When three capacitors are connected in a parallel the energy will be greater than that of series 
Explanation:
When a number of capacitors are connected in series, all of them will not be got the same voltage they will get different voltage
In series the total capacitance will be low while in parallel the total capacitance will be high
In parallel all capacitors will get the same voltage.
So, the conclusion is Capacitor will store more energy in parallel connection than the series connection
