Effects of Temperature and Solar Radiation on Photovoltaic Modules Performances Installed in Oued Keberit Power Plant, Algeria

Abstract

This study presents the measured data of the "Oued Keberit" PV plant over a period of four months (January to April 2022) after nearly 6 years of outdoor exposure to the climate of Souk Ahras, eastern Algeria, in order to evaluate the performance of the solar PV system. This evaluation includes the calculation of PV system performance variables such as module performance, final performance and performance of the module references, system losses, photovoltaic friendly efficiency, system efficiency, performance ratio and capacity factor based on measured data, allowing comparison of actual PV system performance and reference values determined by manifacturers. The results showed that the four-month average values of the parameters Eac, Yr, Yf, PR, η, CF are 1.06375125MWh, 4.08h, 4.25h, 1.06, 16.40%, 60.28% respectively. Also, the high efficiency of the photovoltaic system was obtained during winter, due to the low temperature and the sufficient amount of solar radiation. However, the photovoltaic system generates a lot of energy during summer, although there is less output than during the winter season. This is because summer has maximum values for sunshine duration and solar radiation.
