The diversification of the Brazilian electric matrix represents a gain in reliability and availability of electricity. In this context, renewable energies have played an increasingly important role in the Brazilian energy sector. Photovoltaic solar energy, in particular, has grown considerably in recent years. One of the factors that contribute to the growth in the use of solar energy is the energy compensation system, which allows grid-connected photovoltaic plants to generate energy credits used for decreasing the bills of plant owners. Along with the increase of installations, there is also a growing demand for preventive and corrective maintenance for these systems. However, few professionals and integrating companies provide consistent maintenance plans for photovoltaic systems, or even know best practices for performing the proper procedures, which represents a problem of reliability, safety and profitability of these systems. In this sense, this work aims to discuss the maintenance of small grid-connected photovoltaic systems, commenting from the project up to the installation of the system, highlighting the relationship of these steps with some aspects of maintenance. Good preventive maintenance practices are described, as well as the relationship between plant maintenance and productivity. Finally, case studies are carried out, in which the importance of implementing appropriate procedures in the installation, operation and maintenance of photovoltaic systems can be assessed.
