As part of the scientific activities of College of Engineering at University of Mosul, and in line with its commitment to achieving the Sustainable Development Goals—particularly Goal 4 Quality Education and Goal 9 Industry, Innovation, and Infrastructure—a new research paper in the field of Electrical Engineering has been published by Assistant Professor Dr. Omar Sharaf Al-Din Yahya Al-Yuzbaki, Lecturer Ali Abbawi Mohammed, and Assistant Lecturer Raghad Adeeb Othman, on September 1, 2025, entitled:
“Mitigating mismatch power losses in photovoltaic systems under partial shading: a comparative study of series-parallel and alternative configurations”.

The paper appeared in the International Journal of Applied Power Engineering, which is indexed in Scopus and ranked Q2 as a multidisciplinary journal, as well as Q3 in the field of Electrical and Electronic Engineering.

The study presents a 5 kW photovoltaic (PV) system for residential applications and investigates multiple partial shading scenarios. The results indicate that the highest system efficiency, 82.84%, was achieved when partial shading irradiation (Ir = 500 W/m²) was applied to a single column (5 modules). Conversely, the lowest performance was observed under corner shading and random shading conditions involving 8 modules, where the efficiency dropped to approximately 39.24% and 40.64%, respectively.
