Effect of dust from outdoor environment on the performance of solar photovoltaic panels is natural. There were studies that showed that environmental dust reduces the performance of solar panels, but the results were not clearly quantified. The aim of this study is to determine the extent to which environmental dust affects the performance of solar PV panel in North Western region of Nigeria. The study was carried out in Kazaure Town located 12°39N and 8°24E between November 2015 to February 2016. In this work, electrical performances of photo-voltaic panel were studied experimentally for the effect of environmental dust particles. The experimental data are used for the calculation of the energy efficiency and power output of the PV systems. It was found from the study that the environmental dust reduces the efficiency of solar PV panel by up to 48% and output power by up to 30%.
