OSI CO.,LTD.（H.K.）, the international service subsidiary of OS Group, is pleased to announce the introduction of solar street lights, a solar photovoltaics, easy-to-install outdoor lighting system for off-grid areas.
In the beginning, TerraSerde Solar Street Light is developed for off-grid area lighting in Nigeria.
The solar sheet module is made of amorphous silicon cells, which are harder to damage to bending and impact than a glass panel type photovoltaic module. The battery box and the LED light are certified IP44 and IP46 to be used outside.
TerraSerde is one of the best solutions for off-grid areas.
