ABSTRACT : An indirect forced convection with photovoltaic powered forced circulation solar dryer has been built and tested. The main parts are: a V -grooved solar air collector, a scrap freeze as drying chamber, a battery and PV panel. The system is operated in one mode, sunshine hours. The dryer is used to dry 5 kg of ginger. Experiment were conducted on drying of ginger as drying of ginger is problem in north India and Mahatma Gandhi Institute for Rural Industrialization Wardha (MGIRI, A national institute under the ministry of MSME Government of India) asked to look into it and study the effect of drying as well the climatic and operational parameters on the dryer performance. The experiment was performed with and without reflective mirror at the Mahatma Gandhi Institute for the Rural Industrialization Wardha. The maximum collector outlet temperature was 66 0C and 81 0C without and with reflective mirror respectively. It was found that the average temperature inside the dryer without mirror was 63 0C which is below the maximum allowable temperature for ginger of
