Outdoor performances of four photovoltaic technologies under four typical meteorological conditions

We present a comparative study of the behavior and performance undervarious weather conditions of four PV modules of different technologies recorded in four typical daysin summer and winter. The study is based on the simultaneous and continuous testing of PV modules under natural conditions of a site located in a coastal area of southern Mediterranean. We essentially interested to the fill factor, the conversion efficiency and the energy performance. A brief description of the experimental set up and the originally method is given after the introductive paragraph. All obtained graphical results allow, at first, the validation of the approach and at second, point out that the daily evolution curves of the fill factor and the efficiency of the PV modules adopt different paces depending on the PV technology. In addition, the results of the energy study showthat the performance ratios of the different technologies aredifferently influenced by weather environment and seasons.
