EXPERIMENTAL STUDY OF DUST ON PHOTOVOLTAIC SYSTEM EFFICIENCY

Abstract

Electricity is produced around the world mainly using non-renewable energy sources, especially fossil fuels. But these resources can be exhausted at some point in the not-too-distant future. Accordingly, electricity production will be used from various renewable energy sources. Among these sources, solar energy has shown great success for many reasons. For example a permanent source, it is the oldest and most thoroughly researched, and has been tested and implemented for a long time around the world. PV applications have shown that their reliability and efficiency depend on many factors, the most important of which are geography (longitude, latitude and solar density), the environment(temperature, wind, humidity, pollution, dust, rain, etc.) and the type of PV used. One of the most important factors to study Before the construction of any photovoltaic plant is dust , which has a significant impact on the performance of units. Recently ,PV technology has been widely transferred to desert areas as hot spots and has been successful for the system. Besides, these areas are most often dust-prone and dust is the main barrier to PV use. This POSTER reviews research into the impact of dust on the performance of the photovoltaic system as climatic conditions vary. Dust deposition studies have shown that PV units lose 22% to 100% of their efficiency due to the accumulation of dust on their capture surface as well as rain and wind have a significant impact on the performance of the pv unit

L'électricité est produite partout dans le monde principalement à partir des sources non renouvelables en particulier les combustibles fossiles cependant ces ressources disparaitront avec le temps .en conséquence, nous avons recours à la production d'énergie à partir de différents sources qui sont différentes parmi ces sources, l'énergie solaire qui a connu un grand succès pour plusieurs raisons ;source permanent . c'est la plus ancienne et la plus étude ,testée et mise en oeuvre depuis longtemps .les applications photovoltaïques montré que sa fiabilité et son efficacité dépendent de nombreux facteurs dont les plus importants sont la géographie (longitude, l'altitude et densité solaire) ,l'environnement ( température , vent, humidité, pollution, poussière, pluie...etc) et le type de PV utilisé.
