Abstract: To dry a variety of agricultural goods, an indirect, active-type, affordable hybrid solar dryer was created. This dryer functions solar energy through solar panels and without solar panels through sun rays. The dryer was constructed using inexpensive, locally accessible materials. The dryer is made up of a solar panel, a thermostat, a drying chamber, and a fan with a regulator to create the necessary air flow in the system for the stated item that has to be dried or dehydrated. Because of their enormous output and significant loss in India, grapes were chosen as the experimental fruit. Additionally, raisins, which have significant nutritional content and are a staple food, are dried grapes. We have achieved in determining drying efficiency of grapes ,bananas etc food items, drying rate and quality of drying. drying time & temperature for the grapes and other food itmes available around Pune. We have made sustainable solar dryer with ambient heat under humidity. The dryer efficiency at the end of 8 h of drying is 5.05 and 6.96 % for 1  m/s, with reducing moisture content form 80% to 15 % with max range of temperature of 54-64 degree Celsius .
