| A solar dryer hybrid photovoltaic thermal (PV/T) system has been designed, built and its performance has been studied. This research aims to develop a stand-alone solar dyer system, portable and less maintenance. This system consists of three main parts; PV/T system with configuration-Z thermal absorber plate, multi-direction solar collector with cross absorber plate and drying chamber. The designed system is named multi-direction solar collector as the solar radiates through upper and around the sides. This situation may increase the amount of heat that will absorb by the absorber plate. Six sets of cross absorber plates were used in the multi-direction solar collector and they were assembled row by row. PV/T airflow uses configuration-Z absorber plate which is placed under the photovoltaic (PV) module. The amount of heat produced from the PV/T configuration-Z is used as the pre-heat before the hot air flows to the multi-direction solar collector, while electric energy from PV is used to operate the ventilation fan. The effectiveness of the solar dryer hybrid PV/T system was tested in the field under the daily solar radiation. The total efficiency generated from PV/T configuration-Z system is in the range of 35% to 52%. For the multi-direction solar collector system, the output range was generated between 32.0 C to 46.6 C, whereas the thermal efficiency is in the range of 50% to 70%. In conclusion, this system is an alternative of solar dryers where drying is simple, innovative and easy to maintain. 2023 Penerbit UTM Press. All rights reserved. |
