In March, Sultan Qaboos University and IEEE Oman organised an exhibition of graduation projects in Muscat, where students from various higher education universities shared their projects.
Students from Sohar University placed second and third in a competition among Oman's higher education institutions for their graduation projects which was supervised by Dr Hussein A Kazem.
About Dr Hussein A Kazem: He has a long scientific and practical experience that extends to 25 years in scientific research and has published 200 papers in scientific journals and conferences and about 50 invited lectures. He has six books to his credit and has won numerous national and international awards.
The preliminary research project was based on the Sohar University project "Comparison & evaluation of solar photovoltaic thermal system (PV/T)" led by electrical engineering and computing students named Yahya Nasser Al-Saeedi, Saleh Ali Al-Farsi, Khamis Said Al-Saidi, Ali Khamis Al-Rushdi, and Saleh Saif Al-Sudairy who won second place in the competition.
Solar energy applications can be divided into: solar thermal systems (T) and solar photovoltaic systems (PV). By merging both into a single system, solar photovoltaic/thermal (PV/T) is formed, a hybrid system that transforms solar energy into electricity and heat while creating a single integrated system. People began researching PV/T in the mid-1970s, focusing on PV/T collectors and the primary goal of increasing PV efficiency. The system also passes water through special tubes through which water passes to carry the heat of the solar modules and cools it when the temperature rises. Then the efficiency of producing electrical energy is highly efficient. This project investigates the effects of solar irradiation and temperature on the current, voltage, power, and energy of direct, spiral, and web flow PV/T systems, with the goal of increasing PV efficiency. The PV/T system is used for drying applications in Oman, such as drying green chili, dates, and fish.
Another research project based on the “Comparison study of dust impact on mono-crystalline and poly-crystalline photovoltaic system" won the third place in the journal led by the Engineering students named Amal Said Al Abdul Salam, Fatima Khalifa Al Abdul Salam, Assila Ali Al Mamari, and Al Anoud Hareb Al Balushi.
Energy is essential to the economic success of any country. Due to the scarcity of fossil fuels and their negative impact on the environment, the need for renewable energy supplies is increasing. Solar energy is one of the fastest-growing renewable energy sources and is quickly becoming a viable alternative for electricity generation in the future. Photovoltaic energy is converted into valuable energy by solar cells. There are environmental factors that affect the performance of these cells, including dust, temperature, wind, humidity, etc. This project aims to test the electrical performance of different photovoltaic modules, taking into account the effect of the daily dust accumulated on them. Also, the effect of two types of artificial dust was tested. The tested PV technologies are monocrystalline and polycrystalline. The experimental results were used to model the dust effect using MATLAB software. It was found that monocrystalline is more affected by dust than polycrystalline PV modules. The results of this study help specify the cleaning method, which is reflected in the feasibility of solar plants.
