Mathematical Relationship Identification for Photovoltaic Systems under Dusty Condition
Solar energy, which comes from the sun in theform of solar irradiance, can be directly converted toelectricity by using photovoltaic (PV) technology. However,the properties related to the nature of semiconductors usedin solar cells, has limited the efficiency of PV systems to 15-20 %. Thus, in order to increase the efficiency of PV systems, some improvements such as applying sun trackers and maximum power point tracking controllers, has been applied in PV system installation. Although these improvements have increased the efficiency of PV systems, afew studies have shown that the deposition of dust accumulation on the PV panels can significantly decrease theefficiency of PV systems. In this study, two Photovoltaic (PV)arrays were examined, of which one was cleaned weekly andthe other was not cleaned at all during the experiment. Thepanels were installed in Serdang, Malaysia, at coordinates2°59'20"N 101°43'30"E and under tropical-based groundconditions. To evaluate the effect of all environmental factors on output power, multiple regression analysis was applied.
