An air-heating flat plate solar collector having a photovoltaic panel as its absorber was constructed and tested. The collector was of a ″flow under the absorber with no cover plate″ type. The amorphous type photovoltaic panel was used to convert solar radiation into electric power to charge a battery. Two blowers were powered by the battery to draw ambient air through a channel underneath the panel. The collector was designed to supply the air, heated by the sun when it is available, for low temperature drying of agricultural products without relying on any external power source. The average daily thermal and electrical efficiencies were found to be 18. 7% and 2. 5%, respectively.
