An investigation was carried out on solar air heaters (SAHs) of different absorber materials. The experiments were conducted to establish the performance of both modified type with composite absorber (black painted GI absorber placed below the toughened glass) and conventional type (black painted GI absorber plate) for flows of air on either sides of schemes. In the modified type, mass flow rate of 0.0169 kg/s, has resulted in increased efficiency for top side, bottom side and both side flows. Compared to top side and bottom side flow, the efficiency was more in both side flows due to increase in the rate of heat transfer. The composite absorber in the modified type, higher solar radiation absorption has provided a large amount of heat transfer to air.
