solar constant = 1.4kW/sq.meter = 1.4kjoule/sm2

or energy produced in 1sq.meter in 1 sec is 1.4 kjoules

so, energy produced in 5sq.meter in 1sec is 1.4  x 5 = 7.0kjoules

so in 2sec., energy produced in 5sq.meter  = 7.0 x 2 kjoules

                                                               = 14kjoules.
