Abstract

The solar updraft tower system is a renewable-energy technology which convert solar energy to electric power. The system consists of three main parts ; solar collector, updraft tower (chimney) , and wind turbine(s). The current study is aims to estimate the thermal performance of hybrid solar updraft tower by installing PV panel(s) in different positions within .The experimental model was built for this purpose in Al-Kut city-Iraq with geometrical dimensions consist of chimney (6 m in height and 0.3 m in diameter ) made of PVC, collector ( 6 m in diameter and 0.1 m height at the outer edge with 20o inclination). The experimental work was carried out on different days from August to October 2019. The results include that the PV panel(s) can be installed at a different location within the system without significantly effect on the thermal performance . While installing the PV panel on the glass at the collector outlet influences the thermal performance significantly due to the shading area occurred at the important zone within the SCPP system (collector-chimney convergence zone). Consequently, the air velocity difference (enhancement) between this case and the others is (11.46%). On the other hand, the power produced from PV panel(s) installed in a different location is identical for all locations except for the ground location, which is low capacity compared to the other (Power generation enhancement is 136.3% as compared with other location ) due to heating the panel because of the high ground temperature and zero panel inclination. So that, the favorable location for installing the PV panel within the SCPP to reach the optimum overall performance will be the firstly at the chimney, surface of collector inlet, the surface of collector outlet and last location is at the ground. Finally, the hybrid technique (SCPP with PV panel(s) could be the optimum choice to get better overall performance without affecting the thermal performance of the conventional SCPP.
