Charging batteries is not easy. If you do something wrong, you could end up with a leaking battery or the battery could explode or catch fire.

Li-ion or Li-po batteries require advanced knowlegde, or a special chip.
NiMH batteries could be charged. There are examples for that.

So you could start with a few AA NiMH batteries.

I'm sorry, but I can't. I haven't build a solar powered charger yet.
To do it right, is not easy.

Need information about the Solar panel you want to use.
What voltage is it , and what is its power rating.
