Optimal Configuration and Illumination Simulation for 7-Meter Solar Street Lights Based on International Standards
Explore the ideal configuration for 7-meter solar street lights following international lighting standards like IESNA RP-8-18 and CIE 115, including LED wattage, panel sizing, battery capacity, spacing, and photometric simulation.
1. Introduction
With growing demand for sustainable lighting, 7-meter solar street lights are widely used in urban streets, residential zones, industrial areas, and parks. To ensure compliance with global standards, proper configuration and spacing are essential.
2. Reference Standards
This guide follows:
- IESNA RP-8-18 (North America)
- CIE 115:2010 (Europe/International)
For residential/collector roads:
| Lighting Class | Average Illuminance (lux) | Uniformity (Emin/Em) |
|---|---|---|
| Class S3 | 10–15 lux | > 0.25 |
3. Recommended Configuration for 7-Meter Pole
| Component | Specification |
|---|---|
| LED Lamp | 40–60W, 4000K, >160 lm/W, Type II or Type III optics |
| Solar Panel | 150–180W Mono-crystalline, 21% efficiency |
| Battery | LiFePO4 12.8V 40–50Ah, lifespan 5–8 years |
| Controller | MPPT, auto dusk-to-dawn with dimming |
| Pole Height | 7 meters, hot-dip galvanized, ≥ Wind Zone IV |
| Installation Angle | 15° tilt, single or staggered layout |
4. Illumination Simulation
Using 45W LED at 7m height, 28m spacing, single side installation on a 7m-wide road:
- Average Illuminance: 14–16 lux
- Uniformity: 0.30–0.40
- Energy Optimization: 30% dimming after midnight
5. Spacing Suggestions
| Road Width | Recommended Spacing | Layout |
|---|---|---|
| 6–7m | 25–30m | Single side or staggered |
6. Estimated Cost (USD per set)
| Component | Cost (USD) |
|---|---|
| LED Lamp (40–60W) | $25–$35 |
| Solar Panel (150–180W) | $45–$60 |
| Battery (40–50Ah LiFePO₄) | $60–$80 |
| MPPT Controller | $12–$18 |
| 7m Galvanized Pole | $70–$90 |
| Total | $212–$283 |
7. FAQ
Q1: Is this configuration compliant with European lighting norms?
Yes. It meets Class S3 per CIE 115 and typical RP-8-18 residential road requirements.
Q2: Can the system work during continuous rainy days?
With 3–5 days of battery autonomy, it ensures reliability even in cloudy conditions.
Q3: How often should the battery be replaced?
LiFePO₄ batteries typically last 5–8 years with minimal maintenance.
Q4: What if higher illumination is needed?
Upgrade to 60W LED and reduce pole spacing to 22–24 meters.
Q5: Can smart controls be added?
Yes. You can integrate Zigbee/LoraWAN-based IoT controllers with dimming, monitoring, and remote scheduling.
