PLEASE HELP 22 POWER SOURCES

I would REALLY like to hear more about these 22 variable power sources. 

I think you're on the right track with dc conversion.  What you do from there depends upon how you want to use the available output.  Perhaps you can connect these sources in such a way that results in a voltage and current levels suitable to apply to a charge controller.  The useful work, therefore, would be battery charging.   

Keep in mind these facts:

In a series circuit, the voltage will be the sum of each individual voltage, and the current will not be any greater than the current producing capacity of the lowest-current power source. 

In a parallel circuit, the current will be the sum of the current of each individual source, but the voltage will tend to be the same as that of the lowest-voltage power source.  (Voltage will rise and fall, depending on the size of the load).

You may want to create a series/parallel circuit in order to get the voltage and current characteristics you'll need.  It seems that you'll need more than the 22 sources you've listed if you want to power a charge controller.  Please provide more information about the power sources.
