Wiring in series refers to connecting the plus of one panel or battery to the minus of another (+-). This adds the voltages of all panels together but leaves the current (amps) the same. For example, if you have four panels wired in series, each with 20 volts and five amps, the output would be 80 volts and five amps. Advantage.

The formulae to calculate the energy stored in capacitor can be given by E=1/2CV2 . So in our case for a 5.5V 1F capacitor when charged fully the energy stored will be. E = (1/2)* 1 * 5.52 E= 15 Joules. Now, using this value we can calculate how long the capacitor can power things, say for example if we need 500mA at 5V for 10 seconds.
