A 12W Solar Street Light is a widely used off-grid outdoor luminary ideal for rural roads, residential streets, pathways, industrial premises, housing societies, and gardens.
Core Specifications & Parameters
| Component / Parameter | Typical Specifications |
|---|---|
| LED Wattage | 12 Watt |
| Luminous Output | ~1,400 to 1,600 Lumens (Efficacy: 120–140 lm/W) |
| Solar Panel (PV) | 40W – 50W Monocrystalline / Polycrystalline |
| Battery Type | 12.8V 12Ah – 24Ah LiFePO4 (Lithium Iron Phosphate) |
| Charge Controller | Microprocessor-based MPPT or PWM with Dusk-to-Dawn logic |
| Lighting Mode | Auto Dusk-to-Dawn (100% initial brightness, dimming to 40%–50% after 4–5 hrs) |
| IP Protection Rating | IP65 or IP66 (Weatherproof & Waterproof) |
| Recommended Mounting Height | 4 to 5 meters (13 to 16 feet) |
| Pole Distance Spacing | 10 to 12 meters apart |
Common Configurations & Architectures
* All-In-One (Integrated): The LED fixture, LiFePO4 battery pack, solar charge controller, and solar panel are integrated into a single compact housing. It offers easy installation with zero external wiring.
* Semi-Integrated: The LED housing includes the built-in battery and charge controller, while a separate 40W–50W solar panel mounts on top of the pole for flexible angle adjustment.
* Standalone (Traditional): Uses a separate external tubular/LiFePO4 battery box and panel structure mounted on a 5-meter GI pole.
Key Operational Features
* Dusk-to-Dawn Sensor: Automatically turns ON when ambient light drops below 4V–6V (nighttime) and turns OFF at sunrise.
* Motion / PIR Sensor (Optional): Operates at 100% brightness upon motion detection and dims down to 30%–40% power when idle to extend battery backup on cloudy days.
* Battery Protection System: Built-in protection against overcharging, deep discharge, reverse polarity, and short circuits.
