Are there specific requirements for the installation site of solar streetlights that combine wind and solar energy?

Solar Street Lights

The selection of wind turbine sites is a very complex issue. The installation of large wind turbines often requires years of meteorological data, several years of practical measurements, and consideration of various other factors to determine the installation site.

For the installation of small wind turbines focusing on solar and wind hybrid systems, it is common to select a site where residential buildings already exist. Under these conditions, several key points should be noted when choosing the installation site for small wind turbines:

1. Determine the predominant local wind direction. Wind turbines should be installed upwind of this direction. For example, in most areas of Inner Mongolia, the prevailing wind is from the northwest, so wind turbines should be installed in the northwest direction of the building to reduce the obstruction effect on the wind. It is also required that there are no other buildings or obstacles such as trees upwind of the solar street light wind turbine.

2. Try to avoid the effects of turbulent wind. Turbulence is caused by wind flowing over rough surfaces or obstacles, leading to sudden changes in wind speed and direction. Turbulence can reduce the power output of the wind turbine, cause vibration, noise, and affect the lifespan of the turbine. To avoid turbulent wind effects, solar street light wind turbines should be installed in relatively open and unobstructed areas, away from buildings to a safe distance.

The wind speed vertical shear within the range of the rotor height of the solar street light wind turbine should be minimal. Vertical shear refers to the difference in wind speed at various height levels caused by topography and ground roughness. This vertical shear places uneven forces on the rotor blades, which can lead to rotor damage. To avoid the impact of vertical shear on the rotor, the appropriate installation height of the solar street light wind turbine should be selected. In areas with many nearby obstacles, if the solar street light wind turbine is to be installed close to a building, the height of the turbine should be increased.
