Section 3: Farm Power

Sources of Power

Subtopic: Sources of power on the farm – human, animal, mechanical, electrical, wind, solar and biomass

Question Statement:

At maximum power output of a solar panel, voltage = 18 V, current = 5.56 A. Open-circuit voltage = 21.6 V, short-circuit current = 6.11 A. Find the fill factor. (Rounded to 2 decimal places)

Official Answer Key:

0.75 to 0.77

Step-by-Step Solution & Explanation

Fill Factor = (Vmp×Imp)/(Voc×Isc) = (18×5.56)/(21.6×6.11) = 100.08/131.976 ≈ 0.76.
