This paper presents the evaluation of the performance of a constructed solar dryer using different floor types (black ceramic floor, white ceramic floor and the sandy floor). The solar dryer was used to perform experiment in which the effect of temperature, relative humidity and energy was observed. The result shows that higher efficiency was recorded with black ceramic floor compared to white ceramic floor and sandy floor. The hourly variation of temperature inside the dryers was much higher with black ceramic floor compared to white ceramic floor and sandy floor. The dryer showed higher energy with black ceramic floor compared to white ceramic floor and sandy floor. The relative humidity inside the dryer was relatively low with black floor compared to white and sandy floor.
