5. Solar Street Light Selection Guide

5.1 Select Pole Height by Scenario

Pole height selection directly affects lighting performance during solar street light installation:

Application Scenario	Road Width	Recommended Pole Height	Recommended Light Source Power
Village branch road	3-4m	5m	20-30W
Village main road	5-7m	6m	30-40W
Township road	7-10m	7m	40-60W
Municipal road	10-15m	8m	60-100W
Industrial park	Main road	8-10m	80-120W

5.2 Lithium Battery Configuration Calculation

Solar street light lithium battery configuration should be calculated based on the following parameters:

Basic formula: Battery Capacity (Ah) = Light Source Power (W) ÷ System Voltage (V) × Nightly Illumination Hours (h) × Rainy Day Backup Days ÷ Depth of Discharge (0.85)

Example: 40W LED light source, 12V system, 10 hours nightly operation, 3 rainy day backup needed: Battery Capacity = 40 ÷ 12 × 10 × 3 ÷ 0.85 ≈ 118Ah

In practice, if the system supports late-night power reduction energy-saving mode (e.g., reducing to 30% power for the last 4 hours), battery capacity requirements can be effectively reduced.

5.3 Solar Panel Configuration Principles

• Sunshine condition classification: According to China’s solar resource zoning, Category I regions (Tibet, Qinghai, etc.) have abundant sunshine with a ratio coefficient of 1.5:1; Category II regions (North China, Northwest) require a ratio of 2:1; Category III regions (South China, Southwest) with weaker sunshine require ratios of 2.5:1 to 3:1.
• Installation orientation: In the Northern Hemisphere, solar panels should face due south with a tilt angle equal to local latitude ±5°.

5.4 Solar Street Light Installation Precautions

1. Avoid shading: Installation locations should avoid obstructions from buildings, trees, etc., ensuring solar panels receive ≥6 hours of effective sunshine daily
2. Foundation construction: Pole foundation depth is generally 1/10 to 1/8 of pole height; for a 6m pole, foundation depth should be 0.6-0.8 meters
3. Spacing control: For equal-distance arrangements, pole spacing is 3-4 times the pole height; for staggered arrangements, spacing can be appropriately reduced
4. Waterproofing: All wire connections must be waterproofed; integrated storage-control unit protection rating should not be lower than IP65
