The present paper examines the hypothetical and empirical effects of geometrical parameters via transverse ribs on the back of a jet-impingement solar air heater absorber plate. MATLAB software environment was utilised to develop and solve equations on the steady-state energy balance. Moreover, verification of the performance was done through indoor experiments by employing a solar simulator. The range of parameters included rate of mass flow (ṁ), from 0.007 to 0.039 (kg/s), height of the rib (e) from 0.0017 to 0.0032 (m), relative pitch (P) from 0.01 to 0.04 (m), aspect ratio of the duct was 12, and solar irradiance (I) from 500 to 1000 (W/m²). Finally, the outcomes were compared to smooth ducting hose based on the same condition of flows to examine the improvement of solar air heater thermal efficiency. Therefore, the optimum thermal efficiency was found to be 78% at a (i) mass flowrate of 0.039 (kg/s), (ii) ambient temperature of 297(K), and (iii) a solar irradiance of 1000 (W/m²).
