1. Using the microcomputer intellective controller to
transfer the light energy to electrical energy. East to
install since no wiring & trenching, energy conservation and
environmental. 

2. The microcomputer intellective controller is composed by
advanced special-purpose integrated circuit, high
conversion efficiency, prevent over-load & over discharge. 
Output short circuit protection, extend work life, on the
safe side, convenient usage. 

3. High effective Non-maintaining accumulator cell, strong
storage, durable usage. 

4. Automatic track type time controller. Automatically
adjust the working time along with different illumination
time in various seasons. For extending the work time energy
conservation intellective controller will automatic
shut-off the light at the deep-night.
