The aim of this research is to evaluate the performance of solar assisted heat pump dryer for chilli. The experiments were carried out on three types different of days such as clear day, intermittent cloud sky day and overcast sky day. The experimental results show that the useful heat gain of solar collectors for drying chili of the clear day, intermittent cloud sky day and overcast sky day are 14.5 kWh; 8.91 kWh and 0 kWh, respectively, and the corresponding energy consumptions of solar- assisted heat pump dryer are 19.2 kWh, 21.4 kWh and 26.1 kWh, respectively. The coefficients of performance (COP) in the three cases are 3.45, 3.46, and 3.51, respectively.
