This is the latest all in one solar street light , which put the solar panel , led lamp , lithium battery and the controller in one kit , so when you got it just need to thighten the screws on the pole push the switch on ,everything  is okay, it will be on and off in the night and daytime automatically . Also as it used the lithium battery ,its lifetime is over 5 years , two times longer than the traditional one.so i could save a lot of maintenance cost in the future.

The main advantage :

1.put solar panel, LED lamp, battery and controller all in one box

2.without any cable, Integration design,

3.easy to install and ship and maintenance

4.using lithium battery with longer service lifetime......
