Abstract

This article presents an empirical review of research concerning the impact of dust accumulation on the performance of photovoltaic (PV) panels. After examining the articles published in international scientific journals, many differences between the studies were found within the context of the PV technologies used, the contribution to this type of study from different countries, and the variety in the representation of the results where each study has its unique parameters, testing equipment, and relevant standards. Due to those variations and differences, it has been found that it is very difficult and impractical to compare between results of the corresponding studies. Hence, in addition to the valuable reviews found in literature, this article demonstrates another new perspective that highlights the gaps in the studies related to the impact of dust accumulation on PV panels. The conclusions of this study are considered to be the seed for establishing a new initiative—The Photovoltaic Soiling Index (PVSI)—which would be an indicator for the performance of PV panels under exposure to dust at the Standard Test Conditions (STC), as well as at other operating conditions in different locations around the globe.
