Optimal Solar Street Light Configuration for 6m Pole and 6m Wide Road — Cost-Effective & Standard-Compliant
Discover the optimal solar street light configuration for 6-meter poles and 6-meter-wide roads. Learn how to meet Chinese lighting standards with cost-effective lighting design, spacing, and simulation.
Meet China’s National Lighting Standards with High Efficiency and Cost-Effectiveness
1. National Standard Reference (CJJ 45-2015)
| Road Type | Avg Illuminance (Em) | Uniformity (Ehmin/Em) |
|---|---|---|
| Secondary road / residential street | 10–15 lux | ≥ 0.25 |
2. Recommended Solar Street Light Configuration
- LED Lamp: 30W–40W, ≥160 lm/W, 4000K, Ra≥70, Type II lens
- Solar Panel: 90W–100W monocrystalline, ≥21% efficiency
- Battery: LiFePO₄ 12.8V 24Ah, 5–8 years life, 3–5 rainy days backup
- Controller: MPPT with light + timer control
- Design: Integrated, IP65+, 120° × 60° light beam
- Pole: 6m hot-dip galvanized steel, 140–160mm base, wind resistance ≥ Grade 10
3. Installation & Spacing Suggestion
- Installation: Single-side layout
- Tilt Angle: 5°–15°
- Recommended Spacing: 20–25 meters (optimal: 22 meters)
Simulation achieves 12–15 lux average illuminance with 0.28–0.35 uniformity, sufficient for pedestrian and bicycle safety.
4. Cost Estimation (USD)
| Component | Estimated Price (USD) |
|---|---|
| 30W LED Light | $18 – $25 |
| 100W Solar Panel | $28 – $35 |
| 24Ah LiFePO₄ Battery | $32 – $40 |
| MPPT Controller | $8 – $12 |
| 6m Steel Pole + Foundation | $45 – $60 |
| Total (Per Set) | $130 – $170 |
Note: Pricing varies by quantity, certifications (e.g., CE, UL, BIS), and shipping terms.
5. Optimization Tips for Cost-Effectiveness
- Use multi-mode dimming to save energy at night (e.g., 50% after midnight).
- Choose certified, durable components for lower maintenance cost.
- Incorporate modular design for easier replacements and upgrades.
6. Frequently Asked Questions (FAQ)
- Q1: Can this setup handle several days of cloudy weather?
- A: Yes, with a 24Ah battery, it supports 3–5 days of backup power under dimmed lighting modes.
- Q2: How often should the battery be replaced?
- A: LiFePO₄ batteries typically last 5–8 years under normal usage.
- Q3: Do the solar panels require cleaning?
- A: Yes, we recommend cleaning every 3–6 months to maintain optimal efficiency, especially in dusty regions.
- Q4: Is the illumination sufficient for pedestrians and bikes?
- A: Absolutely. The average illuminance of 12–15 lux meets Chinese standards for residential and minor roads.
- Q5: Can motion sensors or IoT be added?
- A: Yes, PIR sensors, NB-IoT, or LoRa modules can be integrated for smart control and remote monitoring.
