    Algeria currently has a number of 24 functional photovoltaic power plants on its national territory, which are poorly investigated. This study focuses on the performance analysis of one of these existing solar power plants. It is located in Ain Skhouna, situated in Saida province, and has a capacity of 30 MWp (polycrystalline solar cell technology). This study was carried out according to the standardized norms IEC 61,724 (IEC) using one year (2018) of data. A linear relationship between the monthly module and ambient temperatures was evaluated (R2 = 0.994). The monthly total loss increases linearly with the increase in monthly ambient temperature and solar irradiation (R2 = 0.98). The system efficiency, PV efficiency, and performance ratio are affected by ambient temperature. The average monthly PV, system, inverter efficiencies, and PR were 13.78%, 13.29%, 96.68%, and 85.52, respectively. These results indicate that this PV power plant remains in very good working condition after two years of service. The effect of climate on PV plant performance was investigated in Algeria by comparing two climates: a semi arid and a hyper-arid. The results indicate that the semi-arid climate is more favorable than the desert climate for PV power plants for producing electricity and that ambient temperature is a more essential parameter than solar irradiation.

    Solar Energy in M’Sila (Algerian Province)
    (Université de M'sila, 2022) Younes Kherbiche; Nabila Ihaddadene; Feres Hadji; Razika Ihaddadene; Merouan Mostefaoui
    An accurate knowledge of solar radiation data for a given location is required for any project aimed at exploiting solar energy. The present paper evaluates the solar energy potential of M'Sila, (internal region of Algeria). This assessment is made based on data collected at the M'Sila weather station for 365 days by 5-minute intervals. The study site is located at a latitude of 35° 42`07``, longitude of 4° 32`43`` and an altitude of 441 m above the sea level. The maximum radiation received in M'Sila during the day does not occur at a fixed time during the year. It fluctuates around an average value of 11:40. This maximum radiation was recorded between 9:14 and 13:59. The representative days of the radiation reaching the ground of M'Sila are different from those relating to extra-terrestrial radiation. They vary from year to year. The month of July is the sunniest month in M’Sila with a total insolation of 790.14 MJ/m2. The month of December is the least sunny month with a total insolation of 242.52 MJ/m2. M'Sila receives a total solar energy of 6316.42 MJ/m2 per year. That means an average insolation of 526.37MJ/m2 per month and 17.31 MJ/m2 per day. M'Sila has an important solar energy potential that deserves to be exploited.
