Objective of this research is to investigate, both experimentally and theoretically, the effect of added cone inside collector on the Performance of a Solar Chimney Power Plant (SCPP). A small prototype of a solar chimney was built with chimney height of 6m, diameter 0.25m, and collector diameter 7.5m, covered with glass. The experimental data gathered under actual weather conditions in Karbala city. Analytical solutions were then used to solve mathematical governing equations of continuity, momentum and energy using fortran90, these results then compared with the experimental results. The experimental results show that the maximum differences between airflow temperature and ambient air reached 16.5℃, airflow air velocity 16.4 m/s, the available power 84.6 W at a collector angle of 32.7°and a small pebbles on the cone under the collector. In summary, airflow temperature, airflow velocity and available power increases by using a cone under collector with small pebbles
