  • Wind Turbines: They generate electricity from wind energy, especially during nighttime or on cloudy days when solar energy is insufficient, providing supplementary power.

System Components:

  • Solar Panels: Typically installed at the top of the light pole or integrated into the pole structure to convert solar energy into electrical power.
  • Wind Turbines: Usually mounted at the top of the pole or nearby, they harness wind energy to generate electricity.
  • Battery Storage: Rechargeable batteries store energy collected from solar and wind sources for use at night or during rainy periods.
  • Controller: Manages the charging and discharging process of the solar panels and wind turbines, switching power sources as needed to ensure stable system operation.
  • Light Fixture: Generally employs LED technology due to its efficiency and longevity.

Smart Management:

  • Real-time Monitoring and Control: The system uses a controller to monitor parameters like the voltage of the batteries, environmental brightness, and temperature, allowing for precise lighting control.
  • Automatic Switching Function: The controller can automatically select the most suitable power source based on real-time energy supply conditions, ensuring continuous and stable lighting.

Solar wind hybrid street lights​ Guide

Understanding Basic concept of Solar wind hybrid street lamp

To choose solar street lights, it is essential to understand several key concepts. The first is lumens and watts, the second is lux, the third is color temperature.  Lumens represent the output brightness. Lux signifies the actual brightness of illumination. Color temperature refers to the color of light emitted by a light source.

Lumen Requirements for Outdoor Street Lights

The lumen output needed for outdoor street lights varies based on factors such as pole height, road width, and ambient light conditions. It’s essential to consider recommended illumination levels for different road types:

  1. Residential Streets: 5,000 to 12,000 lumens per light.
  2. Main Roads and Highways: Typically require 10,000 to 15,000 lumens for adequate safety.

Lumen Output by Pole Height:

  • 6 m Height: 6,000 lumens
  • 8 m Height: 8,000 lumens
  • 10 m Height: 10,000 lumens
  • 12 m Height: 12,000 lumens
  • 14 m Height: 15,000 lumens
  • 16 m Height: 18,000 lumens
  • 20 m Height: 25,000 lumens

Selecting the appropriate lumens and watts can significantly enhance both lighting quality and energy efficiency. For detailed guidance and examples, please refer to the link: Lumens vs watts: lumens to watts conversion chart

Lux signifies the actual brightness of illumination, measuring light flux per unit area, and is commonly used to assess lighting effectiveness and suitability.

Highways:

  • First-class and Second-class: 20 lx (low) / 30 lx (high), uniformity: 0.4.
  • Third-class: 15 lx (low) / 20 lx (high), uniformity: 0.4.
  • Fourth-class: 10 lx (low) / 15 lx (high), uniformity: 0.3.

Values apply to asphalt; concrete requirements can be reduced by up to 30%.

Urban Roads:

  • Expressways and Main Roads: 20 lx (low) / 30 lx (high), uniformity: 0.4.
  • Secondary Roads: 15 lx (low) / 20 lx (high), uniformity: 0.4.
  • Side Roads: 10 lx (low) / 15 lx (high), uniformity: 0.3.

Rural Roads:

  • Primary Roads: 10 lx (low) / 15 lx (high), uniformity: 0.3.
  • Side Streets and Lanes: 5 lx (low) / 8 lx (high).
  • Public Activity Squares: 10 lx (low) / 15 lx (high).

Choosing the right color temperature for solar street lights is crucial for achieving the desired ambiance and visibility. Color temperature is measured in Kelvin (K) and affects how light appears; warmer temperatures (below 3000K) emit a yellowish light, creating a cozy atmosphere, while cooler temperatures (above 5000K) produce a bluish-white light that enhances visibility and safety.

When selecting the color temperature for solar street lights, the following standards are worth considering:

Road lighting color temperature suggestions:
Highway lighting: not more than 5000K, usually choose low and medium color temperature, but in some projects can be used 5700K or higher.

Airport road lighting: no more than 4000K, glare control lens should be added.

Residential road lighting: Low to medium color temperature is recommended, usually kept below 4000K.

Rain and fog road lighting: it is recommended to use low color temperature lamps, the recommended range is 2700K-3500K.

Road lighting in commercial areas: High color rendering index (CRI), low to medium color temperature light sources are recommended.

Parking lot lighting: 5700K-6500K color temperature is recommended.

Garden and industrial lighting: Warm color temperature 2700K-3000K is recommended to create a warm and relaxing atmosphere.

How to choose Solar wind hybrid street light

After understanding the basic parameters of solar street lights, we can determine the appropriate height and spacing to determine the required quantity according to the project application scenario and the required standards of the project, and then choose the appropriate brightness of solar street lights, pole height, battery type, etc.

Installation Distance Guidelines for Street Lights

  1. Road Width: 3-4m; Pole Height: 3-4m
    Distance Between Poles: 10m

  2. Road Width: 5-7m; Pole Height: 5-7m
    Distance Between Poles: 10-25m

  3. Road Width: 8-12m; Pole Height: 8-12m
    Distance Between Poles: 30-40m

  4. Main Traffic Arteries (20m wide); Pole Height: 12-14m
    Distance Between Poles: At least 40m

Lithium iron phosphate battery (LiFePO4): Despite the higher price, it provides higher energy density, longer service life (usually up to 8-10 years) and better stability, suitable for solar street lights.
NiMH battery (NiMH): environmental protection is better, but more maintenance, suitable for high energy consumption equipment, not suitable for low power recycling of solar lamps.
Nickel-cadmium batteries (NiCd): Despite their low price, they are not recommended for solar street lights because of the “memory effect” and toxicity problems.
Lead-acid batteries: although low cost and stable voltage, but large volume, short service life, frequent maintenance.
Gel cells: A modified version of lead-acid batteries that performs better but may be more expensive and suitable for extreme climatic conditions.

Material Requirements:

  • The material of solar light poles directly impacts their lifespan.
  • Commonly used materials like Q230 steel are susceptible to corrosion, so they are often galvanized for enhanced corrosion resistance.
  • Hot-dip galvanized poles offer better corrosion protection compared to cold-dip galvanized ones.
  • Some poles are made of stainless steel or undergo anodizing for superior corrosion resistance, albeit at a higher cost.

Wall Thickness Requirements:

  • Besides material, wall thickness is crucial for wind resistance and load-bearing capacity.
  • Wall thickness should be determined based on the specific installation scenario to ensure the pole’s longevity.
  • Recommended wall thickness varies based on pole height:
    • 2-4m poles: Minimum 2.5cm
    • 4-9m poles: Minimum 4-4.5cm
    • 8-15m poles: Minimum 6cm
  • Areas prone to strong winds may require thicker wall thickness for added durability.

Considering these details, users can select solar light poles with suitable materials and wall thickness to ensure longevity and reliability based on their budget and installation requirements.
