In the present work, a case study was carried out for the sizing and estimated analysis of the electricity generation of a low voltage Photovoltaic System Connected to the Grid (PSCG) of a residence in the municipality of Tucuruí-PA, until then, single-phase of 127 V, was carried out, however, it will be requested to increase the load to the local concessionaire to 220 V, that is, changing to biphasic in order to meet the electrical specifications of the inverter. It is also considered the estimated cost of investment of R$ 19.661,40 for the installation of this system based on technologies (photovoltaic modules and inverter) and labor available in the market, in addition to the reduction of electric energy for the total return of this investment in the form of savings in the next 6 (six) years, and in the first year (2022) alone, this savings was estimated at R$ 2.520,63 and may increase in the following years with the increase in the electricity tariff , that is, this annual savings reaches 76,92% compared to the previous year (2021) which had an expense of R$ 3.277,09. Regarding the savings, in kWh, in the production of energy from the PSCG, in the first year of generation, it is estimated to generate 3.589,956 kWh, almost the same amount consumed in 2021 (3.747,87 kWh), that is, the photovoltaic arrangement will generate enough energy to save approximately 95,79% of the energy that would be consumed from the distribution network.
