Photovoltaic (PV) panels are affected by undesirable elements that exist around them, trees, structures, clouds, etc., as well as natural dirt, and dust accumulation on the PV surfaces. Unfortunately, partial shading falling on top of the PV panels may affect badly the output of photovoltaic arrays. In this study, an exergoeconomic analysis has been performed on the impact of dynamic partial shading created by a mislocated building on a photovoltaic array. Both experimental and theoretical results of this study have been compared on ambient temperature, solar radiation intensity, and shading ratio. The observations have been carried out on clear days starting in June 2018 to Mai 2019. According to the results, the shaded PV exergy efficiency (6.87%) and exergoeconomic parameter (Rex= 0.18508 W/$) are maxima in June and minimum in February (Ex =4.76%, Rex= 0.12228 W/$). As a result of this study, it can be said that the PV array exposed to long-term shading will seriously affect the service life of the PV array.
