The aim for this work is to investigate, both experimentally and theoretically, the effect of abasement inside collector on performance for the Power Plant of Solar Chimney (PPSC). The small prototype of a chimney was built with a chimney height of 6 m, diameter 0.25 m, and collector diameter 7.5 m, covered with glass. The experimental data gathered under actual weather conditions in Baghdad city. Analytical solutions were then used to solve mathematical governing equations of continuity, momentum, and energy using Fortran 90, these results then compared with the experimental results. The experimental results explain that maximum differences between airflow temperature and ambient air reached 25.5 ℃, airflow air velocity 19.2 m/s, the available power 84.6 W at a collector angle of 12°, and a small pebble with tubes in the ground under the collector. In summary, airflow temperature, airflow velocity, and available power increases by tubes fill with water with small pebbles.
