Özet:

Most of the energy needed today is obtained from fossil fuels. Both the damages that these fuels cause to the environment and the limited resources have led to the search for alternative energy sources. Solar energy is one of the remarkable renewable energy sources, and is considered as one of the solution to meet the power requirement and to protect the environment. Photovoltaic panel systems are one of the substantial renewable energy sources which are rapidly becoming widespread due to its advantage such as converting directly solar energy into electrical energy. In this study, two different types photovoltaic panels such as monocrystalline and polycrystalline solar panels are examined experimentally and the performance of these panels are assessed. The analysis is carried out for the city of Aydın in Turkey. The experimental measurements are achieved under weather condition of Aydın in August and September months. Besides, the solar radiation is measured using pyranometer device. The panel surface temperature is measured using K type thermocouple. The main purpose of this work is to determine the most suitable panel type for city of Aydın by means of electric power generation and thus to provide scientific data to the investors and companies. The results indicate that for monocrystalline and polycrystalline solar panels, the obtained maximum power are 49.74 W and 46.13 W respectively. In addition, the maximum efficiency of monocrystalline and polycrystalline solar panels is determined to be 13.94% and 12.13%, respectively.
