Someone searching for a diy dual axis solar tracker usually wants to add motion to a small array so it follows the sun across the sky and across the seasons. This guide compares four parts that DIY builders commonly use, from a complete tracker kit to a bare controller and a linear actuator. The selection criteria are axis control (both azimuth and elevation), compatibility with 12V or 24V systems, load and weight capacity, weatherproofing, limit protection and how clearly each product is described for home builds. This is a research-based comparison of listings and specifications, not a set of bench tests.

Dual Axis Solar Tracker Controller Sun Tracker
Dual Axis Solar Tracker Controller Sun Tracker Automatic Tracking Controller System Platform Tracking, White
Best for: Builders who already have motors and want automatic control
This controller is for people who have chosen their own actuators or motors and need the logic that drives two axes toward the sun. It suits a mid-level DIYer who wants to avoid programming a microcontroller from scratch.
Key specs
- Designed as an automatic dual-axis tracking controller
- Listed for platform tracking applications
Pros
- Handles both axes in one unit
- Avoids custom firmware work for basic tracking
- Pairs with existing motor hardware
Cons
- Motors, sensors and mounting are not included, so the total build is larger
- Wiring and sensor placement still need careful planning
Bottom line: Choose this if you already own compatible motors and want a controller rather than a finished tracker.
ECO-WORTHY Solar Tracker Linear Actuator 12″
ECO-WORTHY Heavy Duty 330lbs/1500N Solar Tracker Linear Actuator Multi-Functions with Mounting Brackets (12V, 12") IP54 Waterproof 300mm Stroke Linear Motion Actuator
Best for: Lower-cost single-axis or elevation adjustment projects
A linear actuator is a common building block for tilting a panel. This one suits builders who want to adjust elevation seasonally or add one axis of tracking to a simple frame.
Key specs
- 12V DC linear actuator
- 300mm (12 inch) stroke as shown in the listing name
- IP54 rating, meaning protection against dust and water splash
- Includes mounting brackets
Pros
- Brackets included, simplifying installation
- IP54 rating suits outdoor exposure better than an unrated actuator
- Straightforward to wire into a 12V system
Cons
- A single actuator gives one axis only; full dual-axis tracking needs a second actuator and controller
- Load and speed depend on your frame, so check the rated force against panel weight
Bottom line: A sensible starting point for builders adding one axis of motion, or for elevation adjustment on a fixed-azimuth mount.
Buying Guide
Axis Configuration and Tracking Method
A true dual axis solar tracker moves in azimuth (east to west) and elevation (tilt). Confirm whether a product covers both axes or only one. Light-sensor trackers respond to the sun’s position in real time, while clock-based systems follow a calculated path. Sensor-based control handles cloud shifts better but needs clean, unshaded sensor placement.

Voltage Compatibility
Match motor and actuator voltage to your battery bank. Many small DIY trackers run on 12V, while some motors accept 24V. Mixing voltages without a proper converter can damage components.

Load Capacity and Torque
Calculate the combined weight of the panel, frame and wind loading. Motors and actuators list force or torque ratings; choose one with a comfortable margin above the expected load. Under-rated drives stall or wear quickly.

Limit Switches and Anti-Winding Protection
Panel wiring can twist as the tracker rotates. Limit switches stop travel at set points, and anti-winding protection prevents cable damage. For a continuous-rotation azimuth axis, plan a cable loop or slip ring.

Weather Resistance
Look for an IP rating on actuators and enclosures. IP54 protects against dust and splashing water but not submersion. Mount motors and controllers out of direct pooling water and use sealed connectors.

Build Effort and Use Case
Decide whether you want a finished tracker or a set of parts. Portable camping setups favor integrated kits, while fixed ground mounts can justify a custom frame built around motors and a controller.

Maintenance and Lubrication
Gears and bearings need periodic inspection. Check for play in the pivot, loose fasteners and corrosion on terminals. Owners often report that regular inspection after storms extends service life.

FAQ
What is a diy dual axis solar tracker?
It is a mount that rotates a solar panel in two directions, usually east to west and up or down, so the panel stays closer to perpendicular to the sun. Builders often combine motors or actuators with a controller and sensors.
Does a dual axis tracker add more power than a single axis tracker?
Generally, a second axis lets the panel follow seasonal changes in sun elevation as well as daily east-west movement. The added output depends on latitude, site and the control method, so expect results to vary.
Can I run a tracker from my battery bank?
Yes, many small trackers run on 12V or 24V DC. Check the motor’s current draw and confirm your battery and charge controller can supply it without dropping the system below safe charging levels.
What is the difference between a light-sensor and a clock-based tracker?
Light-sensor trackers adjust toward the brightest point, which helps with real-time corrections. Clock-based trackers calculate the sun’s path from date and time. Each has trade-offs in cloudy weather and sensor alignment.
How much wind can a tracker handle?
Manufacturers rarely give a single wind rating for DIY components. Many builders design the frame to stow flat in high wind, and some controllers include a wind-stow feature. Check your local wind loads and consult a structural professional for large installations.
Is a linear actuator enough for two axes?
No. One actuator provides one axis of motion. A dual axis build needs two actuators or motors, plus a controller that coordinates them.
Do I need a professional to install a tracker?
Basic DC wiring is within reach of many DIYers, but roof or elevated mounts, high-voltage work and structural loads call for a licensed electrician or structural engineer. Consult a professional where code or safety is involved.
Conclusion
For a complete, portable tracking setup, the REDIGOO kit is the most direct route and suits campers and RV owners. Builders who want to engineer their own frame should look at the DC pan-tilt motor set, while those who already own motors will benefit from the dual-axis controller. The ECO-WORTHY linear actuator is a practical single-axis or elevation option for a lower-cost project. Match the pick to your build effort, voltage and load, and verify ratings before you buy.
