Answer:
   Ben's
Step-by-step explanation:
If E is the amount of energy that each full set of panels produces, then ...
   3 of Ismael's 5 panels produce 3/5E
   4 of Ben's 6 panels produce 4/6E
We can compare these fractions when they have a common denominator.
   3/5E = 18/30E . . . . energy from Ismael's panels
   4/6E = 20/30E . . .  energy from Ben's panels
   18/30 < 20/30 . . . . so Ben's panels are producing more energy
