solar panel wiring connections
How to connect 2 power supplies together? (solar panels)?
I’m just geting into electonics and stuff. So I am trying to make a simple USB charger. I’m looking for at least 4 volts output. What I’ve got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?
Each individual solar cell puts out .5 volts. You have to wire them in series(+ to – to + to – to + ). To get 4 volt you will need at least 8, 10 would be better, because they put out .5 volts max. with direct sunlight. The top side(shiny side) is the negative side, the back side is the positive side.
Before you hook them together, check each one by itself to make sure its good.
