Power from solar photovoltaic system was used for operation of a grader for grading of fruits and vegetables. A solar panel of 400 W (4 solar modules of 100 W each with open circuit voltage 18 V) was used to operate the system. The direct current (DC) power of the solar panel was used to run the 150 W DC motor of the grader. The grader was tested for grading of potatoes in three sizes. The output capacity of the grader was found as 600 kg/h. A 12 V/7 Ah battery may also be used to operate the grader in the absence of solar energy.
