Why do solar trackers need wind tunnel tests?
Wind tunnel tests are hence needed to examine the aerodynamic stability of the tracker array under different influencing factors, such as incoming flow conditions, tracking angles, and layouts. These findings will then help solar tracker manufacturers to determine the parameters in the design of the solar tracker structure.
How stable is a solar tracker?
The aerodynamic stability of a solar tracker is mainly determined by damping, stiffness (frequency), and tilt angle of modules; DAF reflects the dynamic amplification effect of the wind load, but not its structural stability. When the tilt angle is large, solar trackers have relatively good stability.
Does wind affect solar trackers?
The industry-wide adoption of large-format modules means that solar systems have become bigger than ever, resulting in higher flexibility of the tracker structure and increased susceptibility to wind-induced damage. Yet, building codes do not consider the aeroelastic effects of winds on solar trackers.
How does a tracking photovoltaic array affect wind speed?
The presence of the tracking photovoltaic array significantly blocks and reduces the wind speed within the array. At a tilt angle of β = 45°, the wind speed reduction at the measuring points affected by the array reaches 23–––32 %. This blocking effect stabilizes as the number of photovoltaic array rows increases.
Does a tracking photovoltaic system block incoming wind?
Conclusion This study thoroughly investigates the near-ground incoming wind characteristics of the tracking photovoltaic system, spatial coherence, and the photovoltaic array's impact on the flow field, particularly its wind blocking effect.
What is a wind tunnel test?
Wind tunnel tests mainly include the rigid pressure test and the full aeroelastic test. The rigid pressure test determines the system coefficient, torque factor, and Dynamic Amplification Factor (DAF). Meanwhile, the full aeroelastic test determines the critical wind speed, which occurs when damping is negative.
