Introduction:
The Flat Single Axis Sunlight Tracking Bracket is a bracket structure used in photovoltaic systems. By rotating along a single horizontal axis, the photovoltaic modules can automatically adjust their angles as the sun's position changes, thereby improving light reception efficiency and power generation.
Advantages
Quantifiable Power Gain
Automatic east-west horizontal axis rotation minimizes the solar incident angle on the modules, resulting in an average annual power generation increase of 17% to 23%. This gain data is based on field comparisons of a sunlight tracking angle optimization algorithm and data from different latitudes.
High Tracking Accuracy
The system utilizes a DC motor with an encoder and a GPS time control module. Combined with dynamic correction based on light sensor data, the system maintains a real-time angle error within ±1.8°. Stable tracking is achieved through the controller's integrated time-position-light intensity three-dimensional matching logic.
Stable Structural Operation
The main shaft is machined from 45# quenched and tempered steel and precision-finished on a CNC lathe. Supported by dual-sided linear bearings, the bracket maintains torque balance throughout its 10-year design period and withstands wind pressures of 2400 Pa without the need for frequent adjustment or reinforcement.
Long Drive System Life
The drive system utilizes an integrated DC motor with gear reduction. The system is IP65 rated, with an average daily start-stop frequency of less than 45. The moving components have a theoretical lifespan exceeding 60,000 hours after mechanical fatigue testing.
