all, the sun is a moving target; it changes its position not only daily but during the course of a year. It is vital to keep adjusting the position and angle of the solar panels in order to make optimum use of the system.
With the use of Single Axis Tracker, the panels can automatically turn towards the sun and capture maximum sunlight. The system keeps adjusting the panels every minute for maximum exposure 24/7, 365 days a year. This eliminates the need for the manual adjustment that could otherwise eat up many hours of manual labor with not even half the efficiency.

The tracking systems from Sun Action Trackers are designed to deliver superior performance and value.

In order to provide comprehensive tracking, we have linked them with our unique Real-Time Sensing (RTS) Technology. RTS operates in real-time and places our trackers at the greatest point of radiation, assisting in maximizing their ability to absorb sunlight.

In this piece, you will have a detailed look at Single Axis Trackers and how they can be of benefit to any solar power plant, whether commercial or residential.

More About Single Axis Tracker

Briefly stating, Single Axis Tracker is a technology that keeps changing the position of the solar panels in accordance with the position of the sun in the sky. The solar panels are adjusted by the tracker for the most efficient, or smallest angle of incidence, which is the angle at which sunlight hits the panel. The smaller the angle, the higher the energy production.
The Single Axis Tracker system can further be divided into two types.
  1. Active Single Axis Tracker
  2. Passive Single Axis Tracker

1. Active Single Axis Tracker

Active Single Axis Trackers use machines including motors and gears. Of course, these motors are electrically powered which can either be from the solar system itself or from another source.

2. Passive Single Axis Tracker

Passive Single Axis Tracker, contrary to motors and gears, rely on compressed fluids to shift sides when heated by the sun that tilts the panels accordingly for their tracking motion. Aside from active and passive Single Axis Trackers, there are systems that use GPS tracking to keep the panels adjusted to receive maximum sunlight at the smallest angle of incident in accordance with the latitude and longitude. Some trackers keep the panels aligned by moving them opposite to the earth’s rotation.

Number of Axis

Besides many methods of the rotation of panels, the tracking systems used in solar panels can have a different number of axis on which they move. The most popular are Single Axis Trackers that follow the movement of the sun east to west throughout the day. Other than a single axis, there is a Double axis tracking system that not only follows the movement of the sun but also moves north to west, tracking the movement of the sun over varying seasons.

However, the use of Double Axis Trackers is restricted to specific situations where space is a topic of concern. Otherwise, Single Axis Trackers are the most popular.

Benefits of Single Axis Trackers

Single Axis Trackers offer many benefits, including:

1. Better Energy Production

Using Single Axis Tracker can increase the overall energy production by 33% in comparison to fixed systems. In other words, more energy can be produced without having to increase the size of the system. Not only does it allow for more efficient use of the land but allows smaller projects to produce more energy in comparison to a bigger system with a fixed axis.

2. Economically Efficient

By adding a Single Axis Tracker system, any solar plant can be made more efficient in terms of power production, which means it can allow for a speedy recovery of the project’s cost. Solar projects can be expensive and adding a tracking system is even more so. But with the added tracking system comes the advantage of better energy production, making it economically more efficient. You can make up for the expenses in no time!

3. Sustainability

By installing a Single Axis Tracker, we can increase the sustainability of any solar project and reduce the carbon footprint. This is made possible by maximizing power generation and reducing the plant’s own reliance on the local grid.  Since the axis system needs to be powered itself (especially the Active Single Axis Tracker System), having a Single Axis Tracker can produce enough energy that the plant can become self-sustaining.

By deploying this system under the right circumstances and conditions, Single Axis Tracker can add significant value to any solar plant by increasing energy production and covering the initial costs.  Speaking of which, the Single Axis Tracker system is ideal for dry and warm locations. Locations with snow and other forms of precipitation can cause a problem for Single Axis Tracker, hence it is recommended to use them in plain terrain.

Opting for solar power plants is a green and noble initiative that will eliminate humanity’s reliance on fossil fuel and significantly reduce the emission of greenhouse gasses like CO2 along with others pollutants that are destroying our planet.

Solar power is the best alternative to fossil fuel-generated energy, and to make the best of it, we can use the Single Axis Tracker for efficient energy production. Commercial, residential, and utility-scale solar energy projects in the United States and across the world can take advantage of Sun Action Trackers‘ bankable solar energy plant solutions.
