Step 8: Solder The Charger

Picture of Solder The Charger

Now all you have to do is solder that bundle of positive, in my project red, wires to the positive point on the board. Then all the negative, in this project black, wires to the negative point on the board.

You're done with the circuit. You can test it now.

Usually I can charge a gadget just from sun. If it's not sunny the circuit should charge via batteries.

If I understand correctly, if I leave the batteries in and place it in the sun it will use BOTH the solar panel out and the batteries ate the same time if I want to charge anything, right? No need to take out the batteries? When the it's less sunny the batteries drain faster, when it's scorching the batteries drain slower?

Thanks for the instructions!

I'm not understanding. how do you know if its just charging from the panel and not the batteries? and when you say "test it" do you mean its going to run off the solar panel and not the batteries?
