Is it possible to combine parallel and Series

The Solar USB Charger can handle 2 A @ 20 V.

How would I connect two Series together to make a parallel circuit and increase just the amps

Once you have an assembly that produces the required voltage, you can replicate that assembly as many times as you'd like to get to the required amperage. For example, if your assembly produces 0.5 A @ 6 V, put two of those assemblies in parallel and you will have 1.0 A @ 6 V.

As the assemblies become higher powered, there are protection schemes you might want to consider, but this is the concept, anyway.

Just wondering if its at all possible to combine parallel and Series. So I have just the right amount of amp, and volt distribution

Im trying to make a great USB Solar Charger. And with connecting in series it just dont produce enough amp

Any thoughts or suggestions, or crasy Ideas would be helpful
