Solar hybrid street light Guide

Understanding Basic concept of Solar 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.

How to choose the right brightness of Solar hybrid street light

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:

Residential Streets: 5,000 to 12,000 lumens per light.
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

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 hybrid street light

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.

Installation Distance Guidelines for Street Lights

Road Width: 3-4m; Pole Height: 3-4m
Distance Between Poles: 10m
Road Width: 5-7m; Pole Height: 5-7m
Distance Between Poles: 10-25m
Road Width: 8-12m; Pole Height: 8-12m
Distance Between Poles: 30-40m
Main Traffic Arteries (20m wide); Pole Height: 12-14m
Distance Between Poles: At least 40m

What battery is best for Solar hybrid street lamp?

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.

How to choose All in one Solar hybrid street lamp pole?

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.

Long-Term Return on Investment: Although the initial investment is higher, in the long run, solar hybrid street lights provide a high return on investment through savings on energy costs and reduced maintenance expenses. The dynamic payback period typically ranges from 9 to 15 years, while the static payback period ranges from 6 to 8 years, depending on system configuration and usage environment.
Strong Adaptability: The system can be optimized based on local weather conditions and light intensity to ensure effective operation in various environments. For instance, polycrystalline solar panels can be used in regions with good sunlight, while monocrystalline solar panels may be utilized in areas with poor sunlight.
Social Benefits: The installation of solar hybrid street lights signifies technological advancement and an increased awareness of environmental protection, contributing to an improved urban image. In rural areas, the use of solar hybrid street lights can save conventional energy consumption, reduce environmental pollution, and promote the construction of a new socialist countryside.
