Single axis solar tracker solar power tracking system
What is a Single Axis Solar Tracker?
A single-axis solar tracker allows solar panels to move along a single axis.
Typically, these trackers are designed to follow the sun's movement in an East-West direction throughout the day.
How Does a Single Axis Tracker Work?
A single-axis solar tracker automatically adjusts the position of solar panels to follow the sun’s movement from east to west throughout the day.
By rotating around a single fixed axis—either horizontal, tilted, or vertical—it ensures that the solar modules always face the sun at the optimal angle to capture the maximum amount of sunlight.

FAQ About Single Axis Solar Tracker
1. What is a single axis solar tracker?
A single axis solar tracker is a system that rotates solar panels along one axis—typically from east to west—to follow the sun’s path throughout the day.
This helps maximize sunlight exposure and increase power generation efficiency compared to fixed mounting systems.
2. How much more energy can a single axis tracker produce compared to a fixed system?
On average, a single axis solar tracker can increase power generation by 15% to 25% , depending on local sunlight conditions and system design.
3. How does a single axis solar tracker work?
The tracker uses a motor or actuator to adjust the tilt of solar panels according to the sun’s position.
The controller may use either a time-based algorithm or light sensors to determine the best angle for maximum solar energy capture.
4. What are the main components of a single axis solar tracker?
The main components include:
* Torque tube and bearing system
* Drive motor or actuator
* Controller and sensor
* Solar mounting structure and foundations
5. Is the single axis solar tracker suitable for all terrains?
Yes, single axis trackers can be adapted for flat, sloped, or uneven terrains.
Super Solar provides customized solutions to ensure stable performance in different site conditions.
6. How long is the lifespan of a single axis solar tracker?
Typically, the system lifespan is 25 years or more, similar to solar modules.
All key components are made from durable materials such as galvanized or aluminum alloys to ensure long-term outdoor performance.
7. How to maintain a single axis solar tracker?
Maintenance is simple — only periodic inspection and lubrication of moving parts are needed.
Super Solar designs its tracking systems for low maintenance and high reliability, reducing operation costs.
8. Can the tracker be customized for different solar panel sizes or layouts?
Yes, Super Solar provides flexible tracker designs compatible with different module types and string layouts.
We can customize according to the client’s project requirements.
9. Is the single axis solar tracker resistant to strong winds?
Yes. The system is tested for wind load resistance up to 60m/s, with automatic stow function that returns panels to a safe position during storms.
10. Why choose Super Solar’s single axis tracker?
Super Solar provides:
* Optimized mechanical design for high stability
