In India p-v cells or arrays are efficiently contributing in various sectors for power generation and lightning systems. Beside this it can also be used to make a system that operates on direct solar energy. Efforts are made to improve the efficiency of solar crop / potatoes dryer in the present work. The present model is consisting of photovoltaic cells, charge controller, battery, heating element or coil to improve the efficiency and specially modified for working in the night environment to dry crop, spices, potatoes, fruits and vegetables. In this dryer, the convection of heated air is forced due to difference in temperature. A domestic portable (mini) fan and heating element is used to improve the performance of solar power operated forced circulating dryer with the help of photovoltaic cell or solar panel. Existing solar dryer was modified by connecting solar collectors (1.955 m x 0.53 m). The dryer consist solar collector, battery, charge controller, frame, heating coil, fan, and cabinet. Frame was fabricated by L shaped angle iron having thickness 0.005 m. Cabinet consists of tin sheet and thickness of tin was 0.0011 m. The dimension of the cabinet was 0.95m x 0.56m x 0.39m (l x w x d). Modified dryer was found to be better over open sun drying in respect of moisture evaporation, as they required lesser time.
