Step 4Wiring up the circuit
This shows the circuit I have soldered. I have made it bigger for easier understanding. It can actually be made much much smaller (half the size or even smaller).

You're done! Now you can break away from power points and even have Arduino projects out in natural environments without a problem.

would a 12v 200mA solar panel be enough?

Nice Project.
But one question, how big should the Solar-Panel be to charge the battery ?
Can it also be to big and overcharge?

It really depends on the voltage of your battery. Different solar cells have different ampere rating and voltage, so you would not something that is too powerful or too weak in comparison to your battery.
