dear friend it is so simple i must tell you that energy of system is sum of self potential energy + interaction potential energy.
they are concentric . k 
so i m assuming Q’s radius is large.
KQ2/R + Kq2/r +KqQ/R

Bit correction in above answer self potential energy will be kq2/2r and kQ2/2R
Total Energy = kq2/2r + kkQ^2/2R + kQq/2R
 
Note :- by mistake wrote two k in 2nd part and its not removing
