Performance Analysis of a Solar Power Plant Connected to a Small Grid at the IUT of Mulhouse

Abstract

In this paper, the performance of a 1.5 kWp grid- connected photovoltaic (PV) system built at the IUT of Mulhouse, University of Haute Alsace (France) is analyzed. This plant is equipped with polycrystalline silicon photovoltaic panels. In this study, the method based on the IEC 61724 standardized performances from the International Energy Agency is used to calculate the different performance parameters from the collected data. The analysis of the system results covers the whole year 2021 (January 01 to December 31). During this period, the total annual energy supplied by the PV system is 1340,015 kWh. The annual reference yield, the annual PV system yield, the final annual PV system yield are respectively 3.583 h/d, 2.140 h/d and 2.080 h/d. The annual performance ratio is 51.682 %. The annual losses and miscellaneous annual losses of the PV system are 0.060 h/d and 1.630 h/d respectively. These results highlight the relatively good performance of the PV system installed in the city of Mulhouse.
