How to connect electronic electricity system?

I have attached a drawing of all my components but have no idea about how to collect the system and how to code the Arduino.
Shortly the system should go from the solarcells where power is generated for the batteries. The solution should be that when you press the button, there is running electricity in the metal at the end for 1 min.
Hope someone can help. I am totally new to this.
Thanks!

That looks an awful lot like a test. How about you try to solve it post that result and then ask again?

What do you mean? The problem is that I don't know how to solve it.
