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 solar panel

Monocrystalline is the most efficient type, with SunPower 24.1% conversion rates, and it is much higher than polycrystalline.

SMD LED Light source

LED Light Source

The cutting-edge technology of LED makes it more energy efficient and better able to convert battery power to illumination lighting.

Lumen depreciation chart of led comparing with multiple light

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.

LED lens

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 solar charge controller

MPPT Controller

MPPT controller (Maximum PowerPoint Tracking) is the most important component in a solar streetlight. It is 30% more efficient than a PWM controller.

motion sensor

Motion Sensor

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.

LiFePO4 battery

LiFePO4 Battery

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%
