Step 3: Panel Power
I love these 4.5 volt panels. I use them for most all of my solar projects. They're small, light weight, strong, and throw out a lot of power.
Because my solar panels have little tabs on them I'm going to need to do some extra soldering and taping that you might not need to do with your solar panels.
That being said, no matter what kind of solar panel setup you're using, you'll want to be wiring them up the same way.
(For instance you could use a smaller panel to charge up a single AA battery, or a bunch of panels in a series to charge up a whole bunch of batteries at once.)

Is it okay if I want to hook my two 4.5v 80mAs in a series for just two batteries, to make it more powerful?

will two 4.5v solar cells be able to efficiently charger four AAs? Or is it best to stay with just 2 AAs for that?
