Product Introduction
Technical Specification Comparison: 15W vs. 20W All-in-One Solar Street Lights
For B2B procurement managers and municipal engineers, selecting the correct wattage involves balancing light coverage with battery autonomy. As a pioneer with 20 years of export experience, Decano provides this technical breakdown to help you determine the optimal configuration for your project site.
1. Core Parameter Comparison Table
| Technical Metric | Decano 15W Series | Decano 20W Series |
|---|---|---|
| Luminous Flux (Lumens) | 1,800 - 2,100 lm | 2,600 - 3,200 lm |
| Ideal Mounting Height | 3.0 - 4.0 Meters | 4.0 - 5.5 Meters |
| Solar Panel (Monocrystalline) | 30W - 40W | 50W - 60W |
| LiFePO4 Battery Capacity | 12.8V 15Ah - 18Ah | 12.8V 24Ah - 30Ah |
| Illumination Width (Road) | Up to 4 Meters | Up to 6 Meters |
| Recommended Pole Spacing | 10 - 13 Meters | 15 - 18 Meters |
2. Strategic Application Scenarios
- The 15W Integrated Light (The Pedestrian Choice): Optimized for garden paths, cycling trails, and secondary residential walkways. At a 3.5m mounting height, it provides high visual comfort without light pollution. It is the most cost-effective choice for B2B projects where the road width is under 4 meters.
- The 20W Integrated Light (The Residential Standard): Designed for minor urban roads, parking lots, and commercial perimeters. The 20W model produces over 3,000 lumens, which is the threshold required for High-Definition CCTV Facial Recognition at night. Due to its higher mounting height, you can use fewer poles to cover the same road distance, reducing the Total Project Budget.
3. Why Decano Components Define Reliability
Because the 20W model consumes more power, the "system balance" is critical for 365-day operation.
- Upgraded MPPT Tracking: Our 20W series features a higher-amperage MPPT Controller to ensure the larger 60W panel can fully recharge the high-capacity battery in just 6 hours of sunlight.
- Professional Road Optics: We use Asymmetric Type II/III Lenses for both. However, the 20W lens is engineered with a wider "beam throw" to maximize the spacing between poles, further increasing the project's ROI.
- Thermal Control: Our 20W units utilize an oversized die-cast aluminum heat sink. This is vital to prevent the LED chips from overheating and the LiFePO4 battery from swelling in high-ambient-temperature regions.
