2*26 photovoltaic array tracking solar bracket

A 2×26 photovoltaic(PV)array tracking solar bracketrefers to a mounting system designed to support52 solar panels(2 rows of 26 panels each)withsolar tracking capability,allowing the panels to follow the sun’s movement for increased energy production. Below are key details about this system:

1. System Overview

-Array Layout:2 rows×26 panels(total 52 panels).

-Tracking Type:Likely asingle-axis tracker(horizontal or tilted)ordual-axis tracker(more precise but costly).

-Panel Capacity:Depends on panel size(e.g. ,500W panels→~26 kW total system).

-Structure Material:Typically aluminum(lightweight,corrosion-resistant)or galvanized steel(stronger for windy areas).

2. Key Components

A.Tracking Mechanism

-Drive System:Motorized actuators or slewing drives adjust panel angles.

-Control System:Uses sensors(sun position,GPS,or algorithms)to optimize tilt.

-Power Supply:May integrate PV-powered motors or grid connection.

B.Mounting Structure

-Torque Tubes/Frames:Rotating beams that hold panels in place.

-Foundation:Ground screws,ballasted blocks,or concrete piers(depends on soil/wind conditions).

-Bearings&Pivots:Enable smooth rotation(critical for durability).

C.Panel Attachment

-Clamps:Rail-less or rail-based systems secure panels to the tracker.

-Wiring Management:Cable trays protect wires from movement-induced wear.

3. Advantages of Tracking vs.Fixed-Tilt

-Energy Gain:Single-axis tracking boosts output by15–25%,dual-axis by30–40%(vs.fixed).

-Land Efficiency:Higher energy per square meter.

-Adaptability:Better performance in low-light or diffuse sunlight conditions.

4. Design Considerations

-Wind Load:Tracking systems must withstand dynamic forces(IEC 61427 standards).

-Backtracking:Prevents row-to-row shading during early/late sun positions.

-Slope&Terrain:May require grading or custom foundations.

-Maintenance:Moving parts need lubrication and occasional servicing.

5. Installation Steps

1. Site Prep:Level ground,install foundations.

2. Assemble Tracker Structure:Torque tubes,supports,drives.

3. Mount Panels:Attach with clamps,connect wiring.

4. Calibrate Tracking:Test sensor alignment and rotation limits.
