12W solar street light system is designed for high-efficiency outdoor lighting, typically used for pathways, residential colonies, and rural streets. These systems are commonly available in All-in-One (integrated), Semi-Integrated, or Standalone configurations.
Technical Specifications
Most 12W units adhere to standard MNRE (Ministry of New and Renewable Energy) or industry-standard specifications:
LED Luminaire: A 12W LED chip (often brands like Osram or Bridgelux) providing roughly 1,500 to 1,600 lumens. They generally have a color temperature of 5500K - 6500K (Cool White).
Solar PV Module: Usually a 40Wp to 75Wp Polycrystalline or Monocrystalline panel to ensure full charging within 6–8 hours of sunlight.
Battery: Typically a 12.8V 12Ah to 30Ah Lithium Ferro Phosphate (LiFePO4) battery, known for a longer cycle life (up to 2,000 cycles) compared to Lead-Acid.
Controller: Inbuilt PWM or MPPT charge controller featuring Dusk-to-Dawn sensors (automatic switching) and often motion sensors that dim the light to 30% brightness when no movement is detected.
Casing: IP65 or IP66 rated Aluminium Die-Cast body for weather and rust protection.
