Experimental Evidence: Solar Street Lights with Wind-Solar Complementarity Exhibit “Pressure Resistance” Capability

With the continuous improvement of renewable energy research and development technology in our country, the application fields are flourishing. In addition to solar energy, another type of renewable energy that has gained much popularity is wind energy technology. Wind energy is a renewable resource that can be cyclically utilized, significantly reducing the pollution caused by coal-fired power generation. A common application is in outdoor lighting, such as wind-solar hybrid street lights.

China is vast and rich in resources, and each region has its own characteristics. The installation conditions for wind-solar hybrid street lights also vary according to local conditions. Next, let us briefly introduce some considerations regarding wind-solar hybrid street lights:

1. Wind-solar hybrid street lights are suitable for areas with abundant wind and sunlight resources

Wind-solar hybrid energy-saving street lights are best promoted in regions where both wind and sunlight resources are plentiful, such as the northwest and southeast regions of our country. In these regions, the use of wind-solar hybrid street lights is stable, as they can rely on small wind turbines for energy storage when solar energy is low but wind is strong; conversely, during sunny and breezy conditions, the photovoltaic system can primarily provide energy storage.

2. Wind-solar hybrid systems can start even at low wind speeds

The wind turbines of wind-solar hybrid energy-saving street lights are designed to be compact and sensitive to wind at low levels. They can start at a wind speed of 2.0 meters per second and can charge at 2.5 meters per second. Furthermore, in regions prone to typhoons, manufacturers can design wind-solar hybrid street lights to withstand wind forces of up to 14 grades and also contend with high salinity and humidity in coastal areas through appropriate anti-corrosion designs.

3. Smart control system of wind-solar hybrid street lights

The control system for wind-solar hybrid street lights is more complex than single energy source controls, as it must handle not only solar energy effects but also lighting schedules, overcharging protections for batteries, and under-voltage safeguards. In the case of overload or excessive electricity protection, this system can also take protective measures. The core capability of the control system is to maintain normal operation when the supplied voltage from wind and solar energy exceeds 15 volts but is less than 24 volts, boosting it to 24 volts.

4. Selection of batteries for wind-solar hybrid energy-saving street lights

The batteries used in wind-solar hybrid street lights are in a continuous cycle of charging and discharging. Therefore, most current solar wind-solar hybrid street lights employ maintenance-free gel batteries.
