The PV ventilated hybrid greenhouse dryer was designed and fabricated for drying of food grains. The greenhouse dryer with 446.7 X 213.4 cm size and with central height of 259 cm was constructed using 50.8X25.4 mm MS pipe, 19X30.2 mm MS angles. Clear twin wall polycarbonate sheet with 6 mm thick was used insulate the greenhouse dryer structure. Performance evaluation was conducted under no load test condition. It was observed that, the average temperature inside the dryer was 7.6-13.40C and 6.3-13.20C (22-43%) higher and average relative humidity was 26-47% and 23-40% lower than ambient temperature and relative humidity during May and December months respectively. Exhaust air flow rate varied in the range of 38.93-81.95 m3/min and 28-63 m3/min during May...
