“…By means of comparison, studies conducted on outdoor exposed a-Si PV modules exhibited approximately 1.76-2.21 %/year performance loss [15]. However, it has been reported that RDa values are of 20.4 % in Malaysia and 18.8 % in Australia and Spain.…”

The productivity of the PV modules installed in southern Algeria is affected by the difficult desert environmental conditions. There are several factors that must be considered in order to ensure the performance and quality of this system. Several works have been conducted in attempts to explain the real performance characterization of the a-Si PV modules when deployed outdoors. The degradation rate can be based on the comparison of the monitoring outdoor performance with the initial indoor measurements taken as references, or by applying LR (Linear Regression) and CSD (Classical Seasonal Decomposition) methods with temperature correction. The a-Si PV modules present light-induced degradation (LID) due to the Staebler-Wronski effect (SWE) and are attributed to recombination-induced breaking of weak Si-Si bonds by optically excited carriers after thermalization, thus producing defects that decrease carrier lifetime. The electrical performance degradation of these modules is very important during the initial exposure to outdoor light due to changes in photoconductivity and dark conductivity. In this study, a pilot platform was created to obtain a database related to the actual environmental conditions and electrical performance parameters of the PV modules. This work assesses the impact of climatic conditions on the behavior of the QS-60DGF modules installed in the URERMS Adrar (research unit in southern Algeria). The degradation evaluation of the QS-60DGF modules was performed with various defects, using electrical properties (I-V/P-V) under daily weather conditions and visual examination (glass breaking). This study is to investigate the degradation rates of a-Si PV module after more than one year of outdoor exposure in desert conditions.

Usually, manufacturers provide PV panels, accompanied with data measured under Standard Test Conditions (STC), i.e. determined at AM1.5 with an irradiance of 1000W/m2 and a cell temperature equal to 25 C. In fact, these conditions do not reflect the reality of natural operation of PV panel conditions and these functional data associated with the real panel operating point may vary from one environment to another due to the change in weather conditions. The characterization of different types of PV panels under natural conditions of operation is, therefore, necessary in order to have a global view about the true electrical performance of different technologies at a given site. This work evaluates the influence of climatic conditions on the behavior of QS-60DGF module which has been installed at the Unit of Research in Renewable energy URERMS Adrar in the southern Algeria. The degradation evaluation of QS-60DGF module with different defects was performed, using (I-V/P-V) characteristics under daily weather conditions and the the visual inspection such as glass breakag. This study is to investigate the degradation rates of a-Si PV module after more than one year of outdoor exposure in desert conditions.
