Solar energy is non-conventional energy obtained by changing solar thermal energy through certain equipments. Based on observation in 1 Ulu  Palembang, some people have produced crackers on a home industry scale with a total production capacity of 1000 kg in a single manufacture. Drying crackers is still done manually. The drying process is often constrained by weather factors. Thus, a dryer is designed using photovoltaic solar cell energy and thermal backup unit. To find out whether the dryer has been designed to work effectively and in accordance to its designs, it is necessary to conduct a study of the performance of the dryer in  form of technical calculations that take the problem to determine  the value of specific energy consumed, heat vaporation of H2O , and thermal efficiency of cracker drying process. From the calculation results, specific energy consumption consisted of 172; 121;113.8; 107.5;105.15;103.37; 97.11; 96.97; 98.68; 96.22 kJ/kg.  H2O evaporation heat 150.9563; 499.0338; 701.4600; 469.9254; 700.5107; 417.1445; 506.1046; 705.2896; 914.4727; 937.0139kj and thermal efficiency 32, 36, 40, 49, 53, 57, 69, 73, 78, 80 % of air velocity variations of  1- 10 m /s.
