This study aims to compare two different types of solar air heaters, simple single pass without fins, and simple single pass with fins. In solar air heater with fins three fins are attached to the absorber plate to increase the surface area of the absorber plate and to increase the time period of air flow. A 4 mm single glass plate used to cover the collector, to reduce convective loses to the atmosphere. The solar air heater is insulated to reduce heat losses. These two types of experimental

The collector slope was adjusted to 27° and south faced, which is suitable for the geographical location of Jaipur (26.9260° N, 75.8235° E). Experiment on the solar air heaters was performed and the maximum thermal efficiency was achieved in solar air heater with fins. KEYWORDS: Solar Air Heater, Thermal Efficiency, Solar Flux w/m 2 and absorber plate.
