A comprehensive review of diagnosis technics for faults occurring in the photovoltaic generator
Keywords:Photovoltaic generator, Degradation, Faults detection, Inspection, Diagnosis, Drones, Cleaning
AbstractRecently, many focuses have been done in the era of renewable energies and especially in solar photovoltaic energy. The photovoltaic generator is considered as the heart of any photovoltaic installations. Any malfunctioning of photovoltaic generators involves degradations overall photovoltaic systems. Therefore, diagnosis technics are required to ensure the detection of failures, correct of damages, the guarantee of a healthy system, and confirm a lengthy lifetime. For these purposes, many recent focuses are elaborated in this field. This paper summarizes a large number of such interesting works, and which englobe a survey of photovoltaic generator degradations forms, types of faults, and diagnosis technics. Comparative study and some critical analyses are given. Benefits and limits of diagnosis technics, in terms of cost estimation, adaptation complexity, efficiency, and robustness are highlighted. Some trending solutions are also discussed.
