Well, goes like this, I want to set something up along the lines of a solar pannel that charges a cap with enough power to work 9 6000mcd blue leds when needed, but will cut power from the panel -> cap when it gets full

To be honest I don't really know where to start, I know I'm going to have to pick up a solar pannel, the leds, a blocking diode, ect

Any help would be great

I would suggest using some cheap rechargeable batteries instead of a cap to start with. To do the rest, I would say use a transistor (or mosfet) to control the connection from the solar panel to the energy storage device. From there you can feed the voltage from the storage device to the gate of the transistor (or mosfet) to turn it on or off.
