Performances of PV Systems in Tunisia: Establishment of New Database

Fatma Ahmadi, Tahar Khir, Nabil Khalifa, Ammar Ben Brahim


An experimental study is performed on two different PV systems with amorphous and polycrystalline technologies. Two platforms of the same equipment considered for this study are installed the South West and the North of Tunisia. New experimental data base is established during a period of two years; for which Hourly, daily and monthly solar radiation variations are established. The annual solar radiation obtained in the South West is 18 % higher than that measured in the North.  Experimental results are compared to the available databases CM-SAF and NASA during a whole year (2015). For the PV systems installed in the South West of Tunisia, the annual final yield and performance ratio are determined. A comparison between the data obtained with the amorphous and polycrystalline technologies is conducted.
