Clarification about Solar Wind Turbine Street Light: Preferred Choice for Remote Area Lighting & Wind Power System

The vertical wind turbine is the heart of the wind component.
Unlike the traditional horizontal-axis wind turbine, a vertical design (e.g., Savonius or Darrieus type) captures wind from any direction, making it efficient in urban or mountainous environments where wind direction changes frequently.
The wind generator components include blades, rotor, stator, bearings, and generator core.
It starts generating power at wind speeds as low as 2.5–3 m/s, maintaining operation in moderate or turbulent conditions.

The hybrid operation ensures round-the-clock power generation:

Daytime: Solar Energy Dominates
Solar panels capture sunlight and convert it into DC electricity.
The controller directs the electricity to charge the battery.
Surplus power is stored for night use.

Nighttime or Cloudy Weather: Wind Energy Takes Over
When solar input decreases, the vertical wind generator begins supplying power.
The hybrid controller manages the balance, drawing from wind power or stored battery energy to operate the LED fixture.

   
Wind and solar are both available; the BOSUN high-quality controller blends both inputs perfectly.

This synergy between solar vs wind energy sources ensures continuous illumination regardless of weather or time of day.

Compared to grid-powered street lighting, a hybrid system can save 100% of electricity costs, as it’s entirely self-sustaining. In areas with 5 kWh/m²/day solar irradiance and average wind speeds of 4–6 m/s:

  
Each hybrid street light (with 300W solar + 400W wind) can produce 800–1,000 kWh/year, equivalent to saving around 0.5 tons of CO₂ emissions annually.
Over 10 years, a system of 100 lights can offset 5,000 tons of CO₂ and eliminate tens of thousands of dollars in grid energy costs.
