15W Solar Street Lights Installation in Uttarakhand & Himachal Pradesh.
A 15W Solar Street Light paired with a 12.8V 15Ah LiFePO4 battery is a highly efficient setup for residential streets, pathways, and garden lighting. The use of a 12.8V system (nominal voltage for Lithium Iron Phosphate) is superior to standard 3.7V or 11.1V systems because it offers better thermal stability and a longer life cycle.
Core Specifications
| Feature | Details |
| LED Wattage | 15W (Typically producing 1,800 – 2,250 Lumens) |
| Battery Type | LiFePO4 (Lithium Iron Phosphate) |
| Battery Capacity | 12.8V 15Ah (Total Energy: 192Wh) |
| Solar Panel | Recommended 30W 40W (Mono or Polycrystalline) |
| Charging Time | 6 – 8 hours of bright sunlight |
Performance Breakdown
* Efficiency: The 12.8V architecture reduces current flow for the same power compared to lower voltage systems, which minimizes heat loss in the wiring and controller.
* Lifespan: LiFePO4 batteries are rated for 2,000 to 3,000 cycles, meaning the battery should last 5–8 years before needing replacement.
* Smart Controls: Most models include a PIR Motion Sensor. The light typically stays at 30% brightness and ramps up to 100% only when motion is detected, significantly extending the 15Ah battery's runtime.
Installation Guidelines
* Recommended Mounting Height: 4 to 5 meters 5m & 6m
* Recommended Spacing: 10 to 12 meters between poles for uniform light distribution.
* Inbuilt Protections: Ensure the unit has an integrated BMS Battery Management System for overcharge, deep discharge, and short-circuit protection. Note: For optimal performance, ensure the solar panel is tilted toward the south (in the northern hemisphere) and kept clear of shadows from trees or buildings
