The effect of various operational conditions on the outlet temperature and efficiency of a solar air colllector is investigated. A parametric study including operational parameters of collector inlet temperature, mass flow rate of air, solar irradiation and ambient temperature is performed to predict the outlet temperature of the air and efficiency of the collector. The parametric study is simulated for a v-groove type solar air collector. Results show that the increase in the collector inlet temperature, solar irradiation and ambient temperature have possitive effects on the collector outlet temperature whereas the mass flow rate of air has a negative effect. Regarding the collector efficiency, the mass flow rate of air and ambient temperature have a possitive effect whereas the collector inlet temperature has a negative effect. Furthermore, the collector effciency increases rapidly with increasing solar irradiation till a certain value of solar irradiation (about 300 W/m2). After this value, the effect of the solar irradiation on the collector efficiency is not significant.
