    Effect on photovoltaic performance of solar panels
    (Altınbaş Üniversitesi / Lisansüstü Eğitim Enstitüsü, 2020) Ali, Mena Muaad Ali; Koç, İbrahim
    Photovoltaic (PV) cells energy production limitation leads to make it important to operate those panels in the best operating conditions. In addition, less sunlight and higher cell temperatures are variables that adversely affect power generation. The potential reduction of cell temperature by one of the alternative thermal control techniques, phase change material (PCM) installation is discussed in this thesis. Three types of PCM (RT15, RT35, and SP25E2) are used together in the proposed system to overcome wide temperature range, in such method to reduce the PV panel temperature. The proposed scheme is simulated using MATLAB. Simulation results show that the effect of high temperature PCM is the overall effect. The use of PCM is disadvantage when the temperature is lower than the PCM melting point. This disadvantage is that the temperature of the panel increases more than the ambient temperature. At the temperatures which were higher than the PCM melting point, the results showed a good effect on decreasing the temperature of the panel and thus increasing the voltage and the maximum power point at peak hours.
