Imported crystal silicon solar components and seales special PV gel battery free of maintenance are adopted, higher transformationrate of components, excellent anti-erosion. Intelligent Control System: Automatic electronic switch of light-control, time-control, without hook-up wire, personal control and management. It is widely used in illumination of highways, community roads and so on.
