Solar air heaters are used to capture heat from solar radiation, give it to the working fluid and that hot fluid can be used in various applications. In this research comparison of the thermal Performance of double pass solar air heater with baffled and without baffled absorber plates has been conducted. Highest heat transfer was found to be on black coloured with baffled absorber plate, because the path of air has increased as compare to flat absorber plate. Increased path depends on geometry was equally spaced zig-zag path and air flowing from inlet to outlet in between baffled plate channel. It has been observed that thermal efficiency of the baffled duct solar air heater is about 16-21% higher than the smooth duct solar air heater. Furthermore thermal performance of double pass solar air heater also depends on mass flow rate of air, when mass flow rate decrease efficiency increases.
