Abstract

Soiling in photovoltaic system equipment is one of the main parameters that negatively impacts its performance and useful life. This work presents a case study of dirtiness most frequently found in distributed generation photovoltaic systems and the negative effects of no preventive maintenance. The study was based on 96 maintenance reports from a company in the solar energy segment from May 2021 to May 2022. Among the maintenance performed, 84.37% were preventive, 15.63% were corrective, being found 100% were dust on modules and inverters. This study highlighted the problems caused by the soiling in photovoltaic systems and expects to encourage more preventive maintenance due to the real productivity improvement after cleaning.
