This research aimed to apply solar energy for dry some medical plants. The solar dryer is manufactured at the research center for energy and environment of the ministry of industry and minerals. This study included two dealings, where three levels speeds were selected for the fan (0.045, 0.055, 0.068 m3/s) which represented the main factor and three kind of medical plants, (Basil, garlic and Cactus). The study was concerned on the efficiency of the drying room (%), the rate of drying (%),The daily theoretical proficiency of the solar collector (%),Cost accounting (ID/kg) and  the daily practical efficiency of the solar collector (%).Complete Randomized Design was followed to carry out this experiment with three replicates and  The Statistical Analysis System (SAS) (2012) was used to study the effect of the dried substance type ,air flow rate and their overlap with  studied parameters depending on the complete random design (CRD), differences were compared a many  the averages by less significant difference (LSD). The results showed that when the air flow rate increased, the daily theoretical efficiency would increase about 75.52 %, 59.50 %. The greater the theoretical and practical efficiency, the lower the intensity of the fallen solar radiation. The increase in the intensity of the fallen solar radiation leads to a reduction in the efficiency of the solar dryer . Increasing speed leads to lower temperatures, which in turn reduces the extraction of moisture from the plant and thus decreases the moisture mass of the vapors.
