Battery-less solar generator
Looking through the comments regarding that capacitor it doesn't seem to be a 2 F capacitor.

If it were a 2 F capacitor the amount of energy stored would be something like 144 Joule. This would mean it could (theoretically) supply 144 Watt for 1 second. Good enough for you? 

The information about the buck regulators says a lot of things, no telling of which is true. 


200 max output, but only 8 A current. Which at 12 V would be 12 x 8 = 96 W
4 A current output without heat sink (48 W @12 V).


Possible faults that may occur:


Overheated components
Lower power output than expected
Unpredictable behaviour by power limited by cells, contact resistance, capacitor discharge
Soldered joints will break, you mentioned using this for camping. Unfastened         wires connected to soldered joints will break...


I think you would be better off with placing a lead acid battery in this circuit instead of a capacitor.
