The large-span flat single-axis tracking type flexible photovoltaic bracket system designed by the application has the characteristics of capability of automatically adjusting and tracking the incident angle of sunlight, short construction period, small number of pile foundations . The application belongs to the field of photovoltaic supports, and discloses a large-span flat single-axis tracking type flexible photovoltaic support system, which comprises a load-bearing cable system with a fishbone structure, wherein the load-bearing cable system comprises a first cable with a. A flat single axis tracking bracket is a mechanical structure designed to support photovoltaic (PV) modules and rotate them along a single axis—typically horizontal or tilted—to follow the sun's daily path from east to west. Unlike fixed-tilt systems, these brackets increase energy yield by 15–25%. A flat single-axis tracking bracket, comprising upright columns and a main beam rotatably supported on the upright columns, and further comprising a driving unit, a pin, and an insertion part. Drawing upon more than two decades of experience as a market leader in dual-axis tracking systems, KSI has harnessed its expertise to develop the most advanced, cost-effective, and. Single Axis Panel Independent Tracking System is driven by rotary motor, it can track the sunlight in real time and search for light intelligently. Comparing with thetraditional fixed bracket, the power generation can be increased by 10-15%. This system is suitable for multi scene large power. The ground tracking bracket is suitable for installation in large commercial, public utility power stations, mountainous and uneven areas. The product has a sturdy structure and strong stability. The main accessories are made of carbon steel and are hot-dip galvanized orgalvanized magnesium.
