Effets de la poussière et les conditions climatiques sur l'efficacité du système photovoltaïque dans les régions à climat semi-aride Cas de la région de Tlemcen.

Abstract

In order to optimize a photovoltaic system, the climatic and environmental factors of the region must be taken into account. In particular, dust is known to have a significant impact on the optical performance of photovoltaic systems. The aim of this work is to study the dust impact on photovoltaic system efficiency in a semi-arid climate. We conducted a case study in the Tlemcen region (University of Tlemcen). The variation of the relative transmittance with the dust accumulation ratio is analyzed for different periods between April 22 and May 19, 2021. Then we estimated the rate of the lost energy using the HOMER software. The results indicate that the accumulated dust reduces the transmittance by 08% after one month of exposure, as well as the produced photovoltaic energy decreases by 04%. Faced with this loss, it is proposed to use anti-soiling coatings.
