Renewable energy sources such as solar energy for drying purposes in a more effective and efficient way is inevitable for preservation of agricultural products in developing nations with inadequate access to electricity. This study investigates the effects of using a solar tracking device on the energy performance of drying processes. Three categories of drying conditions were carried out simultaneously; for a fixed solar box dryer, a solar box dryer aided by a tracking device, and open air drying over an effective total drying time of 6 hours each day, for 5 days.
