Compact Design: All components—including solar panels, batteries, controllers, and lamps—are mounted on a single pole, creating a cohesive unit. This compact design enhances integration and saves space.
Easy Installation: With all components pre-integrated, installation is straightforward—requiring only the fastening of the pole base. This greatly simplifies the installation process, which often does not involve on-site assembly, thus reducing construction time and costs.
Convenient Maintenance: The integrated design makes post-installation maintenance simpler. All components are concentrated in one location, facilitating inspections and repairs.
Flexible Adjustment: A movable clasp under the solar panel allows for vertical adjustments of 10° to 60° and 360° rotation horizontally. This flexibility enables optimal positioning for sunlight capture, enhancing solar energy utilization.
Smart Control: Equipped with an advanced smart control unit, these lights can automatically adjust brightness and utilize sensors for automated on/off control. For instance, the lights will automatically illuminate when pedestrians or vehicles approach, and turn off when the area is clear, promoting energy conservation.
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:
Lumen Output by Pole Height:
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:
Values apply to asphalt; concrete requirements can be reduced by up to 30%.
Urban Roads:
Rural Roads:

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.

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
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

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:
Wall Thickness Requirements:
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.

Adaptive Brightness Control: The intelligent control unit can automatically adjust streetlight brightness based on ambient light levels, achieving energy savings of 60% to 80% compared to traditional streetlights.
Automatic On/Off Control: Sensors manage the lighting, preventing unnecessary energy wastage—lights turn off when no activity is detected and illuminate when motion is sensed.
Centralized Installation: With all components located at the top of the pole, the risk of theft is minimized. In contrast, traditional solar lights often have batteries and other components at ground level, making them vulnerable to theft.
High-Quality Components: Utilizing high-energy, long-lasting gel batteries, these lights can last up to 8 years. Gel batteries offer superior weather resistance and stability across various environments.
Intelligent Protection Mechanisms: Controllers include safeguards such as temperature compensation, overcurrent, undervoltage, overvoltage, and short-circuit protection, significantly prolonging battery life. For example, temperature compensation ensures optimal battery performance in extreme conditions.
Innovative Light Distribution Design: The fixtures feature a new light distribution design that provides the vertical illuminance required for pedestrians, offering a wider dispersal of light and improved uniformity on the roadway. For example, on rural main roads roughly 5 meters wide with high foot traffic, lights installed 5 meters high at a 30° angle can achieve an average illuminance of no less than 3 lx within a 5-meter radius.
Cost Control: The integrated design allows for more manageable system costs, providing a better cost-performance ratio compared to traditional solar lights. The lower installation and maintenance costs translate into greater economic benefits over the long term.
Lightweight Structure: The elegant and straightforward design complements modern urban landscapes, ensuring the integrated components appear coordinated rather than bulky, thereby enhancing overall visual appeal.
