| Popis: | The paper briefly describes the degradation mechanisms of photovoltaic panels (PVs) in solar plants. After a short presentation of the nature and statistical distribution of defects, structured by type of defect, based on the data processed by TUV Rheinland globally, the paper presents in chapters 3 and 4 data collected and analysed from photovoltaic parks in Romania. This analysis is the starting point for a comprehensive study of the behaviour of photovoltaic parks between 2013-2016, which aims to present equipment nonconformities, design and execution flaws, their causes and effects on energy production and the return rate on investments. At the same time, solutions c*ould be also provided in order to troubleshoot and repower the equipment, as well as effective preventive maintenance solutions, with permanent monitoring of the photovoltaic parks status, including the power degradation rate of PV panels. Documentation elaborated by the ICPE-CA Photovoltaic Systems Laboratory (PV-LAB) team was used to prepare this paper, especially inspections reports and measurements performed in photovoltaic parks in the last two years as a result of a research project carried out in Romania. Also, well-documented papers, developed within the Task 13 - Performance and Reliability of Photovoltaic Systems of the IEA-PVPS Program of Photovoltaic Energy (IEA-PVPS) were used. The purpose of the paper is to raise awareness regarding the problems that can occur during the operation of a PV park before the point where the degradation becomes significant with very high repair costs. |
