SUMMARY:

Good operation and maintenance (O&M) practices have become increasingly important in the management of photovoltaic systems, however, there is a technical gap and also a gap of knowledgeability in the analysis of this issue. The photovoltaic technology, currently dominated by the use of crystalline silicon cells, stands out for the possibility of distributed generation, in which the consumer can generate energy for his own consumption and also inject it into the electrical grid. Such systems need, however, deeper analysis of feasibility and training of qualified labor, especially for O&M activities. In view of this, this work proposes guidelines for structuring O&M activities of photovoltaic systems connected to the grid, capable of helping to increase the efficiency and useful life of the systems, as well as their economic gains. As theoretical reference, the proposal has a broad review of previous studies to identify the state of the art on the subject. This basis allowed the elaboration of schematic details of O&M activities, allowing a better understanding of procedures and periodicity of actions. To identify multiple factors that interfere in the management of photovoltaic systems connected to the grid, the PV plants of the Federal Institute of Minas Gerais - IFMG were defined as objects of analysis, in which analysis of generation and incidents of failures and O&M activities were performed. In the sequence, procedures were developed for qualitative thermographic inspection of PV modules, for measurement of electrical parameters by the IV curve and for cleaning of photovoltaic systems connected to the grid, as well as, field activities, for validation of procedures. Finally, considering the inexistence of a structured plan to perform O&M in the researched plants, as well as, the incidence of failures, the absence of cleaning of PV modules and the deficiencies in the infrastructure, among others, it is evident the real importance of consolidating an O&M method in grid-connected photovoltaic systems. In this context, this work seeks to contribute through the formulation of O&M guidelines, which may serve as a base for the planning of activities and implementation of preventive and corrective maintenance actions, thus helping to increase energy efficiency and the useful life of the systems, which will make it possible to achieve the expected economic gains.
