The Solar Power Module provides power for eChucK circuits.  You simply plug this module into the power bus strip on either side of the breadboard and you've got a 3V, 25mA power supply provided by the wrap-around solar cell.  Decoupling capacitors are built-in so you don't need to worry about those either.  

If you would like to use a larger voltage you can connect them in series, typically one on each side with a wire connecting the Ground of one to the VDD of the other.  Then you have a 6V center tapped supply.  Use the center tap as an artificial ground for any analog circuits you may have.  If you need more current, just put two or more Solar Power Modules in parallel, running down the bus strip.  

The mounting holes provided permit you to incorporate Solar Power into a clear plastic enclosure such as the Sparkfun project case (part Number WIG-08632).  This case is appropriate for smaller projects as you can mount eChucK modules to both the top and the bottom of the case and run wires between them.  Remember, of course, to leave extra length between the two sides of the case so that you can open it up easily for service.  Sparkfun is located on the web at www.sparkfun.com.
