The increase in demand for electricity has been growing, it’s necessary to seek alternative solutions to meet this need. One option is to enable generation to be closer to consumption like photovoltaic solar generation. A characteristic of this generation source is its variability and intermittence, which compromises the generation at certain times of the day, interfering with energy availability. A viable solution to minimize these effects is the integration of this source with an energy storage system, ensuring energy supply at times without generation or insufficient generation. The article present the installation steps of a 10.72 kWp project of a grid-connected photovoltaic system with energy storage using lead-acid batteries at UTFPR-Curitiba Campus Neoville. The project has 32 polycrystalline silicon modules 335 W, two 5kW bidirectional inverters and 80 60 Ah lead-acid batteries. Developed in a research and development project in partnership with Copel that provided financial support. The project was based on previous analysis of the installation site, for subsequent delimitation of the area and preparation of the land with placement of canvas and gravel, the shoes were made for the fixing the metallic structure, the placement of the modules and installation of the inverters and the bank of battery in a shelter. The results obtained in photovoltaic generation were 5.29 MWh of generated from May to December 2020 and 2.57 MWh from January to June 2021, in relation to the energy injected from the battery bank the values were 376 kWh and 357,26 kWh, in the same periods, respectively. The energy generated over 14 months showed satisfactory results, both in off-peak hours and in peak hours with the integration of generation and storage.
