The wind solar hybrid street light system is a completely solar and wind-powered off-grid lighting system. It can address issues like limitless primary energy consumption, challenging transmission line installation, pollution of the environment, safety risks, and high electricity bills. This system has promising markets because it is a byproduct of clean and renewable energy. Read this passage, and you will find the three most important things about the system!
What is wind solar hybrid street light system?
In the hybrid street light system, wind wheels are used to collect wind energy. It rotates the wind turbine, which transforms wind energy into electrical energy. After the controller rectifies and stabilizes the voltage, it then transforms the alternating current into a direct one. The energy charges the battery and is then stored in it. In parallel, solar energy is directly converted into direct current, powering the load or being stored in the battery for later use.
The main components of the system include LED lights, the wind turbine, photovoltaic control systems, wind turbine control systems, batteries, and other parts. Additionally, it has brackets for solar cell modules, wind turbine accessories, light poles, embedded components, underground battery boxes, and other accessories.
What are the advantages and disadvantages of the wind solar hybrid street light system?
Advantages
- As the most prevalent natural energy sources, wind and solar energy are endless and renewable.
- In terms of timing and season, solar and wind energy are excellent complements for one another. During the day, there is sufficient sunlight and low wind, but at night, there is neither light nor strong wind. In the summer, there is high sunlight but low wind, while in the winter, there is weak sunlight and strong wind.
- Furthermore, inverters and batteries are universal components of photovoltaic and wind power generation systems.
- By configuring the system optimally based on the electricity load and the surrounding environment, the system helps decrease costs and guarantee reliability.
Disadvantages
- High failure rate
- Loud noise
- Low light brightness
Component selection and configuration
Wind turbines
When determining the wind turbine’s power, factors worth considering include the length of the period during which there is no effective wind speed, the lowest monthly average wind speed, the total annual electricity consumption, and the monthly average minimum electricity consumption. The lowest monthly average wind speed over the course of the year determines the wind turbine’s rated wind speed.
Light pole
To guarantee that the operation of the wind turbine is not impacted, the height of the light pole should be chosen in accordance with the environment. Typically, solar cell modules should avoid interfering with the wind turbine’s blades.
Battery
The battery pack’s series voltage needs to line up with the solar modules’ and wind turbine’s output voltages. The battery’s capacity is dictated by various factors, including the battery’s technical performance, the longest period without wind, the minimum daily power consumption, and the number of consecutive cloudy days.
Conclusions
The wind solar hybrid street light system combines wind and solar power, making up for the shortcomings of ordinary solar street light systems. With additional components like the wind turbine, the system can collect more energy, reduce electricity costs, and provide brighter light. But there is also a complaint about the unreliability of the system. No matter what, after thorough configuration of the components, the wind solar hybrid street light system can be a way to fulfill users’ illumination requirements.
