The present work evaluates the feasibility, from a technical and financial point of view, for the implementation of a photovoltaic (PV) on-grid system that is capable of supplying the electricity demand of two public buildings, one of which is the seat of the municipal town hall and the other, a school, located in Fronteiras, a municipality in the state of Piauí. The study is carried out by analyzing the generator system, presenting the key components for its operation, such as PV modules, inverters, system protection elements, among others, in view of two possible scenarios for the implementation of the PV system, in addition to a real research market, in order to assess the prices charged by companies in the PV generation sector, operating in the state of Piauí. In Case I, the implementation of two independent PV systems is proposed, one for each CU, whereas Case II proposes the installation of a single PV system, capable of supplying the electricity demand of the two CUs, through the energy compensation system. electric. The study was based on ANEEL's Normative Resolution N°. 482/2012, in addition to Technical Standards Nº. 0.20 and Nº. 0.21, of Equatorial Distribuidora do Piauí. Then, using the simulation software PVSyst 7.2, it was possible to obtain data regarding the generation of electric energy for both cases. For Case I, two PV systems were designed, one with 6.6 kWp of installed power, capable of supplying the city hall's demand, and the other with a power of 14.3 kWp, to supply the school's demand. For Case II, a single PV system capable of supplying the demand of the two CUs was designed. Then, the financial analysis was carried out for the two cases, which resulted in an initial investment of BRL 111,103.30, with a return on investment in 3.32 years for Case I and an initial investment of BRL 96,145.00 with a return on investment in 2.86 years. The net present value (NPV) at the end of 25 years was BRL 362,911.58 for Case I and BRL 396,651.84 for Case II. The internal rate of return (IRR) was 33% for Case I and 38% for Case II. Furthermore, the return on investment (ROI) was 1130% for Case I and 1380% for Case II. These analyzes indicate that the proposed systems are viable in both cases.
