Optimal Configuration and Price Analysis of 9-Meter Solar Street Lights Based on International Standards
Explore the ideal configuration, illumination spacing, and cost analysis of 9-meter solar street lights according to international lighting standards. Maximize performance with cost-effective solar solutions.
With the continuous advancement of smart solar lighting technology and the increasing adoption of energy-saving policies worldwide, 9-meter solar street lights are widely used in main roads, industrial parks, and large campus areas. This article analyzes an optimal lighting configuration plan that meets international road lighting standards while ensuring cost-effectiveness.
📌 Installation Scenario
- Pole height: 9 meters
- Road width: 9–10 meters (two-way single lane)
- Application scenario: Municipal roads, main roads, large community driveways
💡 Recommended Lighting Configuration
| Component | Specification |
|---|---|
| LED Light Head | 80W high-lumen LED (lumens ≥ 130lm/W) |
| Solar Panel | 180W monocrystalline silicon solar panel |
| Battery | 12.8V 80Ah lithium iron phosphate battery |
| Controller | Intelligent MPPT controller with dimming |
| Light Pole | 9-meter hot-dip galvanized pole with arm |
| Material | Anti-corrosion coating, Q235 steel |
📐 Illumination Simulation & Spacing Recommendation
According to international lighting standards (such as EN13201 or CIE115), for a 9-meter pole height and 80W LED:
- Recommended installation spacing: 30–35 meters
- Luminous uniformity (Uo): ≥ 0.4
- Average illumination: ≥ 20 lux
- Color temperature: 4000–5000K neutral white
Simulation tools like DIALux or Relux can validate this configuration with even lighting distribution and optimal visual comfort.
