The Schematic on Google Docs:

If you want to make this project, keep in mind that I had some mistakes during making this project:

1. i forgot the resistors for LEDs, you should use resistors for LEDs to save your battery charges for long time.
2. Those solar boards are each 1.4V with 350mA current rate which are not powerful enough to push the charges into batteries, you should use 3 or 4 of them.
In the next project I explain this more with correct practical examples.
