5大核心参数
1. 太阳能电池板功率
电池板功率决定充电速度。以6米灯杆为例：
- 30W光源：配60-80W电池板
- 60W光源：配120-150W电池板
- 100W光源：配200-250W电池板
单晶硅效率高于多晶硅，推荐单晶硅电池板。
2. 锂电池容量
电池容量决定亮灯时长。计算公式：电池容量(Ah) = 光源功率(W) × 亮灯时间(h) ÷ 电池电压(V) ÷ 放电深度(0.8)
以30W光源、亮灯8小时为例：30×8÷12÷0.8=25Ah，建议选30Ah以上。
3. LED灯珠品牌
- 一线品牌：Lumileds、Samsung、Osram
- 二线品牌：晶电、三安、Epistar
优质灯珠光效≥150lm/W，寿命≥50000小时。
4. 防水等级
- IP65：防喷水，适合一般户外
- IP66：防大浪，适合暴雨地区
- IP67：短时浸水，适合低洼地区
5. 亮灯模式
- 光控+时控：天黑自动亮，定时关闭
- 光控+人体感应：人来自动全亮，无人半亮节能
- 微波雷达感应：比人体感应更灵敏，探测距离更远
避坑指南
- 虚标功率：标称100W实际只有30W，看光通量(lm)而非功率
- 电池虚标：标称100Ah实际50Ah，要求厂家提供放电测试报告
- 电池板以次充好：用B级或C级碎片电池板，效率低且衰减快
FAQ
Q：太阳能路灯阴雨天能亮几天？
A：标配设计支持3-5个阴雨天连续亮灯，可定制7天以上。
Q：6米太阳能路灯多少钱一套？
A：30W光源全套（灯杆+电池板+电池+灯头）约800-1500元，品牌差异较大。
5 Core Parameters
1. Solar Panel Power
Panel power determines charging speed. For a 6m pole:
- 30W light source: 60-80W panel
- 60W light source: 120-150W panel
- 100W light source: 200-250W panel
Monocrystalline silicon is more efficient than polycrystalline — recommended.
2. Lithium Battery Capacity
Battery capacity determines lighting duration. Formula: Capacity(Ah) = Light power(W) × Lighting time(h) ÷ Battery voltage(V) ÷ Discharge depth(0.8)
Example: 30W light, 8 hours: 30×8÷12÷0.8=25Ah, recommend 30Ah+.
3. LED Chip Brand
- Tier 1: Lumileds, Samsung, Osram
- Tier 2: Epistar, San'an, Epileds
Quality chips: efficacy ≥150lm/W, lifespan ≥50,000 hours.
4. Waterproof Rating
- IP65: Jet water proof, for general outdoor use
- IP66: Heavy wave proof, for storm-prone areas
- IP67: Brief submersion, for low-lying areas
5. Lighting Modes
- Photocell + timer: Auto on at dusk, timed off
- Photocell + PIR sensor: Full brightness when motion detected, dim otherwise
- Microwave radar: More sensitive than PIR, longer detection range
Pitfall Avoidance Guide
- Inflated wattage: Labeled 100W but actually 30W — check luminous flux (lm) not wattage
- Inflated battery: Labeled 100Ah but actually 50Ah — request discharge test report
- Substandard panels: B-grade or C-grade fragment cells — low efficiency and fast degradation
FAQ
Q: How many rainy days can solar street lights operate?
A: Standard design supports 3-5 consecutive rainy days; 7+ days available as custom option.
Q: How much does a 6m solar street light set cost?
A: 30W complete set (pole + panel + battery + light head) ~800-1,500 RMB, varies by brand.
