Understanding the Technology Behind Solar Trackers and Dual Axis Solar Trackers

 Are you considering installing solar panels to reduce your electricity bills? If so, you may have come across the term "solar trackers" in your research. Solar trackers are devices that orient solar panels toward the sun to maximize energy production. In this article, we will delve into the technology behind solar trackers, specifically focusing on dual axis solar tracker.

What are Solar Trackers?

Solar trackers are systems that automatically orient solar panels or mirrors toward the sun to ensure they receive maximum sunlight throughout the day. By tracking the sun's movement from east to west, solar panels can produce up to 25% more energy compared to fixed-tilt systems.
There are two main types of solar trackers: single-axis and dual-axis. While single-axis trackers rotate panels along one axis, dual-axis trackers move panels along two axes to track both the sun's daily path and its seasonal incline.

How Do Dual Axis Solar Trackers Work?

dual axis solar trackers utilize sensors and motors to continuously adjust the tilt and orientation of solar panels to follow the sun's movements. By moving panels along both the azimuth (east to west) and elevation (north to south) axes, dual-axis trackers ensure that panels are always perpendicular to the sun's rays, maximizing energy capture.
The key components of a dual axis solar tracker system include:

1. Sensors: Sensors measure the sun's position relative to the panels and send signals to the control system.
2. Control System: The control system processes sensor data and activates motors to adjust the panels' orientation.
3. Motors: Motors drive the movement of solar panels along the azimuth and elevation axes to track the sun.
4. Mounting Structure: The mounting structure supports the solar panels and allows for movement along the two axes.

Benefits of Dual Axis Solar Trackers

Installing a dual axis solar tracker offers several advantages over fixed-tilt systems, including:

• Increased Energy Production: Dual-axis trackers can boost energy production by up to 45% compared to fixed-tilt systems, making them ideal for locations with limited space or high electricity costs.
• Improved Efficiency: By maximizing sunlight exposure, dual-axis trackers can generate more electricity throughout the day, increasing the overall efficiency of solar panel systems.
• Adaptability to Seasonal Changes: Dual-axis trackers can account for the sun's changing position throughout the year, ensuring optimal performance during all seasons.
