Solar lighting technology
Although the conventional solar streetlights have the separated structure of solar panel, battery and HID lamps, in recent years, the development of LED and battery technology has made it possible to design a compact solar street light, which could integrate LED, motion sensor, solar panel, and battery into one. And the modern-looking solar streetlights have several new technologies:
Monocrystalline solar panel
Monocrystalline is the most efficient type, with SunPower 24.1% conversion rates, and it is much higher than polycrystalline.
LED Light Source
The cutting-edge technology of LED makes it more energy efficient and better able to convert battery power to illumination lighting.
LM80 LED Lumen Maintenance
The LED light source, with pass LM80 test, has very low lumen depreciation within 30, 000 hours. This guarantees a qualified light source to have a 50, 000-hour lifespan.
Type II / III Light Lens
Type II / type III LED lens is required for road illumination, and is specially designed to get the batwing lighting distribution so that we can get the most use of the light
MPPT controller (Maximum PowerPoint Tracking) is the most important component in a solar streetlight. It is 30% more efficient than a PWM controller.
The integrated motion sensor can detect human movement, cooperating with controller components to adjust the LED brightness to 100% when somebody walks by, and to 25% when no movements are detected.
We have developed a new-generation Lithium LiFePO4 battery, which is composed of many small lithium batteries. It has more storage and capacity compared with Lead Acid batteries. better DoD up to 90%
