The problem of energy source depletion with the restricted regulation about the emissions make the need for another alternative sours of energy is a worldwide demands. The solar chimney power plant (SCPP) is an optimistic solar energy technology that produces electrical power. In this paper, a 2D analytical study is offered to evaluate the working of the SCPPs’ performance with the varying ground material. Sand, concrete, asphalt, and saturated sand will be used as absorber materials in this study. The Numerical model was done with the realizable k-ɛ turbulence model and the discrete ordinates (DO) solar load model. The model\u27s chimney diameter is 200 mm, collector diameter is 3000 mm, and chimney height is 3500 mm. The model\u27s collector height is 70 mm. It gave the magnitude velocity contour, moving air temperature, pressure, and turbulence characteristics for each unique case. Based on the highest air velocity value inside the SCPP and the resulting power output, the optimal material is chosen
