40W Solar Street Light is a high-efficiency lighting solution typically used for main roads, campuses, and large parking areas. These systems generally use an "All-in-One" or "Semi-Integrated" design to house the solar panel, battery, and LED source.
Technical Specifications
The following technical details represent the standard configuration for a high-quality 40W system:
Luminous Efficacy: High-performance LEDs typically provide 140 to 170 lumens per watt, resulting in a total output of approximately 5,600 to 6,800 lumens.
Solar Panel (PV Module): Usually a 100Wp to 120Wp Monocrystalline or Polycrystalline panel. Monocrystalline is preferred for better efficiency in low-light conditions.
Battery Technology: Most modern systems use Lithium Iron Phosphate (LiFePO4) batteries (e.g., 12.8V 36Ah or 12.8V 30Ah). These offer over 2,000 charge cycles and better thermal stability than standard Lithium-ion.
Controller: An intelligent MPPT (Maximum Power Point Tracking) or PWM controller with dusk-to-dawn sensors and PIR motion sensors for energy saving (dimming when no motion is detected).
Physical Build: A durable Die-cast Aluminum housing with an IP65 or IP66 waterproof rating. It is typically designed for mounting on an 8-meter pole with a distance of 25 meters between units.
