Crafting a Solar Stand or Sun Tracker isn't just a DIY project – it's an initiative to significantly boost the efficiency of your solar panels by harnessing the maximum amount of sunlight throughout the day. The purpose of such a stand is to follow the sun's arc across the sky, thus allowing the solar panels to remain perpendicular to the sun’s rays and soak up more energy, which results in generating more power than static, fixed-position panels.
Here are 5 pivotal steps to build your own Solar Stand/Sun Tracker:
Step 1: Design the Sun Tracker Frame
Draft a design for the frame that can support the weight of your solar panels. The design should enable the panels to tilt and rotate to track the sun's path. You can opt for a single-axis tracker that moves in an arc from east to west or a dual-axis tracker that also adjusts according to the season.
Step 2: Construct the Base and Vertical Axis
Build a sturdy base that can be anchored securely to the ground. Attach a vertical pole to the base that will act as the axis for the east-west rotation. Ensure the pole and base are strong enough to withstand wind and weather conditions without toppling over.
Step 3: Create the Tilt Mechanism
Attach a tilting frame to the vertical pole, allowing the panels to change their angle to follow the sun's seasonal height in the sky. Make sure the mechanism can be locked into place and easily adjusted as needed.
Step 4: Install the Rotation Mechanism
For the rotation mechanism, install a motor or a manual control that can turn your solar panels east to west. A motor will allow for automatic tracking, while a manual control will require periodic adjustments throughout the day.
Step 5: Set Up the Controller and Sensors
Integrate a solar tracking controller and sun sensors if you want automation in the tracking process. The sensors will detect the sun's position and signal the controller to adjust the solar panels accordingly.
Accessories and Tools Needed:
Accessories:
- Solar tracking controller
- Sun sensors (for automated systems)
- Motor with a gearbox (for automated systems)
- Bearings and mounts
- Adjustment locking mechanisms
Tools:
- Tape measure and ruler
- Level
- Saw (hand saw or power saw, depending on materials)
- Drill with a variety of drill bits
- Screwdrivers
- Wrench set
- Pliers
- Hammer
- Bolts, nuts, screws, and washers
- Metal or wood for the frame (weather-resistant)
- Concrete (for securing the base)
Additional Materials:
- Protective coatings such as paint or sealant for weatherproofing
- Wires and electrical fittings (as required for motor and controller integration)
When building your solar stand or sun tracker, always prioritize stability and durability to ensure your setup remains functional and safe throughout its operation. While manual tracking stands are simpler in design and require less technical expertise, an automated system can save time and effort in the long run.
