ABSTRACT
This article presents an experimental study of the effect of dust fouling on the electrical performance of a PV module for different angles of inclination in a semi-arid and temperate environment. In this study, five PV modules were installed above the roof of a laboratory at a height of 3.5 m at inclinations of 0⁰, 15⁰, 30⁰, 45⁰ and 60⁰. The exposure time of the modules without cleaning is 6 months between October and April. In order to analyze the performance of the PV modules, the short-circuit current and the open-circuit voltage were measured every 5 minutes. The results in this study showed that the greatest loss of energy production due to dust was noted at the level of the 15⁰ inclination with a percentage of daily loss of the order of 46% compared to the production of this same module in the case where the latter is considered clean.
Keywords : PV modules, tilt angle, dust deposition, current, voltage
RESUME
Cet article présente une étude expérimentale de l’effet de l’encrassement par la poussière sur la performance électrique des modules PV pour différents angles d’inclinaison dans un environnement semi-aride. Dans cette étude, cinq modules PV sont installés au-dessus du toit à une hauteur de 3,5 m à des inclinaisons de 0⁰, 15⁰, 30⁰, 45⁰ et 60⁰. La durée d’exposition des modules sans nettoyage est de 6 mois entre octobre et avril. Afin d’analyser les performances des modules PV, le courant de court-circuit et la tension en circuit ouvert ont été mesurés toutes les 5 minutes. Les résultats de cette étude ont montré que la plus grande perte de production d’énergie due à la poussière a été constatée au niveau de l’inclinaison de 15⁰ avec un pourcentage de perte journalière de l’ordre de 46% par rapport à la production de ce même module dans le cas où ce dernier est considéré comme propre.
